-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.

-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.

-Megatron is also used in [NeMo Megatron](https://developer.nvidia.com/nvidia-nemo#nemo-megatron), a framework to help enterprises overcome the challenges of building and training sophisticated natural language processing models with billions and trillions of parameters.
-
-Our codebase is capable of efficiently training very large (hundreds of billions of parameters) language models with both model and data parallelism. To demonstrate how the code scales with multiple GPUs and model sizes, we consider GPT models from 1 billion all the way to 1 trillion parameters. All models use a vocabulary size of 51,200 and a sequence length of 2048. We vary hidden size, number of attention heads, and number of layers to arrive at a specific model size. As the model size increases, we also modestly increase the batch size. We leverage [NVIDIA's Selene supercomputer](https://www.top500.org/system/179842/) to perform scaling studies and use up to 3072 [A100](https://www.nvidia.com/en-us/data-center/a100/) GPUs for the largest model. Each cluster node has 8 NVIDIA 80GB A100 GPUs. The graph below shows that we scale nearly linear up to 1 trillion parameter models running on 3072 GPUs. Note that these results are from benchmark runs and these models were not trained to convergence; however, the FLOPs are measured for end-to-end training, i.e., includes all operations including data loading, optimization, and even logging.
-
-![Scaling Graph](images/Achieved_petaFLOPs.png)
-
-The following table shows both model (MFU) and hardware (HFU) FLOPs utilization for select configurations up to 1T parameters (see [our paper](https://arxiv.org/pdf/2205.05198) for a description of how these are calculated). As the model size increases, we achieve better GPU utilization. For the one trillion parameter model, we reach a MFU and HFU of 56.3% and 57.0%, respectively. Note that these numbers are also measured on benchmark runs and in this case are measured using a data parallel size of one. Data parallelism introduces some overhead due to the gradient all-reduce required between the data parallel groups. However, for large transformer models, this overhead is not large and can almost entirely eliminated by overlapping the gradient all-reduce with backpropagation.
-
-| Model Size | Model FLOPs Utilization | Hardware FLOPs Utilization |
-| :---: | :---: | :---: |
-| 22B   | 41.5% | 43.7% |
-| 175B  | 51.4% | 52.8% |
-| 530B  | 56.0% | 57.0% |
-| 1T    | 56.3% | 57.0% |

-# Setup
-We strongly recommend using the latest release of [NGC's PyTorch container](https://ngc.nvidia.com/catalog/containers/nvidia:pytorch) with DGX nodes. If you can't use this for some reason, use the latest pytorch, cuda, nccl, and NVIDIA [APEX](https://github.com/NVIDIA/apex#quick-start) releases.  Data preprocessing requires [NLTK](https://www.nltk.org/install.html), though this is not required for training, evaluation, or downstream tasks.
-
-You can launch an instance of the PyTorch container and mount Megatron, your dataset, and checkpoints with the following Docker commands:
-```
-docker pull nvcr.io/nvidia/pytorch:xx.xx-py3
-docker run --gpus all -it --rm -v /path/to/megatron:/workspace/megatron -v /path/to/dataset:/workspace/dataset -v /path/to/checkpoints:/workspace/checkpoints nvcr.io/nvidia/pytorch:xx.xx-py3
-```
-
-## Downloading Checkpoints
-We have provided pretrained [BERT-345M](https://ngc.nvidia.com/catalog/models/nvidia:megatron_bert_345m) and [GPT-345M](https://ngc.nvidia.com/catalog/models/nvidia:megatron_lm_345m) checkpoints to evaluate or for finetuning downstream tasks. To access these checkpoints, first [sign up](https://ngc.nvidia.com/signup) for and [setup](https://ngc.nvidia.com/setup/installers/cli) the NVIDIA GPU Cloud (NGC) Registry CLI. Further documentation for downloading models can be found in the [NGC documentation](https://docs.nvidia.com/dgx/ngc-registry-cli-user-guide/index.html#topic_6_4_1).
-
-Alternatively, you can directly download the checkpoints using:
-
-<pre>
-BERT-345M-uncased: wget --content-disposition https://api.ngc.nvidia.com/v2/models/nvidia/megatron_bert_345m/versions/v0.1_uncased/zip -O megatron_bert_345m_v0.1_uncased.zip
-BERT-345M-cased: wget --content-disposition https://api.ngc.nvidia.com/v2/models/nvidia/megatron_bert_345m/versions/v0.1_cased/zip -O megatron_bert_345m_v0.1_cased.zip
-GPT-345M: wget --content-disposition https://api.ngc.nvidia.com/v2/models/nvidia/megatron_lm_345m/versions/v0.0/zip -O megatron_lm_345m_v0.0.zip
-</pre>
-
-The models require vocabulary files to run. The BERT  WordPiece vocab file can be extracted from Google's pretrained BERT models: [uncased](https://s3.amazonaws.com/models.huggingface.co/bert/bert-large-uncased-vocab.txt), [cased](https://s3.amazonaws.com/models.huggingface.co/bert/bert-large-cased-vocab.txt). The GPT [vocab file](https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-vocab.json) and [merge table](https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-merges.txt) can be downloaded directly.
-
-# Usage
-
-After installation, there are several possible workflows. The most comprehensive is:
-1. Data preprocessing
-2. Pretraining
-3. Finetuning (Optional for zero-shot tasks)
-4. Downstream task evaluation or text generation
-
-However, steps 1 and 2 can be replaced by using one of the pretrained models mentioned above.
-
-We've provided several scripts for pretraining both BERT and GPT in the [`examples`](./examples) directory, as well as scripts for both zero-shot and fine-tuned downstream tasks including MNLI, RACE, WikiText103, and LAMBADA evaluation. There is also a script for GPT interactive text generation.
-
-# Training
-## Data Preprocessing
-The training data requires preprocessing. First, place your training data in a loose json format, with one json containing a text sample per line. For example:
-<pre>
-{"src": "www.nvidia.com", "text": "The quick brown fox", "type": "Eng", "id": "0", "title": "First Part"}
-{"src": "The Internet", "text": "jumps over the lazy dog", "type": "Eng", "id": "42", "title": "Second Part"}
-</pre>
-
-The name of the `text` field of the json can be changed by using the `--json-key` flag in [`preprocess_data.py`](./tools/preprocess_data.py) The other metadata are optional and are not used in training.
-
-The loose json is then processed into a binary format for training. To convert the json into mmap format use `preprocess_data.py`. An example script to prepare data for BERT training is:
-<pre>
-python tools/preprocess_data.py \
-       --input my-corpus.json \
-       --output-prefix my-bert \
-       --vocab-file bert-vocab.txt \
-       --tokenizer-type BertWordPieceLowerCase \
-       --split-sentences \
-       --workers 5
-</pre>
-
-The output will be two files named, in this case, `my-bert_text_sentence.bin` and `my-bert_text_sentence.idx`. The `--data-path` specified in later BERT training is the full path and new filename, but without the file extension.
-
-For T5 use the same preprocessing as BERT, perhaps renaming it to:
-<pre>
-       --output-prefix my-t5 \
-</pre>
-
-Some minor modifications are required for GPT data preprocessing, namely, the addition of a merge table, an end-of-document token, removal of sentence splitting, and a change to the tokenizer type:
-<pre>
-python tools/preprocess_data.py \
-       --input my-corpus.json \
-       --output-prefix my-gpt2 \
-       --vocab-file gpt2-vocab.json \
-       --tokenizer-type GPT2BPETokenizer \
-       --merge-file gpt2-merges.txt \
-       --append-eod \
-       --workers 5
-</pre>
-
-Here the output files are named `my-gpt2_text_document.bin` and `my-gpt2_text_document.idx`. As before, in GPT training, use the longer name without the extension as `--data-path`.
-
-Further command line arguments are described in the source file [`preprocess_data.py`](./tools/preprocess_data.py).
-
-## BERT Pretraining
-
-
-The [`examples/pretrain_bert.sh`](./examples/pretrain_bert.sh) script runs single GPU 345M parameter BERT pretraining. Debugging is the primary use for single GPU training, as the code base and command line arguments are optimized for highly distributed training. Most of the arguments are fairly self-explanatory. By default, the learning rate decays linearly over the training iterations starting at `--lr` to a minimum set by `--min-lr` over `--lr-decay-iters` iterations. The fraction of training iterations used for warmup is set by `--lr-warmup-fraction`. While this is single GPU training, the batch size specified by `--micro-batch-size` is a single forward-backward path batch-size and the code will perform gradient accumulation steps until it reaches `global-batch-size` which is the batch size per iteration. The data is partitioned into a 949:50:1 ratio for training/validation/test sets (default is 969:30:1). This partitioning happens on the fly, but is consistent across runs with the same random seed (1234 by default, or specified manually with `--seed`). We use `train-iters` as the training iterations requested. Alternatively, one can provide `--train-samples` which is total number of samples to train on. If this option is present, then instead of providing `--lr-decay-iters`, one will need to provide `--lr-decay-samples`.
-
-The logging, checkpoint-saving, and evaluation interval options are specified. Note that the `--data-path` now includes the additional `_text_sentence` suffix added in preprocessing, but does not include the file extensions.
-
-Further command line arguments are described in the source file [`arguments.py`](./megatron/arguments.py).
-
-To run `examples/pretrain_bert.sh`, make any desired modifications including setting the environment variables for `CHECKPOINT_PATH`, `VOCAB_FILE`, and `DATA_PATH`. Make sure to set these variables to their paths in the container. Then launch the container with Megatron and necessary paths mounted (as explained in [Setup](#setup)) and run the example script.
-
-## GPT Pretraining
-
-The `examples/pretrain_gpt.sh` script runs single GPU 345M parameter GPT pretraining. As mentioned above, single GPU training is primarily intended for debugging purposes, as the code is optimized for distributed training.
-
-It follows largely the same format as the previous BERT script with a few notable differences: the tokenization scheme used is BPE (which requires a merge table and a `json` vocabulary file) instead of WordPiece, the model architecture allows for longer sequences (note that the max position embedding must be greater than or equal to the maximum sequence length), and the `--lr-decay-style` has been set to cosine decay.  Note that the `--data-path` now includes the additional `_text_document` suffix added in preprocessing, but does not include the file extensions.
-
-Further command line arguments are described in the source file [`arguments.py`](./megatron/arguments.py).
-
-`examples/pretrain_gpt.sh` can be launched the same way as described for BERT. Set the env vars and make any other modifications, launch the container with appropriate mounts, and run the script.
-
-## T5 Pretraining
-
-Very similar to BERT and GPT, the `examples/pretrain_t5.sh` script runs single GPU "base" (~220M parameter) T5 pretraining. The primary difference from BERT and GPT is the addition of the following arguments to accommodate the T5 architecture:
-
-* `--kv-channels` sets the inner dimension of the "key" and "value" matrices of all attention mechanisms in the model. For BERT and GPT this defaults to the hidden size divided by the number of attention heads, but can be configured for T5.
-
-* `--ffn-hidden-size` sets the hidden size in the feed-forward networks within a transformer layer. For BERT and GPT this defaults to 4 times the transformer hidden size, but can be configured for T5.
-
-* `--encoder-seq-length` and `--decoder-seq-length` set the sequence length for the encoder and decoder separately.
-
-All of the other arguments remain as they were for BERT and GPT pretraining. Run this example with the same steps described above for the other scripts.
-
-## Distributed Pretraining
-
-The `examples/pretrain_{bert,gpt,t5}_distributed.sh` scripts use the PyTorch distributed launcher for distributed training. As such, multi-node training can be achieved by properly setting environment variables. See the official PyTorch [documentation](https://pytorch.org/docs/stable/elastic/run.html#launcher-api) for further description of these [environment variables](https://pytorch.org/docs/stable/distributed.html#environment-variable-initialization). By default, multi-node training uses the [nccl](https://developer.nvidia.com/nccl) distributed backend. A simple set of additional arguments and the use of the PyTorch distributed module with the `torchrun` elastic launcher (equivalent to `python -m torch.distributed.run`) are the only additional requirements to adopt distributed training. See any of `examples/pretrain_{bert,gpt,t5}_distributed.sh` for more details.
-
-We use two types of parallelism: data and model parallelism. We facilitate two distributed data parallel implementations: a simple one of our own that performs gradient all-reduce at the end of back propagation step, and Torch's distributed data parallel wrapper that overlaps gradient reduction with back propagation computation. To switch between these two options use `--DDP-impl local` or `--DDP-impl torch`, respectively. As expected, Torch distributed data parallelism is more efficient at larger model sizes. For example, for the 8.3 billion parameters model running on 512 GPUs, the scaling increases from 60% to 76% when Torch's distributed data parallel is used. However, the overlapping method requires more memory and for some configurations (e.g., 2.5 billion parameters using 2-way model parallel and 1.2 billion parameters with no model parallel) can make the overall training slower as a result. We empirically found that using a smaller model in those cases improves the training time.
-
-Second, we developed a simple and efficient two-dimensional model-parallel approach. To use the first dimension, tensor model parallelism (splitting execution of a single transformer module over multiple GPUs, see Section 3 of [our paper](https://arxiv.org/pdf/1909.08053.pdf)), add the `--tensor-model-parallel-size` flag to specify the number of GPUs among which to split the model, along with the arguments passed to the distributed launcher as mentioned above. To use the second dimension, sequence parallelism, specify `--sequence-parallel`, which also requires tensor model parallelism to be enabled because it splits across the same GPUs (more details in Section 4.2.2 of [our paper](https://arxiv.org/pdf/2205.05198.pdf)).
-
-To use pipeline model parallelism (sharding the transformer modules into stages with an equal number of transformer modules on each stage, and then pipelining execution by breaking the batch into smaller microbatches, see Section 2.2 of [our paper](https://arxiv.org/pdf/2104.04473.pdf)), use the `--pipeline-model-parallel-size` flag to specify the number of stages to split the model into (e.g., splitting a model with 24 transformer layers across 4 stages would mean each stage gets 6 transformer layers each).
-
-<!-- The number of microbatches in a per-pipeline minibatch is controlled by the `--num-microbatches-in-minibatch` argument. With `WORLD_SIZE` GPUs, `TENSOR_MP_SIZE` tensor-model-parallel size, `PIPELINE_MP_SIZE` pipeline-model-parallel-size, `WORLD_SIZE`/(`TENSOR_MP_SIZE` * `PIPELINE_MP_SIZE`) GPUs will be used for data parallelism. The default values for `--tensor-model-parallel-size` and `--pipeline-model-parallel-size` is 1, which will not implement either form of model parallelism. -->
-
-We have examples of how to use these two different forms of model parallelism the example scripts ending in `distributed_with_mp.sh`:
-
-Other than these minor changes, the distributed training is identical to the training on a single GPU.
-
-The interleaved pipelining schedule (more details in Section 2.2.2 of [our paper](https://arxiv.org/pdf/2104.04473.pdf)) can be enabled using the `--num-layers-per-virtual-pipeline-stage` argument, which controls the number of transformer layers in a virtual stage (by default with the non-interleaved schedule, each GPU will execute a single virtual stage with `NUM_LAYERS / PIPELINE_MP_SIZE` transformer layers). The total number of layers in the transformer model should be divisible by this argument value. Additionally, the number of microbatches in the pipeline (computed as `GLOBAL_BATCH_SIZE / (DATA_PARALLEL_SIZE * MICRO_BATCH_SIZE)`) should be divisible by the `PIPELINE_MP_SIZE` when using this schedule (this condition is checked in an assertion in the code). The interleaved schedule is not supported for pipelines with 2 stages (`PIPELINE_MP_SIZE=2`).
-
-## Activation Checkpointing and Recomputation
-
-To reduce GPU memory usage when training a large model, we support various forms of activation checkpointing and recomputation. Instead of all activations being stored in memory to be used during backprop, as was traditionally the case in deep learning models, only activations at certain "checkpoints" in the model are retained (or stored) in memory, and the other activations are recomputed on-the-fly when needed for backprop. Note that this kind of checkpointing, *activation* checkpointing, is very different from the checkpointing of model parameters and optimizer state, which is mentioned elsewhere.
-
-We support two levels of recompute granularity: `selective` and `full`. Selective recomputation is the default and is recommended in almost all cases. This mode retains in memory the activations that take less memory storage space and are more expensive to recompute and recomputes the activations that take more memory storage space but are relatively inexpensive to recompute. See [our paper](https://arxiv.org/pdf/2205.05198) for details. You should find that this mode maximizes performance while minimizing the memory required to store activations. To enable selective activation recompute simply use `--recompute-activations`.
-
-For cases where memory is very limited, `full` recompute saves just the inputs to a transformer layer, or a group, or block, of transformer layers, and recomputes everything else. To enable full activation recompute use `--recompute-granularity full`. When using `full` activation recompute, there are two methods: `uniform` and `block`, chosen using the `--recompute-method` argument.
-
-* The `uniform` method uniformly divides the transformer layers into groups of layers (each group of size `--recompute-num-layers`) and stores the input activations of each group in memory. The baseline group size is 1 and, in this case, the input activation of each transformer layer is stored. When the GPU memory is insufficient, increasing the number of layers per group reduces the memory usage, enabling a bigger model to be trained. For example, when `--recompute-num-layers` is set to 4, only the input activation of each group of 4 transformer layers is stored.
-
-* The `block` method recomputes the input activations of a specific number (given by `--recompute-num-layers`) of individual transformer layers per pipeline stage and stores the input activations of the remaining layers in the pipeline stage. Reducing `--recompute-num-layers` results in storing the input activations to more transformer layers, which reduces the activation recomputation required in the backprop, thus improving training performance while increasing memory usage. For example, when we specify 5 layers to recompute of 8 layers per pipeline stage, the input activations of only the first 5 transformer layers are recomputed in the backprop step while the input activations for the final 3 layers are stored. `--recompute-num-layers` can be incrementally increased until the amount of memory storage space required is just small enough to fit in the available memory, thereby both maximally utilizing memory and maximizing performance.
-
-
-## Distributed Optimizer
-
-Usage: `--use-distributed-optimizer`. Compatible with all model and data types.
-
-The distributed optimizer is a memory savings technique, whereby the optimizer state is evenly distributed across data parallel ranks (versus the traditional method of replicating the optimizer state across data parallel ranks). As described in [ZeRO: Memory Optimizations Toward Training Trillion Parameter Models](https://arxiv.org/abs/1910.02054), our implementation distributes all optimizer state that does not overlap with the model state. For example, when using fp16 model params, the distributed optimizer maintains its own separate copy of fp32 main params & grads, which are distributed across DP ranks. When using bf16 model params, however, the distributed optimizer's fp32 main grads are the same as the model's fp32 grads, and so the grads in this case are not distributed (although the fp32 main params are still distributed, as they are separate from the bf16 model params).
-
-Theoretical memory savings vary depending on the combination of the model's param dtype and grad dtype. In our implementation, the theoretical number of bytes per parameter is (where 'd' is the data parallel size):
-
-| | Non-distributed optim | Distributed optim |
-|-|-|-|
-| fp16 param, fp16 grads | 20 | 4 + 16/d |
-| bf16 param, fp32 grads | 18 | 6 + 12/d |
-| fp32 param, fp32 grads | 16 | 8 + 8/d |
-
-## FlashAttention
-
-Usage: `--use-flash-attn`. Support attention head dimensions at most 128.
-
-[FlashAttention](https://github.com/HazyResearch/flash-attention) is a fast and
-memory-efficient algorithm to compute exact attention. It speeds up model
-training and reduces memory requirement.
-
-To install FlashAttention:
-```sh
-pip install flash-attn
-```
-
-## GPT-3 Example
-
-In `examples/pretrain_gpt3_175B.sh` we have provided an example of how to configure Megatron to train [GPT-3](https://arxiv.org/abs/2005.14165) with 175 billion parameters on 1024 GPUs. The script is designed for [slurm](https://slurm.schedmd.com/documentation.html) with [pyxis](https://github.com/NVIDIA/pyxis) plugin but can be easily adopted to any other scheduler. It uses 8-way tensor parallelism and 16-way pipeline parallelism. With options `global-batch-size 1536` and `rampup-batch-size 16 16 5859375`, the training will start with global batch size 16 and linearly increase the global batch size to 1536 over 5,859,375 samples with incremental steps 16. The training dataset can be either a single set or a multiple datasets combined with a set of weights.
-
-With full global batch size of 1536 on 1024 A100 GPUs, each iteration takes around 32 seconds resulting in 138 teraFLOPs per GPU which is 44% of the theoretical peak FLOPs.

-## Retro
-
-See:
-
-- `tools/retro/README.md` for an overview.
-- `tools/retro/examples/get_preprocess_cmd.sh` for an example of common preprocessing arguments.
-- `tools/retro/examples/preprocess_data.sh` for an example of how to preprocess data.
-- `tools/retro/examples/pretrain_model.sh` for an example of how to pretrain a model.
-
-Retro is a retrieval-enhanced model that is based on GPT. As described in [Improving language models by retrieving from trillions of tokens](https://arxiv.org/abs/2112.04426), Retro retrieves from a database of document chunks by performing locality search using a sample's tokens. The retrieval database can be large -- often billions or even trillions of tokens -- and provides a more efficient storage mechanism of factual knowledge, when compared to storing factual knowledge implicitly within the network's parameters.
-
-Using Retro requires two steps: 1) preprocessing the retrieval database and pretraining neighbors, and 2) pretraining a model using this data. Please see `tools/retro/README.md` for a detailed overview.
-
-<!--
-## REALM Pipeline
-We are working on implementing the [REALM](https://arxiv.org/pdf/2002.08909.pdf) system. The following sections (will) reflect the three stages of training it. For now it's just the ICT code.
-Loosely, they are pretraining the retriever modules, then jointly training the language model and the retriever, and then finetuning a question answering head on the language model with fixed retriever.
-
-### Inverse Cloze Task (ICT) Pretraining
-1. Have a corpus in loose JSON format with the intention of creating a collection of fixed-size blocks of text as the fundamental units of data. For a corpus like Wikipedia, this will mean multiple sentences per block but also multiple blocks per document.
-Run `tools/preprocess_data.py` to construct one or more indexed datasets with the `--split-sentences` argument to make sentences the basic unit. For the original REALM system, we construct two datasets, one with the title of every document, and another with the body.
-Refer to the following script
-<pre>
-python preprocess_data.py \
-    --input /path/to/corpus.json \
-    --json-keys text title \
-    --split-sentences \
-    --tokenizer-type BertWordPieceLowerCase \
-    --vocab-file /path/to/vocab.txt \
-    --output-prefix corpus_indexed \
-    --workers 5  # works well for 10 CPU cores. Scale up accordingly.
-</pre>
-
-2. Use a custom samples mapping function in place of `megatron/data/realm_dataset_utils.get_block_samples_mapping` if required. To do this, you will need to implement a new function in C++ inside of `megatron/data/helpers.cpp`. The samples mapping data structure is used to select the data that will constitute every training sample in advance of the training loop.
- The samples mapping is responsible for holding all of the required metadata needed to construct the sample from one or more indexed datasets. In REALM, the samples mapping contains the start and end sentence indices, as well as the document index (to find the correct title for a body) and a unique ID for every block.
-3. Pretrain a BERT language model using `pretrain_bert.py`, with the sequence length equal to the block size in token ids. This model should be trained on the same indexed dataset that is used to supply the blocks for the information retrieval task.
-In REALM, this is an uncased bert base model trained with the standard hyperparameters.
-4. Use `pretrain_ict.py` to train an `ICTBertModel` which uses two BERT-based encoders to encode queries and blocks to perform retrieval with.
-The script below trains the ICT model from REALM. It references a pretrained BERT model (step 3) in the `--bert-load` argument. The batch size used in the paper is 4096, so this would need to be run with data parallel world size 32.
-<pre>

-### Building an Index of Block Embeddings
-After having trained an ICT model, you can now embed an entire dataset of blocks by creating a `BlockData` structure. After that has been saved, you can load it
-and wrap it with a `FaissMIPSIndex` to do fast similarity search which is key in the learned information retrieval pipeline. The initial index can be built with the following script, meant to be run in an interactive session. It can leverage multiple GPUs on multiple nodes to index large datasets much more quickly.
-
-<pre>
-python tools/create_doc_index.py \
-    --num-layers 12 \
-    --hidden-size 768 \
-    --ict-head-size 128 \

-# Evaluation and Tasks
-
-We provide several command line arguments, detailed in the scripts listed below, to handle various zero-shot and fine-tuned downstream tasks. However, you can also finetune your model from a pretrained checkpoint on other corpora as desired. To do so, simply add the `--finetune` flag and adjust the input files and training parameters within the original training script. The iteration count will be reset to zero, and the optimizer and internal state will be reinitialized. If the fine-tuning is interrupted for any reason, be sure to remove the `--finetune` flag before continuing, otherwise the training will start again from the beginning.
-
-Because evaluation requires substantially less memory than training, it may be advantageous to merge a model trained in parallel for use on fewer GPUs in downstream tasks. The following script accomplishes this. This example reads in a GPT model with 4-way tensor and 4-way pipeline model parallelism and writes out a model with 2-way tensor and 2-way pipeline model parallelism.
-
-<pre>
-python tools/checkpoint/util.py \
-        --model-type GPT \
-        --load-dir checkpoints/gpt3_tp4_pp4 \
-        --save-dir checkpoints/gpt3_tp2_pp2 \
-        --target-tensor-parallel-size 2 \
-        --target-pipeline-parallel-size 2
-
-</pre>
-
-Several downstream tasks are described for both GPT and BERT models below. They can be run in distributed and model parallel modes with the same changes used in the training scripts.
-
-## GPT Text Generation
-
-We have included a simple REST server to use for text generation in `tools/run_text_generation_server.py`. You run it much like you would start a pretraining job, specifying an appropriate pretrained checkpoint. There are also few optional parameters: `temperature`, `top-k`and `top-p`. See `--help` or the source file for more information. See [examples/run_text_generation_server_345M.sh](examples/run_text_generation_server_345M.sh) for an example of how to run the server.
-
-Once the server is running you can use `tools/text_generation_cli.py` to query it, it takes one argument which is the host the server is running on.
-
-<pre>
-tools/text_generation_cli.py localhost:5000
-</pre>
-
-You can also use CURL or any other tools to query the server directly:
-
-<pre>
-curl 'http://localhost:5000/api' -X 'PUT' -H 'Content-Type: application/json; charset=UTF-8'  -d '{"prompts":["Hello world"], "tokens_to_generate":1}'
-</pre>
-
-See [megatron/text_generation_server.py](megatron/text_generation_server.py) for more API options.
-
-### Detoxify GPT via Self-generation
-We include an example in `examples/detxoify_lm/` to detoxify language models by leveraging the generative power of language models.
-
-See [examples/detxoify_lm/README.md](examples/detxoify_lm/README.md) for step-by-step tutorials on how to perform domain-adaptive training and detoxify LM using self-generated corpus.
-
-
-## GPT Evaluation
-We include example scripts for GPT evaluation on WikiText perplexity evaluation and LAMBADA Cloze accuracy.
-
-### WikiText Perplexity Evaluation
-For even comparison with prior works, we evaluate perplexity on the word-level [WikiText-103 test dataset](https://s3.amazonaws.com/research.metamind.io/wikitext/wikitext-103-v1.zip), and appropriately compute perplexity given the change in tokens when using our subword tokenizer.
-
-We use the following command to run WikiText-103 evaluation on a 345M parameter model.
-<pre>
-TASK="WIKITEXT103"
-
-VALID_DATA=&#60;wikitext path&#62;.txt

-       --no-load-rng
-</pre>
-
-
-### LAMBADA Cloze Accuracy
-To compute LAMBADA cloze accuracy (the accuracy of predicting the last token given the preceding tokens) we utilize a detokenized, processed version of the [LAMBADA dataset](https://github.com/cybertronai/bflm/blob/master/lambada_test.jsonl).
-
-We use the following command to run LAMBADA evaluation on a 345M parameter model. Note that the `--strict-lambada` flag should be used to require whole word matching. Ensure that `lambada` is part of the file path.
-
-<pre>
-TASK="LAMBADA"
-
-VALID_DATA=&#60;lambada path&#62;.json
-VOCAB_FILE=gpt2-vocab.json
-MERGE_FILE=gpt2-merges.txt
-CHECKPOINT_PATH=checkpoints/gpt2_345m

-       --no-load-rng
-</pre>
-
-Further command line arguments are described in the source file [`main.py`](./tasks/main.py)
-
-## BERT Task Evaluation
-### RACE Evaluation
-The following script finetunes the BERT model for evaluation on the [RACE dataset](http://www.cs.cmu.edu/~glai1/data/race/). The `TRAIN_DATA` and `VALID_DATA` directory contain the RACE dataset as separate `.txt` files. Note that for RACE, the batch size is the number of RACE query's to evaluate. Since each RACE query has four samples, the effective batch size passed through the model will be four times the batch size specified on the command line.

-### MNLI Evaluation
-The following script finetunes the BERT model for evaluation with the [MultiNLI sentence pair corpus](https://www.nyu.edu/projects/bowman/multinli/). Because the matching tasks are quite similar, the script can be quickly tweaked to work with the [Quora Question Pairs](https://www.kaggle.com/quora/question-pairs-dataset) (QQP) dataset as well.

-## Llama-2 Inference and Finetuning
-
-The Llama-2 [family of models](https://ai.meta.com/llama/) are an open-source set of pretrained & finetuned (for chat) models that have achieved strong results across a wide set of benchmarks. At the time of release, Llama-2 models achieved among the best results for open-source models, and were competitive with the closed-source GPT-3.5 model (see https://arxiv.org/pdf/2307.09288.pdf).
-
-The Llama-2 checkpoints can be loaded into Megatron for inference and finetuning. See documentation [here](docs/llama2.md).
-
-# Datasets
-We do not host any datasets for GPT or BERT training, however, we detail their collection so that our results may be reproduced.
-
-## Collecting Wikipedia Training Data
-We recommend following the Wikipedia data extraction process specified by Google research: "the recommended pre-processing is to download [the latest dump](https://dumps.wikimedia.org/enwiki/latest/enwiki-latest-pages-articles.xml.bz2), extract the text with [WikiExtractor.py](https://github.com/attardi/wikiextractor), and then apply any necessary cleanup to convert it into plain text."
-
-We recommend using the `--json` argument when using WikiExtractor, which will dump the Wikipedia data into loose json format (one json object per line), making it more manageable on the file system and also readily consumable by our codebase. We recommend further preprocessing this json dataset with nltk punctuation standardization. For BERT training, use the `--split-sentences` flag to `preprocess_data.py` as described [above](#data-preprocessing) to include sentence breaks in the produced index. If you'd like to use Wikipedia data for GPT training you should still clean it with nltk/spacy/ftfy, but do not use the `--split-sentences` flag.
-
-## Collecting GPT Webtext Data
-We utilize the publicly available [OpenWebText](https://github.com/eukaryote31/openwebtext) library from [jcpeterson](https://github.com/jcpeterson/openwebtext) and [eukaryote31's](https://github.com/eukaryote31/openwebtext) work to download urls. We then filter, clean, and deduplicate all downloaded content according to the procedure described in our [openwebtext](./tools/openwebtext) directory. For reddit URLs corresponding to content up to October 2018 we arrived at approximately 37GB of content.
-
-# Reproducibility
-Megatron training is intended to be bitwise reproducible. This means that the same training config run twice in the same HW and SW environment should produce identical model checkpoints, losses and accuracy metric values (iteration time metrics may vary).
-
-There are currently two known Megatron optimizations that break reproducibility whilst still producing almost identical training runs. The following workarounds should be applied in cases where reproducibility is required:
-1. When training using `--bf16`, reproducbility is only obtained when the checkpointing and resume schedule of training is identical. If the checkpointing schedule will change, i.e. checkpointing and resume will occur at different iterations, the option `--no-bias-gelu-fusion` should be used.
-2. Flash attention is nondeterministic. If reproducibility is required do not use `--use-flash-attn`.
-
-These sources of nondeterminism are under active investigation. If you observe nondeterminism in Megatron training under other circumstances please open an issue.

-# Distributed Optimizer
-
-The motivation for the distributed optimizer is to save memory by distributing the optimizer state evenly across data parallel ranks, versus the current method of replicating the optimizer state across data parallel ranks. As described in https://arxiv.org/abs/1910.02054, this branch specifically implements the following:
-
-- [yes] distribute all 'non-overlapping' optimizer state (i.e., model params already in fp32 are NOT distributed)
-- [no] distribute model gradients
-- [no] distribute model parameters
-
-Theoretical memory savings vary depending on the combination of the model's param dtype and grad dtype. In the current implementation, the theoretical number of bytes per parameter is (where 'd' is the data parallel size):
-
-|        | Non-distributed optim | Distributed optim |
-| ------ | ------ | ------ |
-| float16 param, float16 grads | 20 | 4 + 16/d |
-| float16 param, fp32 grads    | 18 | 6 + 12/d |
-| fp32 param, fp32 grads       | 16 | 8 + 8/d  |
-
-The implementation of the distributed optimizer is centered on using the contiguous grad buffer for communicating grads & params between the model state and the optimizer state. The grad buffer at any given moment either holds:
-
-1. all model grads
-2. a 1/d size _copy_ of the main grads (before copying to the optimizer state)
-3. a 1/d size _copy_ of the main params (after copying from the optimizer state)
-4. all model params
-5. zeros (or None), between iterations
-
-The grad buffer is used for performing reduce-scatter and all-gather operations, for passing grads & params between the model state and optimizer state. With this implementation, no dynamic buffers are allocated.
-
-The figures below illustrate the grad buffer's sharding scheme, and the key steps of the distributed optimizer's param update:
-
-## Data flow
-
-![Data flow](images/distrib_optimizer/data_flow.png)
-
-## Sharding scheme
-
-![Sharding scheme](images/distrib_optimizer/sharding_scheme.png)
-
-## Key steps
-
-_(note: using illustrations above, and assuming fp16 grads)_
-
-- Backward pass finishes (grad buffer holds 16 fp16 grad elements)
-- Call reduce-scatter on each DP rank
-- Each DP rank now has 4 elements within the grad buffer that are fully reduced (remaining 12 elements are garbage)
-- Each DP rank copies its relevant 4 fp16 grad elements from the grad buffer into 4 fp32 main grad elements (separate buffer, owned by the optimizer); i.e.
-  - DP rank 0 copies elements [0:4]
-  - DP rank 1 copies elements [4:8]
-  - DP rank 2 copies elements [8:12]
-  - DP rank 3 copies elements [12:16]
-- Optimizer.step()
-- Each DP rank copies its 4 fp32 main (/optimizer) param elements into the corresponding 4 fp16 elements in the grad buffer
-- Call all-gather on each DP rank
-- Grad buffer now contains all 16, fully updated, fp16 model param elements
-- Copy updated model params from grad buffer into their respective param tensors
-- (At this point, grad buffer is ready to be zero'd for the next iteration)

-}
-```
-
-## Usage
-
-### Prepare your environment
-
-The project environment is based on the standard [nvcr docker](nvcr.io/nvidia/pytorch:21.12-py3) of version `nvcr.io/nvidia/pytorch:21.12-py3`.
-
-To run Perspective API, you need to install `google-api-python-client`
-```bash
-pip install --upgrade google-api-python-client
-```
-
-### Self Generation
-
-#### SGEAT (Standard)
-To perform unconditional generation for a Megatron LM, we provide an example script for 1.3B LM.
-
-```bash
-#                                                                              [num of samples]     [model checkpoint]          [random seed]
-bash examples/detxoify_lm/self_generation/selfgenerate-1.3b-unconditional.sh       1000          checkpoints/gpt3/gpt3-1.3b/      2333
-```
-This will generate a jsonl file of  1000 generated text (as a toy example) at `selfgeneration/unconditional_generation_gpt3-1.3b/2333.out`. 
-
-Note that you may want to set your own gpt2 vocab and merge file dir, as well as your output data dir in `selfgenerate-1.3b-unconditional.sh`.
-
-### Annotation
-
-We then use Perspective API to annotate the self generated corpus. Note that you need to fill in your own Perspective API key in the `examples/detoxify_lm/perspective_api_annotate.py`. 
-
-```bash
-python examples/detxoify_lm/perspective_api_annotate.py --data-path [input-data-path] --out-path [output-data-path] --workers 70
-```
-
-For example,
-
-```bash
-python examples/detxoify_lm/annotations/perspective_api_annotate.py --data-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.out --out-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.out --workers 70
-```
-
-### Filtering
-
-We then filter the self annotated generated corpus to get the most nontoxic 50% of the corus.
-
-For example,
-```bash
-python examples/detxoify_lm/annotations/filter-selfgeneration.py --data-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.out --out-path  selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out
-```
-
-This will generate a jsonl file of 500 text of the lowest toxicity (as a toy example) at `selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out`. 
-
-
-### Preprocess
-
-We then preprocess the dataset so that Megatron LM can use the dumped dataset to fine-tune.
-
-```
-bash examples/detxoify_lm/annotations/preprocess.sh selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic.out selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic
-```
-
-This will generate two files as follows
-```bash
-selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document.idx
-selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document.bin
-```
-which will be used in the following domain-adative training step.
-
-### Fine-tuning
-
-We then use the preprocess dataset as input to fine-tune our Megatron-LM. 
-```bash
-#                                                                          [fine-tuning dataset]                                                                      [output-dir]                             [lr]    [bs]      [train-iters]                       [load checkpoint]
-bash examples/detxoify_lm/finetune_gpt_distributed-1.3b.sh    selfgeneration/unconditional_generation_gpt3-1.3b/2333.annotated.nontoxic_text_document         gpt3-1.3b-toy-example-lr-2e-5-bs-512             2e-5     512            78                          checkpoints/gpt3/gpt3-1.3b
-```
-
-This will dump the final checkpoint in `$SHARE_DATA/gpt3-1.3b-toy-example-lr-2e-5-bs-512`. (`$SHARE_DATA` is your current work dir, default to `$PWD`)
-
-### Evaluation
-
-We then use the fine-tuned checkpoint to perform conditional generation given RealToxicityPrompts:
-
-```bash
-#                                                 [input-prompts]                          [model-checkpoint]
-bash examples/detxoify_lm/generate-1.3b.sh     augmented_prompts.jsonl      $SHARE_DATA/gpt3-1.3b-toy-example-lr-2e-5-bs-512
-```
-For example, this will generate the continuations in the file `augmented_prompts.jsonl_output_gpt3-1.3b-toy-example-lr-2e-5-bs-512_seed_31846.jsonl` (seed is a random generated number).
-
-Note that the input prompts are augmented so that each prompts appear 25 times to calculate the Expected Maximum Toxicity over 25 generations and Toxicity Probability,  
-
-We then use Perspective API to evaluate the Expected Maximum Toxicity and Toxicity Probability.   
-
-```bash
-python examples/detxoify_lm/perspective_api.py --data-path "augmented_prompts.jsonl_output_gpt3-1.3b-toy-example-lr-2e-5-bs-512_seed_31846.jsonl" --prompt-path prompts.jsonl --workers 30
-```

-# Reproducing Figures in SC21 Paper
-
-
-This directory contains some of the scripts that were used to produce the
-results in the [Megatron paper](https://arxiv.org/pdf/2104.04473.pdf) that is
-to appear at [SuperComputing 2021](https://sc21.supercomputing.org/). These
-scripts use [Slurm](https://slurm.schedmd.com/documentation.html) with the
-[pyxis plugin](https://github.com/NVIDIA/pyxis), but can be modified for other
-schedulers as well.
-
-
-## Setup
-
-All the cluster-dependent variables are in [`CONFIG.sh`](./CONFIG.sh). Please
-update the unspecified values (in angle brackets `<...>`) before launching any
-scripts.
-
-
-
-## Scripts
-
-Below is a list of scripts that can be used to reproduce various figures in our
-[paper](https://arxiv.org/pdf/2104.04473.pdf):
-
-* [run_table_1.sh](./run_table_1.sh): Table 1 showing weak-scaling throughput
-for GPT models ranging from 1 billion to 1 trillion parameters.
-* [run_figure_11.sh](./run_figure_11.sh): Figure 11 showing the weak-scaling
-performance of pipeline parallelism.
-* [run_figure_12.sh](./run_figure_12.sh): Figure 12 showing the effect of
-the interleaved schedule on a 175B GPT model.
-* [run_figure_13.sh](./run_figure_13.sh): Figure 13 showing the effect of
-different degrees of pipeline and tensor model parallelism on a model with
-162.2 billion parameters.
-* [run_figure_14.sh](./run_figure_14.sh): Figure 14 showing the effect of
-different degrees of data and pipeline model parallelism on a model with
-5.9 billion parameters.
-* [run_figure_15.sh](./run_figure_15.sh): Figure 15 showing the effect of
-different degrees of data and tensor model parallelism on a model with
-5.9 billion parameters.
-* [run_figure_16.sh](./run_figure_16.sh): Figure 16 showing the effect of
-microbatch size.
-* [run_figure_17.sh](./run_figure_17.sh): Figure 17 showing the effect of
-activation recomputation.
-* [run_figure_18.sh](./run_figure_18.sh): Figure 18 showing the effect of
-the scatter-gather communication optimization.

-# How to run lm-eval on Megatron-DeepSpeed checkpoint using the original setup
-
-A great portion of this eval harness feature is inherited from https://github.com/bigscience-workshop/Megatron-DeepSpeed/pull/212, but with code/doc changes (e.g., to support case without pipeline parallelism and MoE models).
-
-This particular setup uses the normal deepspeed checkpoint and requires no conversion to Megatron-LM.
-
-## Prerequisites
-
-1. Install software
-
-On login console with external network
-
-Get lm-eval harness (https://github.com/EleutherAI/lm-evaluation-harness) and `best-download==0.0.7` needed to download some tasks.
-Below package version numbers are what we tested that work.
-```
-(maybe need pip install --upgrade pip)
-pip install best-download==0.0.7 lm-eval==0.2.0 datasets==1.15.1 transformers==4.20.1 huggingface-hub==0.8.1
-```
-
-2. Pre-download needed datasets
-
-some symlinks due to lm-harness' issues with relative position of data
-```
-mkdir data
-cd ../../tasks/eval_harness/
-ln -s ../../examples_deepspeed/MoE/data/ data
-cd ../../examples_deepspeed/MoE/
-```
-<!-- Also make sure `data` is not on one of the limited paritions like WORKSF. -->
-
-Then install datasets for the tasks:
-```
-python ../../tasks/eval_harness/download.py --task_list hellaswag,lambada,triviaqa,webqs,winogrande,piqa,arc_challenge,arc_easy,openbookqa,race,boolq,cb,copa,rte,wic,wsc,multirc,record,anli_r1,anli_r2,anli_r3,wikitext,logiqa,mathqa,mc_taco,mrpc,prost,pubmedqa,qnli,qqp,sciq,sst,wnli
-```
-
-Previously we set `export HF_DATASETS_OFFLINE=1` to make the dataset offline after the above manual download. But somehow now this could trigger error on some kind of online verification for some of the datasets, so it's recommended to only set offline mode when necessary.
-
-<!-- If there are things like custom tokenizers, pre-download those too, e.g.:
-
-```
-python -c "from transformers import AutoTokenizer; AutoTokenizer.from_pretrained('bigscience/oscar_13_languages_alpha_weight')"
-```
-and make sure that `export TRANSFORMERS_OFFLINE=1` is in the script.
-You know there is a custom tokenizer if the training script had something like:
-
-```
---tokenizer-type PretrainedFromHF \
- --tokenizer-name-or-path bigscience/oscar_13_languages_alpha_weight \
-``` -->
-
-3. Prepare the script
-
-<!-- Prepare the run script, replace `variant` with a unique identifier for the current eval so that multiple evals could run in parallel and not all log into the same `results.json` file. so, e.g., `tr9c-1B3-swiglu`
-
-```
-cp examples_deepspeed/run_evalharness_deepspeed.slurm run_evalharness-variant.slurm
-```
-
-now edit `run_evalharness-variant.slurm`
-
-
-Note that the eval code knows to pull the original training args from the checkpoint, so we don't need to pass any of those. And we just need to setup the evaluation args. -->
-
-`ds_evalharness.sh` is the example script.
-
-1. Edit:
-
-```
-PP_SIZE=1
-TP_SIZE=1
-NO_PP="true"
-EP_PARALLEL_SIZE=1
-NUM_NODE=1
-NUM_GPU_PER_NODE=1
-```
-to match the eval topology. 
-
-Edit:
-```
-CHECKPOINT_PATH=
-CONFIG_PATH=
-RESULT_PATH=
-```
-to the checkpoint/ds config you want to use, and where to save the results.
-<!-- If the model fits into 1 gpu, then there is nothing to change.
-
-The eval script will automatically reshape the model if it was of a different topology. -->
-
-
-2. Adjust the following to fit the chosen GPU. As of last check for 1.3B model the settings are one of:
-```
-EVAL_MICRO_BATCH_SIZE=6  # 16GB GPU 1.3B model
-EVAL_MICRO_BATCH_SIZE=12 # 32GB GPU 1.3B model
-```
-
-If you get OOM lower it further.
-
-3. If not using the Deepspeed path, disable it by removing:
-
-```
-    --deepspeed \
-    --deepspeed_config ds_config.json \
-```
-
-If you didn't disable it and the program crashed on checkpoint loading unable to find some key, disable deepspeed as explained above.
-
-Note that for MoE models and for models without pipeline parallelism, currently they might not work for the case without deepspeed.
-
-<!-- ## Eval
-
-Currently it takes 2-3 hours to run on 32GB for 1.3B model, 6-7h for 16GB GPU, so a 20h slurm job should be enough.
-
-When ready, launch:
-```
-sbatch ./run_evalharness-variant.slurm
-```
-
-To monitor progress:
-```
-tail -f tail -f $VARIANT-eval-harness.log
-```
-where the variant is what you set `$VARIANT` to in the slurm script.
-
-The template is set up for 16GB gpu since they are easier to get by. If you change to 32GB, adjust:
-```
-#SBATCH --constraint=v100-32g
-...
-EVAL_MICRO_BATCH_SIZE=12 # 32GB GPU 1.3B model
-```
-
-
-Note that the original ETA at the start of the run can be 10x too longer than the actual outcome. For example it may suggest 18 hours but will complete in 2 hours.
-
-
-## Short eval
-
-if you just want to quickly test that everything can run to the end, edit `tasks/eval_harness/evaluate.py`,  e.g. to run only 10 batches:
-```
-- results = evaluator.evaluate(adaptor, task_dict, False, 0, None)
-+ results = evaluator.evaluate(adaptor, task_dict, False, 0, 10)
-```
-
-(XXX: could be a cmd line option so that code won't need to be modified)
-
-
-## Import into spreadsheet
-
-https://docs.google.com/spreadsheets/d/1CI8Q9RCblLRzUOPJ6ViqBmo284-8ojluQ-CmaEuhuv0/edit?usp=sharing
-
-Note that the spreadsheet format is quite different, so use this script:
-```
-./tasks/eval_harness/report-to-csv.py results.json
-```
-to reformat the json results into csv while changing its shape to match the spreadsheet format
-
-Since some records might be missing or extraneous here is the best way to do it:
-
-1. copy the data from first 2 columns to some place under the main spreadsheet
-
-2. put the pointer to the 3rd column next to where the 2 first columns were copied.
-
-3. import `results.csv` using file-> import -> file ->
-
-Import location: Replace data at selected cell
-
-4. Now it should be easy to align the new records with the old ones - delete irrelevant records and Insert->Cells where data is missing until the first 2 columns match
-
-5. now create 2 cols in the main table on top and now it should be safe to Copy-n-Paste the 2-col data range, without the task/metrics columns into the newly created space. -->

-# Megatron-DeepSpeed Recipes and Scripts
-
-This folder includes various example scripts with DeepSpeed technologies integrated. Below we describe each sub-folder, sorted by last update date.
-
-## Sync with NVIDIA/Megatron-LM (last updated: Jul 2023)
-The ```rebase``` folder includes details about the recent sync with the NVIDIA/Megatron-LM repo (where this repo is forked from). It includes example scripts we used to test after the sync, together with a README documentation about what were tested.
-
-## Data Efficiency (last updated: Feb 2023)
-
-The ```data_efficiency``` folder includes GPT-3 and BERT pretraining examples for DeepSpeed Data Efficiency Library, together with examples of zero-shot evaluation for GPT models and GLUE finetuning for BERT models. Please refer to the detailed tutorials in data_efficiency/README.MD. Currently this folder includes the newest example scripts for GPT/BERT pretraining/eval/finetuning, both with and without DeepSpeed Data Efficiency Library techniques.
-
-## BERT example (last updated: Dec 2022)
-
-The ```bert_with_pile``` folder includes examples about BERT-style model pre-training (using the public Pile data or user's own data) with DeepSpeed integration. Please refer to the readme in the folder for tutorial.
-
-## Azure (last updated: Nov 2022)
-
-We strongly recommend to start with AzureML recipe in the ```azureml``` folder.
-
-If you have a custom infrastructure (e.g. HPC clusters) or Azure VM and VMSS based environments, please refer to the bash scripts in the ```azure``` folder.
-
-## Model Compression (last updated: Aug 2022)
-
-The ```compression``` folder includes examples about layer reduction for task-agnostic compression. Please refer to [this tutorial](https://www.deepspeed.ai/tutorials/model-compression/#11-layer-reduction) about the DeepSpeed Model Compression Library. These recipes are for GPT-style NLG models.
-
-## MoE (last updated: Jun 2022)
-
-Please see the ```MoE``` folder for different training recipes and scripts for Mixture-of-expert based models and dense models. These recipes are for GPT-style NLG models, and currently this is the only folder with MoE training examples.
-
-## Curriculum Learning (last updated: Oct 2021)
-
-Curriculum learning recipes are in the ```curriculum_learning``` folder. Please refer to the detailed tutorials linked inside. These recipes are for GPT-style NLG models.
-Note that the DeepSpeed Data Efficiency Library above includes a more general curriculum learning support. This legacy curriculum learning feature is still compatible, but we recommend using the DeepSpeed Data Efficiency Library above. However, the newer DeepSpeed Data Efficiency Library currently is not compatible with pipeline parallelism. So if you have to use pipeline parallelism, you would need to use this legacy curriculum learning version.

-## Recipes for experimentation on Azure
-
-The recipes have been tested on command line on a cluster setup using Azure VMs and VMSS as well as inside Docker based environments.
-
-To run any of the examples in this folder, please go to the base directory of Megatron-DeepSpeed and run as follows
-
-```bash examples_deepspeed/azure/run-benchmark-model.sh```
-
-### Pre-requisites
-
-To run the above script, you will need to either setup your own dataset and modify the scripts or use our helper scripts to download the publicly available Books dataset and GPT vocab files. Please use the following from the ```dataset``` folder
-
-```bash dataset/download_books.sh```
-
-```bash dataset/download_vocab.sh```
-
-### Run 175B and 1T models
-
-We have included two recipes for the 175B model and the 1T model. To train the model, we assume that the users will modify and tune hyperparameters and configurations by themselves. To facilitate initial training, we have made the recipes runnable with the Books dataset as follows.
-
-```bash examples_deepspeed/azure/run-175b.sh```
-
-```bash examples_deepspeed/azure/run-1t.sh```
-
-### Note about ZeRO stage 3 and CPU offload 
-
-By default, we have enabled ZeRO Stage 3 for both the recipes above. For the 1T model, we have also enabled the CPU-offload feature to save on memory and enable a larger batch size that offers better performance.

-## Megatron-DeepSpeed on AzureML
-Example script for running Megatron-DeepSpeed using Azure Machine Learning.
-
-------
-
-# Workspace Setup
-Setup an AML workspace. Refer to: [set-up doc](https://github.com/Azure/azureml-examples/tree/main/v1/python-sdk#set-up).
-
-# Dataset Preparation
-Create AML Dataset. To run remote AML job, you need to provide AML FileDataset. 
-Refer to [prepare_dataset script](prepare_dataset.py) to upload .bin and .idx files to blob store and on how to create FileDataset.
-
-> Note: The folder `bookcorpus_data` used by [prepare_dataset script](prepare_dataset.py) should not be under `azureml` directories. It is because Azure ML does not allow to include large files (limit: 100 files or 1048576 bytes) for Docker build context.
-
-# Training
-Run Megatron-DeepSpeed on Azure ML. Refer to [aml_submit script](aml_submit.py).

-This ```bert_with_pile``` folder includes examples about BERT pre-training (using [the public Pile data](https://github.com/EleutherAI/the-pile) or user's own data) with DeepSpeed integration. We also provide scripts about preprocessing Pile data and MNLI finetuning.
-
-## Data preprocessing
-```prepare_pile_data.py``` is the script for downloading, decompressing, and preprocessing [the public Pile data](https://github.com/EleutherAI/the-pile). Users can also modify this script to preprocess their own training data.
-
-## BERT pre-training
-```ds_pretrain_bert.sh``` is the script for BERT pre-training integrated with DeepSpeed, supporting [ZeRO](https://www.deepspeed.ai/tutorials/zero/) together with Megatron's tensor-slicing model parallelism. The training hyperparameters follow the [Megatron paper](https://arxiv.org/abs/1909.08053). Note that the pipeline parallelism is currently not supported: DeepSpeed's pipeline parallelism is only integrated with the GPT case, and currently DeepSpeed is not integrated with Megatron's own pipeline parallelism.
-
-As a reference performance number, our measurements show that our example is able to achieve a throughput up to 145 TFLOPs per GPU when pre-training a 1.3B BERT model (with ZeRO stage-1, without model parallelism, with 64 NVIDIA A100 GPUs, with batch size 4096 (64 per GPU), with activation checkpointing).
-
-One thing to note is that this pre-training recipe is NOT a strict reproduction of the [original BERT paper](https://arxiv.org/abs/1810.04805): the Pile data is larger than the data used in original BERT (and the data used by Megatron paper); Megatron-LM introduces some changes to the BERT model (see details in [Megatron paper](https://arxiv.org/abs/1909.08053)); the training hyperparameters are also different. Overall these differences lead to longer training time but also better model quality than original BERT (see MNLI score below), and supporting large model scale by the combination of ZeRO and model parallelism. If you don't have enough computation budget, we recommend to reduce the total training iterations (```train_iters``` in the script) and potentially increase the learning rate at the same time. If you want to strictly reproduce original BERT, we recommend to use our [another BERT example](https://github.com/microsoft/DeepSpeedExamples/tree/master/bing_bert).
-
-## BERT MNLI fine-tuning
-```ds_finetune_bert_mnli.sh``` is the script for BERT MNLI fine-tuning, following the hyperparameters in the [Megatron paper](https://arxiv.org/abs/1909.08053). As a reference, table below present the scores using the model pre-trained based on the script above, comparing with the scores of original BERT and Megatron paper's BERT. Our BERT-Large's score is slightly lower than Megatron paper's, mainly due to the different data we used (Pile data is much diverse and larger than the data in Megatron paper, which potentially has negative effect on small million-scale models).

-| MNLI dev set accuracy | **MNLI-m** | **MNLI-mm** |
-| ---------- |---------- |---------- |
-| BERT-Base, [original BERT](https://arxiv.org/abs/1810.04805) | 84.6 | 83.4 |

-This is an example of how to use DeepSpeed's curriculum learning (CL) feature which provides faster and more stable language model pre-training. Currently it is only integrated for GPT pre-training. Note that there are two curriculum learning examples in two different repos for Megatron-LM GPT-2 pre-training. Both of them have some unique features and limitations. See details in our [tutorial](https://www.deepspeed.ai/tutorials/curriculum-learning/). For technical details please refer to our [paper](https://arxiv.org/abs/2108.06084).

-This directory includes GPT-3/BERT pretraining example scripts for DeepSpeed Data Efficiency Library technologies (curriculum learning, random-LTD, and the two composed together).
-
-You need to install updated DeepSpeed version (>=0.8.0), which contains the DeepSpeed Data Efficiency Library.
-
-Additional tutorial can be found at [DeepSpeed website](https://www.deepspeed.ai/tutorials/data-efficiency/).
-
-Additional technical details can be found in our [random-LTD paper](https://arxiv.org/abs/2211.11586) and [data efficiency paper](https://arxiv.org/abs/2212.03597).
-
-## GPT-3 pretraining and evaluation
-Inside ``gpt`` folder, first the ``ds_analyze_gpt_data_map.sh`` and ``ds_analyze_gpt_data_reduce.sh`` are used for curriculum learning's offline data analysis and indexing.
-
-``gpt/pretrain`` includes the pretraining example scripts. You can choose a setup to run by uncommenting one block in ``ds_pretrain_gpt_1.3B_dense_run.sh``. One thing to note is that in our [random-LTD paper](https://arxiv.org/abs/2211.11586) we did not scale peak learning rate when using less than 100% data, while in our later [data efficiency paper](https://arxiv.org/abs/2212.03597) we find that scaling LR based on used percentage of data helps improve model quality.
-
-``gpt/eval`` includes the zero-/few-shot evaluation example scripts. ``ds_evalharness_parallel_run.sh`` is for zero-shot, and ``ds_evalharness_parallel_run_10shot.sh`` is for 10-shot.
-
-## BERT pretraining and finetuning
-Inside ``bert`` folder, first the ``pile_data_download_preprocess.py`` can be used to download and preprocess the public Pile dataset.
-
-The ``ds_analyze_bert_data_map.sh`` and ``ds_analyze_bert_data_reduce.sh`` are used for curriculum learning's offline data analysis and indexing.
-
-``bert/pretrain`` includes the pretraining example scripts. You can choose a setup to run by uncommenting one block in ``ds_pretrain_bert_336M_run.sh``. One thing to note is that in our [random-LTD paper](https://arxiv.org/abs/2211.11586) we did not scale peak learning rate when using less than 100% data, while in our later [data efficiency paper](https://arxiv.org/abs/2212.03597) we find that scaling LR based on used percentage of data helps improve model quality.
-
-``bert/finetune`` includes the MNLI/QQP/RACE finetuning example scripts following the [Megatron-LM paper](https://arxiv.org/abs/1909.08053). However, we found that the RACE task's accuracy is not very stable and the Megatron-LM paper used a very long number of epochs for MNLI/QQP which is not necessary. Thus we added capability of finetuning other GLUE tasks, and switched to follow the hyperparameters of the [original BERT paper](https://arxiv.org/abs/1810.04805). The corresponding scripts are at ``bert/finetune_glue``, which we recommend to use instead of ``bert/finetune``. Our [data efficiency paper](https://arxiv.org/abs/2212.03597) also uses the scripts under ``bert/finetune_glue`` for GLUE finetuning.

-# Megatron-DeepSpeed Rebase with Optimizations
-
-We rebased and enabled DeepSpeed with the latest Megatron repo. This folder contains examples that demonstrate how to use the new Megatron-DeepSpeed for training GPT like models with new features.
-
-## Rebasing Efforts/Achievements
-New features:
-- Enabled Megatron-LM's sequence parallel.
-- Enabled rotary positional embedding.
-- Enabled FlashAttention v1 and v2.
-- Enabled new fused kernels from NVIDIA.
-
-New optimizations:
-- Enabled attention map memory optimization, where we first generated attention mask on CPU memory and then moved it into GPU memory to avoid out-of-memory errors when training with very large sequence lengths.
-- Position embedding partitioning, where we split weights of position encoding across all GPUs when enabling sequence parallel to further reduce the memory footprint.
-
-Resolved Issues:
-- Fixed the conflicts related to activation checkpointing when DeepSpeed was used with the newest Megatron-LM. NVIDIA introduced new fine-grained partial checkpointing technique, which DeepSpeed was not compatible with. Support for fine-grained checkpointing will be left as future work.
-- Major refactoring to DeepSpeed pipeline parallelism implementation for GPT model in order to work with the newest Megatron-LM.
-- Fixed model checkpoint save/load when DeepSpeed was used with the newest Megatron-LM.
-- Fully verified the performance and correctness of GPT pretraining after rebasing.
-
-## Setting Up the Virtual Environment
-
-```shell
-# clone source code
-git clone https://github.com/microsoft/DeepSpeed.git
-git clone https://github.com/microsoft/Megatron-DeepSpeed.git
-git clone https://github.com/NVIDIA/apex
-
-# creat a new virtual environment
-cd Megatron-DeepSpeed
-python3 -m venv ./venvs/megatron-deepspeed --system-site-packages
-source ./venvs/megatron-deepspeed/bin/activate
-
-# install the newest DeepSpeed
-cd ../DeepSpeed/
-pip install -e .
-
-# install apex
-cd ../apex/
-pip install -v --disable-pip-version-check --no-cache-dir --no-build-isolation --global-option="--cpp_ext" --global-option="--cuda_ext" -e ./
-
-# install pybind11
-cd ../
-pip install pybind11
-```
-
-Megatron-DeepSpeed's sequence parallelism can be combined with the following types of attention.
-
-- Classic attention
-- FlashAttention version 1.x (enabled by `--use-flash-attn-v1`)
-- FlashAttention version 2.x (enabled by `--use-flash-attn-v2`)
-- FlashAttention + Triton (enabled by `--use-flash-attn-triton`)
-
-FlashAttention version 2.x may have numerical stability issues. For the best performance, we recommend using FlashAttention + Triton. 
-We show installation steps of thoes 3 types of FlashAttention
-
-```shell
-
-# install FlashAttention version 1.x
-pip install flash-attn==1.0.4
-
-# install FlashAttention version 2.x
-cd ../
-git clone https://github.com/Dao-AILab/flash-attention.git
-cd flash-attention
-python setup.py install
-
-# install Triton-based FlashAttention
-git clone -b legacy-backend https://github.com/openai/triton
-cd triton/python/
-pip install cmake
-pip install .
-
-cd ../
-git clone -b v1.0.4 https://github.com/HazyResearch/flash-attention
-cd flash-attention
-python setup.py install
-```
-
-## Example Showcase
-
-One of the optimizations enabled from this rebase is to enable Megatron-style long sequence parallelism. To enable sequence parallelism, add the `--sequence-parallel` flag in the training script. We provide two training scripts for ([GPT1.3B](pretrain_gpt_1.3B_seq_parallel.sh) and [GPT30B](pretrain_gpt_13B_seq_parallel.sh)) that enable sequence parallelism, which are available in this foloder.
-
-By default, the degree of sequence parallelism is equal to the degree of model tensor parallelism. The users may also want to ensure that the sequence length is divisible by the degree of sequence parallelism to avoid performance penalties. 
-Please also ensure that your model dimension is compliant with FlashAttention's requirements. For instance, to achieve the optimal performance, the head size should be divisible by 8. Refer to the document of [FlashAttention](https://github.com/Dao-AILab/flash-attention/tree/v1.0.4) for more details.
-
-## Performance Comparison between Old Megatron-DeepSpeed and New Megatron-DeepSpeed
-
-The following experiments are performed on 4 NVIDIA DGX A100-40GB nodes, connected through 8 HDR InfiniBand (200Gb/s per HDR). TP stands for tensor parallelism.
-
-| Sequence Length | Old Megatron-DeepSpeed  (TFLOPS) | New Megatron-DeepSpeed  (TFLOPS) |
-|-----------------|----------------------------------|----------------------------------|
-| 2k              | 25 (TP=32)                       | 68 (TP size=32)                  |
-| 4k              | 28 (TP=32)                       | 80 (TP size=32)                  |
-| 8k              | OoM                              | 86 (TP size=32)                  |
-| 16k             | OoM                              | 92 (TP size=32)                  |
-| 32k             | OoM                              | 100 (TP size=32)                 |
-| 64k             | OoM                              | 106 (TP size=32)                 |
-| 128k            | OoM                              | 119 (TP size=32)                 |
-| 256k            | OoM                              | 94 (TP size=32)                  |
-
-The new Megatron-DeepSpeed is able to support longer sequence lengths without triggering out-of-memory errors because it enables sequence parallelism, which partitions the activation memory when sequence lengths are massive. The new Megatron-DeepSpeed supports FlashAttention, which reduces the memory consumption of the attention map calculation from quadratic to linear complexity with respect to the sequence length. It supports position embedding partitioning, which further reduces the memory consumption. The new Megatron-DeepSpeed can achieve higher TFLPOS because it includes new fused kernels from NVIDIA and supports larger batch sizes using the memory optimizations without triggering out-of-memory errors.

-# ZeRO-Offload++ Tutorials
-
-This folder contains examples that demonstrate how to use the new ZeRO-Offload++ features. 
-
-ZeRO-Offload++ now supports **Twin-Flow** feature.
-
-## Twin-Flow
-
-Instead of all-or-nothing offloading strategy, **Twin-Flow** allows a portion of data to run on CPU and the other part on GPU simultaneously. Thus, we not only mitigate the memory pressure on GPU side by offloading data to CPU, but also utilize both CPU and GPU computation resources more efficiently. 
-
-![Twin-Flow-img](./twin-offload.png)
-
-As shown in above Figure, when ZeRO-Offload is triggered, **Twin-Flow** now allow user to set a new configuration arguement called `ratio` (default value == 1) to adjust the portion of parameter updates on CPU optimizer. For example, if this `ratio==0.4`, it means 0-40% of parameters are updated using CPUAdam on CPU side, while the rest 60% parameters are updatedusing FusedAdam on GPU side.
-
-## How to use
-
-Now **Twin-Flow** can be used at ZeRO stage 3 with Offload. Below we provide two tutorial examples on how to use **Twin-Flow**.
-
-### DeepSpeed Toy Example
-
-Here is a toy example for using **Twin-Flow** inside DeepSpeed repo. 
-
-Under `/tests/small_model_debugging/` folder, Run 
-
-```
-deepspeed partial_offload_test.py --zero 3
-```
-
-### GPT Model Training in Megatron-DeepSpeed
-
-To enable **Twin-Flow** here, we need to add two flags for Megatron configs as follows: 
-
-#### Megatron Configurations
-```
---no-pipeline-parallel \
---cpu-optimizer \
-```
-which have been added to `ds_pretrain_gpt_350M.sh`
-
-#### DeepSpeed Configurations
-On the DeepSpeed side, we need to add follow configurations:
-
-```
-    "offload_optimizer": {
-      "device": "cpu",
-      "pin_memory": true,
-      "ratio": 0.3
-    }
-```
-
-Basically, we need to first enable CPU Offload. Then user can adjust the portion of parameter updating on CPU by adjusting `ratio` here. Its default value is 1, which means all parameter updates happen on CPU side. The above config example with ` "ratio" : 0.3` meaning 0-30% parameters are updating on CPU side, while the other 70% parameter updates happens on GPU side.
-
-#### Tuning suggestion on ratio
-
-To get best performance, we recommend to set this `ratio` value as low as possible without causing GPU memory Out-Ouf-Memory issue.
-
-One additional config on DeepSpeed side is 
-
-```
-  "prescale_gradients": false,
-```
-mainly because right now ZeRO-3 does not support prescale gradients.
-
-All above configs have been added to `ds_config_gpt_TEMPLATE.json`
-
-#### End-to-end Training
-
-To run a sample training of GPT-350M model using Megatron-Deepspeed, simply run as follows:
-
-```
-bash ds_pretrain_gpt_350M.sh
-```
-
-Now the training start running with **Twin-Flow**. Enjoy!
-
-## On-going optimizations
-
-We have some other features inside ZeRO-Offload++ which will come soon, stay tuned!
-
-* Removing uncessary D2H memcpy in ZeRO-offload
-* On-the-fly fp16 to fp32 data casting inside CPUAdam

-# July 2023 sync with NVIDIA/Megatron-LM
-This folder includes details about the recent sync with the NVIDIA/Megatron-LM repo (where this repo is forked from). It includes example scripts we used to test after the sync, together with this README documentation about what were tested.
-
-We also created a [backup branch](https://github.com/microsoft/Megatron-DeepSpeed/tree/before_rebase) which is the version before this sync. This branch is just for comparison tests and for temporary use when debugging the main branch. We do not plan to continue supporting the version before sync.
-
-## List of rebase efforts/achievements
-* Enabling Megatron-LM's sequence parallel.
-* Enabling rotary positional embedding.
-* Enabling FlashAttention v1 and v2.
-* Fix the conflicts related to activation checkpointing when DeepSpeed is used with the newest Megatron-LM since NVIDIA introduced some new fine-grained partial checkpointing techniques which DeepSpeed is currently not compatible.
-* Major refactor to DeepSpeed pipeline parallelism implementation for GPT model in order to work with newest Megatron-LM.
-* Fix model checkpoint save/load when DeepSpeed is used with the newest Megatron-LM.
-* Fully verified the performance and correctness of GPT pretraining after rebasing.
-
-## Test environment
-We used 128 V100 GPUs (8 DGX-2 nodes, 16 GPU per node, inter-node network is InfiniBand with around 660 Gbps measured bandwidth) for the tests. For software, we used DeepSpeed v0.9.5.
-
-## Verified cases and results
-We verified the following cases (matching training/validation curves before/after sync, checkpoint save/load works) for GPT-3 pretraining:
-
-* With DeepSpeed ZeRO stage 1
-* With DeepSpeed ZeRO stage 1 and Megatron-LM's tensor parallelism
-* With DeepSpeed ZeRO stage 1, Megatron-LM's tensor parallelism, and DeepSpeed's pipeline parallelism (i.e., 3D parallelism)
-
-In addition, below is a performance/convergence comparison between before and after this sync.
-
-| Case | TFLOPs (per GPU) | Validation loss at step 200 | Training script |
-| ---- | ---------------- | --------------------------- | --------------- |
-| Before sync, GPT-3 13B, 3D parallelism | 50 | 5.73 | [script (in the backup branch)](https://github.com/microsoft/Megatron-DeepSpeed/blob/before_rebase/examples/before_rebase_test/ds_pretrain_gpt_13B.sh) |
-| After sync, GPT-3 13B, 3D parallelism | 55.6 | 5.71 | [script](ds_pretrain_gpt_13B.sh) |
-
-At last, we provide a [toy example script](ds_pretrain_gpt_125M.sh) that users can try as the first test.
-
-## Flash attention
-We tested and verified that flash attention feature introduced by this sync works properly for GPT pretraining. 
-Our code automatically uses [FlashAttention-2](https://github.com/Dao-AILab/flash-attention) when avaiable.
-
-We compared the training using the [toy example script](ds_pretrain_gpt_125M.sh) and the [toy example script with flash attention](ds_pretrain_gpt_125M_flashattn.sh) on 8 A100 GPUs, and found that FlashAttention (1.0,4) increased training throughput (TFLOPs per GPU) from 25 to 32. When scaling up the model to 2.7B using the same script, FlashAttention-2 improved the training throughput 121 TFLOPs to 132 TFLOPs in comparison to FlashAttention 1.x.
-
-For installation instructions, please refer to [FlashAttention's repository](https://github.com/Dao-AILab/flash-attention).
-
-## Rotary Positional Embedding (RoPE)
-We also tested and verified that the Rotary Positional Embedding (RoPE) introduced by this sync works properly for GPT pretraining. By comparing the training between [without RoPE](ds_pretrain_gpt_1.3B.sh) and [with RoPE](ds_pretrain_gpt_1.3B_rope.sh), we are able to observe that RoPE helps improving the model convergence just like [previous observation](https://blog.eleuther.ai/rotary-embeddings/).
-
-## Notes/TODOs
-* After the sync, DeepSpeed still relies on the older activation checkpointing mechanism (see function ```_checkpointed_forward``` in ```Megatron-DeepSpeed/megatron/model/transformer.py```) since we didn't have time to integrate with the new version yet. Contribution is very welcomed.
-* (Aug 2023 update) With the contribution from 3P users (https://github.com/microsoft/Megatron-DeepSpeed/pull/225), now it's also possible to use Megatron-LM's newer activation checkpointing mechanism. However, currently it's still not compatible with DeepSpeed, so you won't be able to combine it with any DeepSpeed technologies. We DeepSpeed team compared the [older mechanism](ds_pretrain_gpt_1.3B.sh) and [newer mechanism](ds_pretrain_gpt_1.3B_megatron_checkpointing.sh) on 1 DGX-2 node (16 V100), and found that the older mechanism has less memory saving (older max allocated 15241 MB, newer 12924 MB) and higher throughput (older 23.11 TFLOPs newer 17.26 TFLOPs). Thus currently we still recommend using the older mechanism both because of the similar checkpointing performance, and (more importantly) because only older mechnaism is compatible with DeepSpeed (and in this case you can combine with ZeRO to achieve more memeory saving).

-# Sequence Parallelism
-
-This folder contains examples that demonstrate how to use DeepSpeed's sequence parallelism.
-
-## Setting Up the Environment for FlashAttention
-
-DeepSpeed's sequence parallelism can be combined with the following types of attention.
-
-- Classic attention
-- FlashAttention (enabled by `--use-flash-attn`)
-- FlashAttention + Triton (enabled by `--use-flash-attn-triton`)
-
-For the best performance, we recommend using FlashAttention + Triton. Here are the installation steps and the versions we have tested. Note that FlashAttention is compatible only with Turing, Ampere, Ada, or Hopper GPUs.
-
-```shell
-# install triton
-git clone -b legacy-backend https://github.com/openai/triton
-cd triton/python/
-pip install cmake
-pip install .
-
-# install
-cd ${WORK_DIR}
-git clone -b v1.0.4 https://github.com/HazyResearch/flash-attention
-cd flash-attention
-python setup.py install
-```
-
-## Enabling Sequence Parallelism
-
-To enable sequence parallelism, set the degree of parallelism using the `--ds-sequence-parallel-size` argument. Ensure that the number of attention heads is divisible by this value.
-Ensure your model configuration is compliant with FlashAttention's requirements. For instance, to achieve optimal performance, the head size should be divisible by 8. Refer to the document of [FlashAttention](https://github.com/Dao-AILab/flash-attention/tree/v1.0.4) for more details.
-
-Some working examples ([GPT1.3B](ds_pretrain_gpt_1.3B_seq_parallel_32k.sh), [GPT30B](ds_pretrain_gpt_30B_seq_parallel_32k.sh)), that enable sequence parallelism, are available in this foloder.
-
-Please note that our sequence parallelism feature is currently incompatible with Megatron-LM's tensor or pipeline parallelism.

-# Universal Checkpoint examples
-
-This folder contains example scripts that demonstrate how to use Universal Checkpoints to change the number of GPUs when training with ZeRO. With Universal Checkpoints, training can be resumed with a different parallelism degree on any of tensor slicing (TP), pipeline parallelism (PP), sequence parallelism (SP) and data parallelism (DP). Using universal checkpoints involves the following three steps:
-
-1. ZeRO-based training run, optionally combining TP and PP or SP, that creates normal ZeRO checkpoints.  
-2. Converting ZeRO checkpoint into the universal format using `ds_to_universal.py` utility of DeepSpeed.
-3. Resuming training with the universal checkpoint, on a different number of GPUs.
-
-## ZeRO stage 1 training
-For ZeRO stage 1, we provide bash scripts for bf16 and fp16 training examples corresponding to the steps 1 and 3 above. The step 1 scripts launch a training run of TP=PP=DP=2 of 200 iterations that creates a checkpoint every 100 iterations. The step 3 scripts load a universal checkpoint of iteration 100 and resume training with TP=PP=2 and DP=1 for an additional 100 iterations. Users can modify these scripts to try out other save and resume 3D combinations (e.g., save TP=PP=DP=1 and resume TP=PP=DP=2). Tensorboard logs are created by both step 1 and 3 scripts to enable visual inspection of how well the loss curves of the initial and resumed training runs match, especially at iteration 101.  
-
-1.  bf16:
-    * run_bf16.sh: step 1
-    * run_universal_bf16.sh: step 3
-
-2. fp16:
-    * run_fp16.sh: step 1 
-    * run_universal_fp16.sh: step 3
-
-Please note that these scripts should be run from the root folder of the repo (i.e., two levels above this README). For illustration, here are the commands for running the bf16 example. 
-
-### Download and Pre-process Training Dataset
-Before executing the steps below, you can download and pre-process the training set using the following commands (see [here](https://github.com/bigscience-workshop/Megatron-DeepSpeed?tab=readme-ov-file#quick-pre-processing-to-start-training-with) for more details):
-```bash
-wget https://huggingface.co/bigscience/misc-test-data/resolve/main/stas/oscar-1GB.jsonl.xz
-wget https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-vocab.json
-wget https://s3.amazonaws.com/models.huggingface.co/bert/gpt2-merges.txt
-xz -d oscar-1GB.jsonl.xz
-python tools/preprocess_data.py \
-    --input oscar-1GB.jsonl \
-    --output-prefix my-gpt2 \
-    --vocab-file gpt2-vocab.json \
-    --dataset-impl mmap \
-    --tokenizer-type GPT2BPETokenizer \
-    --merge-file gpt2-merges.txt \
-    --append-eod \
-    --workers 8
-```
-
-NOTE: Make sure to update your `BASE_DATA_PATH` path in the `run_[bf16/fp16].sh` and `run_universal_[bf16/fp16].sh` scripts to point to the pre-processed data.
-
-### Step 1: Create ZeRO checkpoint
-```bash 
-  bash examples_deepspeed/universal_checkpointing/run_bf16.sh 
-```
-By default the script will create the checkpoints in folder `z1_uni_ckpt/checkpoints/gpt2/z1/bf16/tp2_pp2_dp2_toy`
-
-### Step 2: Convert ZeRO checkpoint of iteration 100 to Universal format
-Assuming the DeepSpeed source code is cloned into the home folder, the following command will generate universal checkpoint for iteration 100. 
-
-```bash
-python ${HOME}/DeepSpeed/deepspeed/checkpoint/ds_to_universal.py \
-    --input_folder z1_uni_ckpt/checkpoints/gpt2/z1/bf16/tp2_pp2_dp2_toy/global_step100 \
-    --output_folder z1_uni_ckpt/checkpoints/gpt2/z1/bf16/tp2_pp2_dp2_toy/global_step100_universal
-```
-Note that we chose to create the universal checkpoint in the same checkpoint folder as the ZeRO checkpoint. This maintains the normal checkpoint folder structure expected by the Megatron-DeepSpeed code, which makes it easy to load universal checkpoints with little/no script or code changes. For clarity, we show below the contents of the checkpoint folder after creation of the universal checkpoint. Note that the conversion script creates `global_step100_universal` folder and `latest_universal` file.   
-
-```bash
-ls -l z1_uni_ckpt/checkpoints/gpt2/z1/bf16/tp2_pp2_dp2_toy/
-total 48
-drwxr-xr-x 2 user group  4096 Oct 21 08:51 global_step100
-drwxr-xr-x 3 user group  4096 Oct 21 09:28 global_step100_universal
-drwxr-xr-x 2 user group  4096 Oct 21 09:01 global_step200
--rw-r--r-- 1 user group    14 Oct 21 09:50 latest

--rw-r--r-- 1 user group    24 Oct 21 09:28 latest_universal
--rwxr--r-- 1 user group 24177 Oct 21 09:50 zero_to_fp32.py
-```
-
-### Step 3: Resume training with Universal checkpoint of iteration 100
-```bash 
-bash examples_deepspeed/universal_checkpointing/run_universal_bf16.sh
-```
-This resumption script effects the loading of universal checkpoint rather than the ZeRO checkpoint in the folder by passing `--universal-checkpoint` command line flag to the main training script (i.e., `pretrain_gpt.py`). 
-
-Please see the corresponding [pull request](https://github.com/microsoft/Megatron-DeepSpeed/pull/276) for visualizations of matching loss values between original and universal checkpoint runs for bf16 and fp16 examples.
-
-Combining sequence parallelism with data parallelism is another good use case for universal checkpointing, see [sp pull request](https://github.com/microsoft/DeepSpeed/pull/4752) for example and visualization of matching loss values.
-
-### TensorBoard Log Analysis
-
-The Universal Checkpointing example includes a TensorBoard analysis script that will generate `csv` files and `png` plots across the unviersal checkpointing training steps for comparison of training and validation loss curves.
-
-After Step 3 is completed, the script may be executed as follows:
-```bash
-bash examples_deepspeed/universal_checkpointing/run_tb_analysis.sh z1_uni_ckpt
-```
-
-The script will output the following `csv` files:
-  - uc_out_tp_2_pp_2_dp_2_sp_1.csv
-  - uc_out_tp_2_pp_2_dp_1_sp_1.csv
-  - val_uc_out_tp_2_pp_2_dp_2_sp_1.csv
-  - val_uc_out_tp_2_pp_2_dp_1_sp_1.csv
-
-The script will also output the following `png` files:
-  - uc_char_training_loss.png
-  - uc_char_validation_loss.png
-
-Below is the visualization of the `png` files generated from this example.

-# Data Pipeline
-
-## Data pre-processing
-
-Data preprocessing is built around the following classes:
-
-1. `MMapIndexedDatasetBuilder`
-2. `MMapIndexedDataset`
-
-At the moment, an end-to-end data preprocessing implementation is left to the user. See the class docstring(s) for more details.
-
-#### MMapIndexedDatasetBuilder
-
-The `MMapIndexedDatasetBuilder` is capable of building and merging `MMapIndexedDataset` instances.
-
-#### MMapIndexedDataset
-
-The `MMapIndexedDataset` class is the lowest-level data interface in Megatron Core. Internally, an `MMapIndexedDataset` instance references two binaries: the data file (`.bin`) contains document/sequence data and the index file (`.idx`) contains document/sequence metadata.
-
-The index file stores dataset-level metadata first:
-- The index header, for backward compatibility
-- The index version, for backward compatibility
-- A numeric code corresponding to the data type used to write data to the data file
-- The number of sequences in the dataset
-- The number of documents in the dataset
-
-The index file stores document-level and sequence-level metadata second:
-- In order, the number of elements per sequence
-- In order, the byte offset (pointer) per sequence
-- In order, the consecutive sequence index range `[...)` per document
-- In order, the mode per sequence (in the multimodal case)
-
-## Data loading: construction
-
-Building the data loaders is a distributed-aware process built around the following classes:
-
-1. `BlendedMegatronDatasetConfig`
-2. `BlendedMegatronDatasetBuilder`
-3. `MMapIndexedDataset`
-3. `MegatronDataset`
-4. `BlendedDataset`
-
-See the class docstrings for more details.
-
-#### BlendedMegatronDatasetConfig (extendable)
-
-The `BlendedMegatronDatasetConfig` class parameterizes the `BlendedMegatronDatasetBuilder` and in turn the `MegatronDataset` and `BlendedDataset`.
-
-Different training/inference regimes will require different extensions e.g. the `GPTDatasetConfig`
-
-#### BlendedMegatronDatasetBuilder
-
-The `BlendedMegatronDatasetBuilder` class builds the highest-level data interfaces in Megatron Core.
-
-**NB:** All ranks should attempt to build the dataset via the `BlendedMegatronDatasetBuilder` or the program will hang. Which ranks follow through on their attempts can be controlled via the `BlendedMegatronDatasetConfig`.
-
-#### MMapIndexedDataset
-
-The `MMapIndexedDataset` class is the lowest-level data interface in Megatron Core.
-
-The `MMapIndexedDataset` should already exist on disk before attempting to build any of the high-level data interfaces.
-
-
-#### MegatronDataset (extendable)
-
-The `MegatronDataset` abstract class is a high-level data interface in Megatron Core. It is an abstraction built upon the `MMapIndexedDataset`.
-
-Different training/inference regimes will require different extensions e.g. the `GPTDataset`
-
-#### BlendedDataset
-
-The `BlendedDataset` class is a high-level data interface in Megatron Core. It is an abstraction built upon the `MegatronDataset`.
-
-The `BlendedDataset` is only necessary when a blend multiple data distributions, i.e. multiple `MegatronDataset` instances, should contribute to a certain dataset split. The blend can be controlled via the `BlendedMegatronDatasetConfig`.
-
-## Data loading: implementation
-
-### GPTDataset
-
-The `GPTDataset` is parameterized by the following variables: the underlying `MMapIndexedDataset` instance `indexed_dataset`, the split indices `indexed_indices` (the congituous subset of document or sequence indices used for training, validation, and testing), the number of samples `N`, the sequence length `S`, and the random seed `R`.
-
-The `GPTDataset` creates three index mappings to facilitate lookup: (1) the document index, (2) the sample index, and (3) the shuffle index.
-
-1. The document index _Do_idx_ is a 1-D array mapping from _i_ to document index of length `E * |indexed_indices|` where `E` corresponds to the minimum number of epochs such that `E * |indexed_indices| >= N`. The document index is shuffled according to `R`.
-
-    ```
-    Given:
-
-    N = 15
-    indexed_indices = [5, 6, 7, 8, 9]
-    E = 3
-
-    Then, for example:
-
-    Do_idx = [8, 8, 9, 6, 7, 5, 8, 5, 6, 6, 5, 9, 7, 7, 9]
-    ```
-
-2. The sample index _Sa_idx_ is a 2-D array mapping from _j_ to pairs of (_i_, _Do_idx_[ _i_ ] offset) of shape `[N + 1, 2]`. The rows _j_ and _j_ + 1 serve as the left and right bounds for the _j_-th sample. 
-
-    ```
-    Given:
-
-    S = 1024
-
-    Then, for example:
-
-    Sa_idx[0] = (0, 0)
-    Sa_idx[1] = (0, 1024)       => Do_idx[0] has length greater than S
-    Sa_idx[2] = (1, 512)        => Do_idx[0] has length 1536
-    Sa_idx[3] = (2, 0)          => Do_idx[1] has length 1536
-    Sa_idx[4] = (5, 300)        => Do_idx[2:5] are shorter documents relative to Do_idx[0:2]
-    Sa_idx[5] = (6, 24)         => Do_idx[5] has length 1300
-    ```
-
-3. The shuffle index _Sh_idx_ is a 1-D array mapping from _k_ to _j_ of length `N`. The shuffle index is shuffled according to `R`.
-
-    ```
-    Given
-
-    N = 10
-
-    Then, for example:
-
-    Sh_idx = [4, 0, 2, 6, 1, 9, 5, 8, 7, 3]
-    ```
-
-To query the `GPTDataset` for the _k_-th sample we do the following
-
--  Use the shuffle index to get the index _j_ into the sample index.
-
-    ```
-    j = Sh_idx[k]
-    ```
-- Use the sample index to get the left and right sample-bounding indices into the document index and the starting token offset for each document.
-
-    ```
-    i, offset = Sa_idx[j]
-    i_next, offset_next = Sa_idx[j + 1]
-    ```
-- Use the document index to retrieve `S` tokens from consecutive (in the document index) documents.
-
-    ```
-    sample = []
-    sample += indexed_dataset[Do_idx[i]][offset:]
-    if i != i_next:
-        sample += indexed_dataset[Do_idx[i + 1:i_next]]
-    sample += indexed_dataset[Do_idx[i_next]][:offset_next]
-    ```
-
-To save time during initialization, each index is built/cached sequentially on one process rank and subsequently loaded in parallel on other process ranks. The cached indices are unique to a hash generated in the `MegatronDataset.__init__` function.
-
-### BlendedDataset
-
-The `BlendedDataset` is parameterized by the following variables: the underlying `MegatronDataset` instances `D`, the weights `W` (one per dataset), and the size `S`. The `BlendedDataset` will draw samples from contributing datasets in proportion to the weights until achieving a composite dataset of the desired size. During each sampling step, we draw a single sample from the dataset which has the greatest sampling error.
-
-The `BlendedDataset` creates two "blending" indices to facilitate lookup: (1) the dataset index and (2) the dataset sample index.
-
-1. The dataset index _Da_idx_ is a 1-D array mapping from _i_ to dataset index of length `S`.
-
-    ```
-    Given
-
-    D = [d0, d1, d2]
-    W = [1/2, 1/4, 1/4]
-    S = 4
-
-    Then, for example:
-
-    Da_idx = [0, 1, 2, 0]
-
-    ```
-
-2. The dataset sample index _Sa_idx_ is a 1-D mapping from _i_ to the sample index for dataset _Da_idx[i]_ of length `S`.
-
-    ```
-    Given
-
-    Da_idx = [0, 1, 2, 0]
-
-    Then, for example:
-
-    Sa_idx = [0, 0, 0, 1]
-    ```
-
-To query the `BlendedDataset` for the _k_-th sample we do the following
-
-- Use the dataset index to retrieve the corresponding dataset from `D` and the dataset sample index to retrieve the corresponding sample from that dataset.
-
-    ```
-    sample = D[Da_idx[k]][Sa_idx[k]]
-    ```
-
-To save time during initialization, each index is built/cached sequentially on one process rank and subsequently loaded in parallel on other process ranks. The cached indices are unique to a hash generated in the `BlendedDataset.__init__` function.

-    0. (optional) create Gloo distributed groups

-
-    Model Parallelism
-    -----------------
-
-    tensor_model_parallel_size (int): Intra-layer model parallelism. Splits tensors across GPU ranks. Defaults to 1.
-
-    context_parallel_size (int): Splits network input along sequence dimension across GPU ranks. Defaults to 1.
-
-    pipeline_model_parallel_size (int): Inter-layer model parallelism. Splits transformer layers across GPU
-        ranks. Defaults to 1.
-
-    virtual_pipeline_model_parallel_size (int): Interleaved pipeline parallelism is used to improve performance by
-        reducing the pipeline bubble.  Considers a transformer block as a list of smaller transformer (virtual) blocks.
-        The number of virtual blocks per pipeline model parallel rank is the virtual model parallel size.  See Efficient
-        Large-Scale Language Model Training on GPU Clusters Using Megatron-LM: https://arxiv.org/pdf/2104.04473.pdf for
-        more details.  Defaults to None.
-
-    sequence_parallel (bool): Makes tensor parallelism more memory efficient for LLMs (20B+) by
-        parallelizing layer norms and dropout sequentially.  See Reducing Activation Recomputation in Large Transformer
-        Models: https://arxiv.org/abs/2205.05198 for more details. Defaults to False.
-
-    expert_model_parallel_size (int): Distributes Moe Experts across sub data parallel dimension. Defaults to False.
-
-    Initialization
-    --------------
-
-    perform_initialization (bool, default=True): If true, weights are initialized. This option can be useful when you
-        know you are going to load values from a checkpoint.
-
-    use_cpu_initialization: (bool, default=False): When set to False, we initialize the weights directly on the GPU.
-        Transferring weights from CPU to GPU can take a significant amount of time for large models. Defaults to False.
-
-    Training
-    --------
-
-    fp16 (bool): If true, train with fp16 mixed precision training. Defaults to False.
-
-    bf16 (bool): If true, train with bf16 mixed precision training. Defaults to False.
-
-    params_dtype (torch.dtype): dtype used when intializing the weights. Defaults to torch.float32
-
-    timers (optional, default=None): TODO
-
-    Optimizations
-    -------------
-
-    gradient_accumulation_fusion (bool): If true, fuses weight gradient accumulation to GEMMs. Requires the custom CUDA
-        extension fused_weight_gradient_mlp_cuda module. To use gradient_accumulation_fusion you must install APEX with
-        --cpp_ext and --cuda_ext. For example: "pip install --global-option=\"--cpp_ext\" --global-option=\"--cuda_ext\"
-        ". Note that the extension requires CUDA>=11. Otherwise, you must turn off gradient accumulation fusion.
-        Defaults to False.
-
-    async_tensor_model_parallel_allreduce (bool, default=True): If true, enables asynchronous execution of
-        tensor-model-parallel all-reduce with weight gradient compuation of a column-linear layer.  Defaults to False.
-
-    tp_comm_overlap (bool, default=False): If true, allows overlapping of Linear layer execution with tensor parallel
-        communication collectives like AllGather/ReduceScatter. Overlapping is done for the linear layers wherever possible
-        during the forward and the backward pass.  Defaults to False.
-
-    tp_comm_split_ag (bool, default=True): If true, allows All-Gather overlap with Fprop GEMM. Don't care if tp_comm_overlap 
-        is False.
-
-    tp_comm_split_rs (bool, default=True): If true, allows Reduce-Scatter overlap with Fprop GEMM. Don't care if 
-        tp_comm_overlap is False.
-
-    tp_comm_bulk_dgrad (bool, default=True): If true, allows All-Gather overlap with Bprop activation gradient GEMM. Don't 
-        care if tp_comm_overlap is False.
-
-    tp_comm_bulk_wgrad (bool, default=True): If true, allows Reduce-Scatter overlap with Bprop weight gradient GEMM. Don't 
-        care if tp_comm_overlap is False.
-
-    Parallelism
-    -----------
-
-    finalize_model_grads_func (optional): Function that finalizes gradients on all workers. Could include ensuring that
-        grads are all-reduced across data parallelism, pipeline parallelism, and sequence parallelism dimensions.
-
-    Pipeline Parallelism
-    --------------------
-
-    pipeline_dtype (required): dtype used in p2p communication, usually params_dtype
-
-    grad_scale_func (optional, default=None): If using loss scaling, this function should take the loss and return the
-        scaled loss. If None, no function is called on the loss.
-
-    enable_autocast (bool): If true runs the forward step function inside torch.autocast context. Default is False.
-
-    autocast_dtype (torch.dtype): dtype to pass to torch.amp.autocast when enabled. Default is pipeline_dtype.
-    
-    variable_seq_lengths (bool, default=False): Support for variable sequence lengths across microbatches. Setting this
-        communicates the size of tensors during pipeline parallelism communication, because of this extra overhead it
-        should only be set if the sequence length varies by microbatch within a global batch.
-
-    num_microbatches_with_partial_activation_checkpoints (int, default=None): If int, set the number of microbatches
-        where not all of the layers will be checkpointed and recomputed. The rest of the microbatches within the window
-        of maximum outstanding microbatches will recompute all layers (either full recompute or selective recompute). If
-        None, the checkpoint and recompute will be left up to the forward_step function.
-
-    overlap_p2p_comm (bool, optional, default=False): When True some of the peer to peer communication for pipeline
-        parallelism will overlap with computation. Must be False if batch_p2p_comm is true.
-
-    batch_p2p_comm (bool, default=True): Use batch_isend_irecv instead of individual isend/irecv calls. Must be False
-        if overlap_p2p_comm is True.
-
-    batch_p2p_sync (bool, default=True): When using batch_isend_irecv, do a cuda.device.synchronize afterward to work
-        around a bug in older version of PyTorch.
-
-    use_ring_exchange_p2p (bool, default=False): Use custom ring_exchange kernel instead of
-        torch.distributed.batch_isend_irecv(). Requires custom built torch with torch.distributed.ring_exchange.
-
-    deallocate_pipeline_outputs (optional, default=False): If True, output data is deallocated after the tensor is sent
-        to the next pipeline stage.  Helps with saving memory, does nothing when pipeline parallel is not used.
-
-    no_sync_func (optional): Function that creates a context that suppresses asynchronous data-parallel
-        communication. If the model is an instance of core.distributed.DistributedDataParallel, the default is to use
-        core.distributed.DistributedDataParallel.no_sync.
-
-    grad_sync_func (optional): Function that launches asynchronous gradient reductions (e.g. distributed optimizer
-        gradient reduce-scatters). The function should take one argument: an iterable of parameters whose gradients are
-        to be synchronized.
-
-    param_sync_func (optional): Function that launches asynchronous parameter synchronizations (e.g. distributed
-        optimizer parameter all-gathers). The function should take one argument: an iterable of parameters to be
-        synchronized.
-
-    pipeline_model_parallel_split_rank (int, default=None): If int, rank where encoder and decoder should be split in
-        cases where the model has both an encoder and decoder (e.g., T5). Ignored if None.
-
-    barrier_with_L1_time (bool, default=True): If true, use barrier with level 1 time measurements. It is up to the user
-        to make sure calling barrier with their timers will not result in hangs. This can happen if for example the user
-        adds a level 1 timer that is not called by all ranks.

-            first rank of the decoder). This allows the user to set
-            the pipeline parallel size of the encoder and decoder
-            independently. For example, if
-            pipeline_model_parallel_size is 8 and

-            will be the encoder and ranks 3-7 will be the decoder.

-
-        context_parallel_size (int, default = 1):
-            The number of tensor parallel GPU groups to split the
-            network input sequence length across. Compute of attention
-            module requires tokens of full sequence length, so GPUs
-            in a context parallel group need to communicate with each
-            other to exchange information of other sequence chunks.
-            Each GPU and its counterparts in other tensor parallel
-            groups compose a context parallel group.
-
-            For example, assume we have 8 GPUs, if tensor model parallel
-            size is 4 and context parallel size is 2, the network input
-            will be split into two sequence chunks, which are processed
-            by 2 different groups of 4 GPUs. One chunk is processed by
-            GPU0-3, the other chunk is processed by GPU4-7. Four groups
-            are build to do context parallel communications: [GPU0, GPU4],
-            [GPU1, GPU5], [GPU2, GPU6], and [GPU3, GPU7].
-
-            Context parallelism partitions sequence length, so it has no
-            impact on weights, which means weights are duplicated among
-            GPUs in a context parallel group. Hence, weight gradients
-            all-reduce is required in backward. For simplicity, we piggyback
-            GPUs of context parallelism on data parallel group for
-            weight gradient all-reduce.
-
-        nccl_communicator_config_path (str, default = None):
-            Path to the yaml file of NCCL communicator configurations.
-            `min_ctas`, `max_ctas`, and `cga_cluster_size` can be set
-            for each communicator.
-
-    Let's say we have a total of 16 GPUs denoted by g0 ... g15 and we
-    use 2 GPUs to parallelize the model tensor, and 4 GPUs to parallelize
-    the model pipeline. The present function will
-    create 8 tensor model-parallel groups, 4 pipeline model-parallel groups
-    and 8 data-parallel groups as:
-        8 data_parallel groups:
-            [g0, g2], [g1, g3], [g4, g6], [g5, g7], [g8, g10], [g9, g11], [g12, g14], [g13, g15]
-        8 tensor model-parallel groups:
-            [g0, g1], [g2, g3], [g4, g5], [g6, g7], [g8, g9], [g10, g11], [g12, g13], [g14, g15]
-        4 pipeline model-parallel groups:
-            [g0, g4, g8, g12], [g1, g5, g9, g13], [g2, g6, g10, g14], [g3, g7, g11, g15]
-    Note that for efficiency, the caller should make sure adjacent ranks
-    are on the same DGX box. For example if we are using 2 DGX-1 boxes
-    with a total of 16 GPUs, rank 0 to 7 belong to the first box and
-    ranks 8 to 15 belong to the second box.

-    """Retrieves the appropriate forward_backward function given the
-    configuration of parallel_state.
-
-    Returns a function that will perform all of the forward and
-    backward passes of the model given the pipeline model parallel
-    world size and virtual pipeline model parallel world size in the
-    global parallel_state.
-
-    Note that if using sequence parallelism, the sequence length component of
-    the tensor shape is updated to original_sequence_length /
-    tensor_model_parallel_world_size.
-
-    The function returned takes the following arguments:
-
-    forward_step_func (required): A function that takes a data
-        iterator and a model as its arguments and return the model's
-        forward output and the loss function. The loss function should
-        take one torch.Tensor and return a torch.Tensor of loss and a
-        dictionary of string -> torch.Tensor.
-
-        A third argument, checkpoint_activations_microbatch, indicates
-        that the activations for this microbatch should be
-        checkpointed. A None value for this argument indicates that
-        the default from the configuration should be used. This is
-        used when the
-        num_microbatches_with_partial_activation_checkpoints is used.
-
-        For example:
-
-        def loss_func(loss_mask, output_tensor):
-            losses = output_tensor.float()
-            loss_mask = loss_mask.view(-1).float()
-            loss = torch.sum(losses.view(-1) * loss_mask) / loss_mask.sum()
-
-            # Reduce loss for logging.
-            averaged_loss = average_losses_across_data_parallel_group([loss])

-            return loss, {'lm loss': averaged_loss[0]}

-            return output, partial(loss_func, loss_mask)
-
-
-        forward_backward_func(forward_step_func=forward_step, ...)
-
-
-    data_iterator (required): an iterator over the data, will be
-        passed as is to forward_step_func. Expected to be a list of
-        iterators in the case of interleaved pipeline parallelism.
-
-    model (required): the actual model. Expected to be a list of modules in the case of interleaved
-        pipeline parallelism. Must be a (potentially wrapped) megatron_ds.core.models.MegatronModule.
-
-    num_microbatches (int, required):
-        The number of microbatches to go through
-
-    seq_length (int, required): Sequence length of the current global batch. If this is a dual-stack
-        transformer, this is the encoder's sequence length. This is ignored if variable_seq_lengths
-        in the config is True. Otherwise, each microbatch in the current global batch size must use
-        this sequence length.
-
-    micro_batch_size (int, required): The number of sequences in a microbatch.
-
-    decoder_seq_length (int, optional): The sequence length for the decoder in a dual-stack
-        transformer. This is ignored for a single-stack transformer.
-
-    forward_only (optional, default = False): Perform only the forward step
-

-            that clipping is ignored if clip_grad == 0
-        log_num_zeros_in_grad: return number of zeros in the gradients.
-        check_for_nan_in_grad: check if gradients have a NaN.
-        params_have_main_grad: flag indicating if parameters have
-            a `main_grad` field. If this is set, we are assuming
-            that the model parameters are store in the `main_grad`
-            field instead of the typical `grad` field. This happens
-            for the DDP cases where there is a continuous buffer
-            holding the gradients. For example for bfloat16, we want
-            to do gradient accumulation and all-reduces in float32
-            and as a result we store those gradients in the main_grad.
-            Note that main grad is not necessarily in float32.
-        fp16: if true, the model is running in fp16.
-        bf16: if true, the model is running in bfloat16.
-        grad_scaler: used for scaling gradients. Note that this can be
-            None. This case happens when `bf16 = True` and we don't
-            use any loss scale. Note that for `bf16 = True`, we can have
-            a constnat gradient scaler. Also for `bf16 = False`, we
-            always require a grad scaler.
-        models: list of models (i.e., the virtual pipelining models). This

-        Build mapping from param reference to grad buffer shard ranges.
-
-        This method builds a mapping from parameter references to grad
-        buffer shard ranges, specific to each data-parallel (DP) rank's
-        set of 'owned' parameters. Each grad buffer (padded to be an even
-        multiple of DP-world-size) is conceptually divided into DP-world-size
-        contiguous regions, where each DP rank 'owns' a contiguous regions.
-        Ownership in this sense means DP rank is responsible for reducing
-        the relevant subset of grads, and updating the relevant subset of

-
-        This conceptual partitioning of the grad buffer does NOT respect
-        parameter boundaries, and as such it is assumed that each created
-        range references a shard (or subset) of the full parameter. It is
-        easiest to think of each DP rank as operating (i.e., reducing,
-        gathering) purely on views into the grad buffer, for all model-to-
-        main & main-to-model operations.
-
-        This method creates four ranges:
-        - The param's range within the entire grad buffer (i.e., world index).

-        - The param's range within the DP rank's local view of the grad buffer.

+
+    This has the option to accumulate the result of backprop

+    calculation.
+
+    Additionally, the tensor parallel all reduce of the input

+
+    In the case of sequence parallelism, the reduce scatter of the
+    input gradients is done asynchronously with the calcluation of the
+    weight gradients.
+
+    Use of this module requires that the environment variable
+    CUDA_DEVICE_MAX_CONNECTIONS=1. There are a few collective
+    operations, noted in the code, that should be scheduled before
+    compute kernels to overlap the communication with the computation,
+    which is necessary for a speedup but not for correctness so that
+    ordering isn't imposed by the scheduler. Setting
+    CUDA_DEVICE_MAX_CONNECTIONS=1 forces the kernels to be scheduled
+    in the order they are called.

+#         stride: For the strided linear layers.

-Pipeline parallelism for T5
-(Caveat: currently, mcore T5 model has not supported pipeline-parallelism)
-===========================
-
-T5 is a model architecture with both encoder and decoder blocks.
-Consequently, pipeline parallelism is implemented slightly differently
-compared to architectures like GPT and BERT.
-
-In particular, when pipeline_model_parallel_world_size > 1, each stage
-either executes an encoder block or a decoder block. The
---pipeline-model-parallel-split-rank argument controls the rank at which
-the split happens: all ranks lower than this argument execute the
-encoder block, and all ranks equal to or higher than this argument value
-execute the decoder block.
-
-In the encoder section of the model, only one tensor is sent downstream:
-the intermediate encoder_hidden_state. In the decoder section of the
-model, two tensors are sent downstream in the forward pass: the fully
-computed encoder_hidden_state, and the intermediate decoder_hidden_state.
-
-In particular, these are the shapes of the tensors sent between
-different workers:
-    If rank is in decoder section:
-        intermediate decoder_hidden_state (pre-transpose),
-        complete encoder_hidden_state (post-transpose).
-    If rank is at boundary between encoder and decoder sections:
-        complete encoder_hidden_state (post-transpose).
-    If rank is in encoder section:
-        intermediate encoder_hidden_state (pre-transpose).
-
-Additionally, we have code in the backward_step function in schedules.py
-to accumulate the encoder_hidden_state gradient across skip connections
-(encoder_hidden_state fed in as input to each layer in the decoder).

-#
-# However megatron-ds expects its arguments on the command line.
-# And at that point we don't know them.
-#
-# Instead we use Jasons way: we load the arguments form the checkpoint and then override _parse_args to return whatever args we want.
-#
-# If the checkpoint is old, some new arguments may have been introduced and the code will expect these arguments to exist.
-# In order to support this we _first_ parse the arguments normally, and then override them with the arguments from the checkpoint.
-# Keeping the default-value of newer arguments.
-#
-# We then use the megatron deepspeed converter to load the deepspeed checkpoints as if they we're megatron checkpoints.

-# Multi-Stage Prompting for Knowledgeable Dialogue Generation
-
-Below we present the steps to run our multi-stage dialogue prompting (MSDP) framework.
-
-## Multi-Stage Dialogue Prompting
-
-### Data Preparation
-1. Dataset Download: [Wizard of Wikipedia](https://parl.ai/projects/wizard_of_wikipedia/) and [Wizard of Internet](https://parl.ai/projects/sea/)
-2. Data Processing: We provide the script to run the [`data processing`](../../examples/msdp/data_processing.sh) of the datatsets.
-
-### Stage-1: Prompting for Knowledge Generation
-1. We provide the script to perform the [`first-stage prompting`](../../examples/msdp/prompt_knwl_gen.sh) for the knowledge generation.
-2. We provide the [`evaluation script`](../../examples/msdp/eval_knwl_generation.sh) for the automatic evaluation (i.e., F1, BLEU, METEOR, and ROUGE-L) of the knowledge generation.
-
-### Stage-2: Prompting for Response Generation
-1. We provide the script to [`prepare the input file`](../../examples/msdp/prep_resp_gen.sh) for the response generation (based on the previously generated knowledge file).
-2. We provide the script to perform the [`second-stage prompting`](../../examples/msdp/prompt_resp_gen.sh) for the response generation.
-3.  We provide the [`evaluation script`](../../examples/msdp/eval_resp_generation.sh) for the automatic evaluation (i.e., F1, KF1, BLEU, METEOR, and ROUGE-L) of the response generation.

-## End-to-End Training of Neural Retrievers for Open-Domain Question Answering
-
-Below we present the steps to run unsupervised and supervised trainining and evaluation of the retriever for [open domain question answering](https://arxiv.org/abs/2101.00408).
-
-## Retriever Training
-
-#### Unsupervised pretraining
-1. Use `tools/preprocess_data.py` to preprocess the dataset for Inverse Cloze Task (ICT), which we call unsupervised pretraining. This script takes as input a corpus in loose JSON format and creates fixed-size blocks of text as the fundamental units of data. For a corpus like Wikipedia, this will mean multiple sentences per block and multiple blocks per document. Run [`tools/preprocess_data.py`](../../tools/preprocess_data.py) to construct one or more indexed datasets with the `--split-sentences` argument to make sentences the basic unit. We construct two datasets, one with the title of every document and another with the body.
-
-<pre>
-python tools/preprocess_data.py \
-    --input /path/to/corpus.json \
-    --json-keys text title \
-    --split-sentences \
-    --tokenizer-type BertWordPieceLowerCase \
-    --vocab-file /path/to/vocab.txt \
-    --output-prefix corpus_indexed \
-    --workers 10
-</pre>
-
-2. The [`examples/pretrain_ict.sh`](../../examples/pretrain_ict.sh) script runs a single GPU 217M parameter biencoder model for ICT retriever training. Single GPU training is primarily intended for debugging purposes, as the code is developed for distributed training. The script uses a pretrained BERT model and we use a total of batch size of 4096 for the ICT training.

-3. Evaluate the pretrained ICT model using [`examples/evaluate_retriever_nq.sh`](../../examples/evaluate_retriever_nq.sh) for [Google's Natural Questions Open dataset](https://arxiv.org/pdf/1906.00300.pdf).
-
-#### Supervised finetuning
-
-1. Use the above pretrained ICT model to finetune using [Google's Natural Questions Open dataset](https://github.com/google-research/language/tree/master/language/orqa). The script [`examples/finetune_retriever_distributed.sh`](../../examples/finetune_retriever_distributed.sh) provides an example for how to perform the training. Our finetuning process includes retriever score scaling and longer training (80 epochs) on top [DPR training](https://arxiv.org/abs/2004.04906).
-
-2. Evaluate the finetuned model using the same evaluation script as mentioned above for the unsupervised model.
-
-More details on the retriever are available in [our paper](https://arxiv.org/abs/2101.00408).
-
-## Reader Training
-
-The reader component will be available soon.

-# Introduction
-
-This folder is a collection of scripts for converting checkpoints of one training framework (e.g., DeepSpeed) into that of a different framework (e.g., Megatron-LM, HF Transformers).
-
-The folder also contains scripts for inspecting checkpoint files and folders, which could be useful when developing checkpoint conversion logic. At the time of creation, this folder contains scripts to convert DeepSpeed checkpoints to Megatron-LM and HF Transformers checkpoints (this motivated this effort as part of the BigScience project).
-
-Here are the list and details of checkpoint conversions provided by the available scripts:
-
-1. [Megatron-DeepSpeed to Megatron-LM](#Megatron-DeepSpeed-to-Megatron)
-1. [Megatron-DeepSpeed to HF Transformers](#Megatron-DeepSpeed-to-HF-Transformers)
-
-
-## Megatron-DeepSpeed to Megatron
-
-The (current implementation of the) converter extracts args and model parameters from a DeepSpeed checkpoint (i.e., excludes other training states such as optimizer, scheduler, etc) and convert into a Megatron-LM checkpoint similarly containing only model parameters. The converter also provides a best-effort attempt to reshape the tensor-parallelism and pipeline parallelism degrees for the checkpoint. The resulting Megatron-LM checkpoint could be loaded into Megatron-LM framework for finetuning or inference. Tensor parallelism (TP) and pipeline parallelism (PP) are supported in the sense that the generated Megatron-LM checkpoint (folders and files) will be of the same TP and PP of the training that created the input DeepSpeed checkpoint. The entry point of the converter is `deepspeed_to_megatron_ds.py`, which as the following usage:
-```bash
-python tools/convert_checkpoint/deepspeed_to_megatron_ds.py -h
-Convert DeepSpeed Checkpoint to Megatron Checkpoint
-usage: deepspeed_to_megatron_ds.py [-h] [--input_folder INPUT_FOLDER]
-                                [--output_folder OUTPUT_FOLDER]
-                                [--target_tp TARGET_TP]
-                                [--target_pp TARGET_PP] [--for_release]
-
-optional arguments:
-  -h, --help            show this help message and exit
-  --input_folder INPUT_FOLDER
-                        Input DeepSpeed Checkpoint folder
-  --output_folder OUTPUT_FOLDER
-                        Output Megatron checkpoint folder
-  --target_tp TARGET_TP
-                        Target TP degree
-  --target_pp TARGET_PP
-                        Target PP degree
-  --for_release         Convert for release purpose, reset some (progress)
-                        counters.
-```
-
-The following scripts which proved useful for debugging are also included:
-1. `inspect_deepspeed_checkpoint.py`: view the contents of a DeepSpeed checkpoint folder.
-2. `inspect_checkpoint.py`: view the contents of a PyTorch checkpoint file.
-
-## Megatron-DeepSpeed to HF Transformers
-
-In order to convert from Megatron-DeepSpeed to HF Transformers, you can do this directly using:
-
-```bash
-python tools/convert_checkpoint/deepspeed_to_transformers.py  \
---input_folder /path/to/Megatron-Deepspeed/checkpoint/global_step97500 \
---output_folder /path/to/transformers/checkpoint
-```
-since `transformers` currently only works with PP=1/TP=1 we use the defaults `--target_tp 1 --target_pp 1`.
-
-The script taps into `transformers` and as of this writing requires `transformers@master` (or `transformers==4.11` if you read this later and a new version is released).
-
-Note that you may run into problems with not having `megatron_ds.enums` defined since `Megatron-Deepspeed` in the `bigscience-workshop` tree diverged from the `microsoft` tree. In such cases you can fix this on the fly by ensuring the former appears first in the `sys.path`. For example:
-
-
-```bash
-PYTHONPATH=/hf/Megatron-DeepSpeed-bigscience:/hf/Megatron-DeepSpeed-microsoft \
-python tools/convert_checkpoint/deepspeed_to_transformers.py  \
---input_folder /path/to/Megatron-Deepspeed/checkpoint/global_step97500 \
---output_folder /path/to/transformers/checkpoint
-```
-
-Alternatively, you can convert first from Megatron-DeepSpeed to Megatron and then to HF Transformers:
-
-```bash
-# 1. Megatron-DeepSpeed to Megatron
-cd /hf/Megatron-DeepSpeed-bigscience
-python tools/convert_checkpoint/deepspeed_to_megatron_ds.py --target_tp 1 --target_pp 1 \
---input_folder /path/to/Megatron-Deepspeed/checkpoint/global_step97500 \
---output_folder /path/to/Megatron/checkpoint
-
-# 2. Megatron to HF Transformers
-cd /hf/transformers
-python src/transformers/models/megatron_gpt2/convert_megatron_gpt2_checkpoint.py \
-/path/to/Megatron/checkpoint/iter_0097500/mp_rank_00/model_optim_rng.pt
-```

-The following steps show how to prepare training dataset to train the mode.
-
-# Libraries to install
-
-```
-    pip install ftfy langdetect numpy torch pandas nltk sentencepiece boto3 tqdm regex bs4 newspaper3k htmlmin tldextract 
-    git clone https://github.com/mattilyra/LSH
-    cd LSH
-    python setup.py install
-``` 
-
-# Download the dataset
-
-1. Download the deduplicated URLs from [jcpeterson](https://mega.nz/#F!EZZD0YwJ!9_PlEQzdMVLaNdKv_ICNVQ!cc4RgQQZ)
-2. Remove blacklisted URLs.
-```
-python blacklist_urls.py <path to the dowloaded deduplicated URLs> <filename for clean urls. e.g. clean_urls.txt>
-```
-3. Download the content from the clean urls with [openwebtext's utilities](https://github.com/eukaryote31/openwebtext/blob/master/download.py). 
-
-4. Merge the contents into one loose json file with 1 json per newline of the format `{'text': text, 'url': unique_url}`. It is important for the url to be unique.
-
-# Prepare the data for GPT training:
-
-1. Perform ftfy, english detection and remove documents with less than 128 tokens. This step can be sharded and run on shards.
-```
-python cleanup_dataset.py <input data file> <output cleaned data filename>
-```
-Additional cleanup (e.g. remove documents less than 512 characters or dataset specific cleaning like stories, realnews datasets) can be done using `cleanup_fix_dataset.py`. More details can be found by running `python cleanup_fix_dataset.py --help`.
-2. Using LSH, find possible duplicates and store then in a file for later processing. The code supports saving and loading fingerprints for recurrent deduplications, and is also multithreaded for faster processing. More details are can be found by `python find_duplicate.py --help`.
-```
-python find_duplicates.py --inputs <pairlist list of input cleaned data files and keys, e.g. cc.json cc_id news.json news_id> --output <output possible duplicate urls filename>
-```
-3. Based on similarity measure defind inside function `is_similar` (default: 0.9), group urls that are similar. Basically, for each group, only one url we should keep and remove the rest.
-```
-python group_duplicate_urls.py <possible duplicate urls file> <output file containing similar urls>
-```
-4. Remove similar documents that were detected in the last step.
-```
-python remove_group_duplicates.py <file containing simialr documents> <cleaned data file> <outputfile containing deduplicate data>
-```
-
-5. Shuffle the dataset.
-```
-shuf <cleaned deduped data file> -o train_data.json
-```
-
-# Deduplicating ngrams
-
-To deduplicate the downstream tasks (e.g. lambada, squad) from the training dataset, we run the following command.
-
-```
-python filter_ngrams.py --tasks <name of the task, e.g. lambada, squad> --dedup-dataset <training dataset to deduplicate> <json key> --output <output training dataset>
-```
-We use 13-grams by default for the deduplication. When we find a 13-gram match in a training document, we split the document into two pieces and remove the 13-gram along with 200 characters from the both side of the 13-gram. We also remove any splitted document with less than 200 characters or if a document got splitted more than 10 times. These parameters can be changed using corresponding arguments.
-
-Only for the lambada task, we need to provide the path, `--lambada-path <path of the lambada test data>`.
-
-Several other features (e.g. save and load dictionary) have been added, look at `python filter_ngrams.py --help` for details.

-This directory contains a collection of tools for building the retrieval database and pretraining neighbors for Retro. This preprocessing pipeline is broken into 3 main stages:
-
-1. **Build retrieval chunk database** : Used for retrieving neighbors and continuation chunks, which are then passed through the retrieval encoder.
-2. **Build index for similarity search** : Train and build a search index for querying chunk neighbors.
-3. **Query pretraining neighbors** : For matching pretraining samples to database chunks. Neighbors are generated separately for training, validation, and test datasets.
-
-The following overview goes into more detail on the pipeline, code structure, usage, and pretraining.

-# Quick start
-
-See `examples/get_preprocess_cmd.sh` for example arguments.
-
-Key files:
-
-- `main.py` : Entry point.
-- `examples/get_preprocess_cmd.sh` : Build preprocessing command (for `main.py`).
-- `examples/preprocess_data.sh` : Run preprocessing (calls `get_preprocess_cmd.sh`, `main.py`).
-
-Use `--retro-tasks` to move through the preprocessing pipeline.
-
-- Simplest setup (builds everything): `--retro-tasks build`
-- Alternatively, for tuning compute resources, run stages independently:
-  - Build retrieval database: `--retro-tasks db-build`
-  - Build search index: `--retro-tasks index-build`
-  - Query neighbors: `--retro-tasks pretraining-query-neighbors`
-
-Sample code flow:
-
-- `main.py` : Entry point (e.g., using `--retro-tasks X`).
-- `db/build.py` : Build retrieval database.
-- `index/build.py` : Build search index. Calls the following two files:
-  - `index/train.py` : Train index on subset of database.
-  - `index/add.py` : Add database chunks to index.
-- `pretraining/query.py` : Query pretraining samples for database neighbors (saved to disk and used during pretraining).
-
-<!-- ################ stages ################ -->
-# Stages
-
-### Build retrieval chunk database
-
-This *database* (stored as a 2-D array, NOT a relational database) consists of a list of chunks (traditionally length 64) extracted from the original GPT token dataset. This is simply a consecutive, non-overlapping chunking of the token dataset. Chunking only takes place within a document, and therefore the final chunk of each document has length: 1 <= chunk_length <= max_chunk_length.
-
-We discard chunks that would convert to an empty Bert sequence (rare case, happens ~1/100,000 chunks in our case), since we use Bert embeddings for building our index. Thus, the total number of chunks in the database will be slightly less than a naive calculation.
-
-### Build index for similarity search
-
-To match pretraining chunks to database chunks, a search index must be built to perform this querying. We use Faiss (https://github.com/facebookresearch/faiss) for training and building this index. Generally, the index is trained on a subset of all chunks in the database (specified via `--retro-nchunks-sampled`). After training, all chunks are added into the index, to be available during querying.
-
-Indexes only accept 1-D floating point vectors for training and adding, so each chunk must first be embedded before passing to the index for either training or adding. We use Bert embeddings for this purpose, and the embeddings are generated automatically within the pipeline.
-
-### Query pretraining neighbors
-
-To ensure fast Retro pretraining, the database neighbors for pretraining samples are pre-computed and saved to disk, for efficient access within the Retro dataset. In this stage, the pretraining datasets (training, validation, and test) are iterated, each sample is broken into chunks, and the chunks are used for querying the index. Similar to when building the index, each chunk is embedded (via Bert) before querying the index.
-
-The saved neighbors are labeled with unique dataset properties (i.e., seed, sequence length, number of samples, etc.) to ensure the neighbors generated during preprocessing match the neighbors requested during pretraining.
-
-<!-- ################ code structure ################ -->
-# Code structure
-
-### `tools/retro/main.py`
-
-This is the main entry point for Retro preprocessing. Call `main.py --help` to see arguments. Additionally, some Retro arguments are in Megatron's core arguments, so also see `add_retro_args()` section of `megatron/arguments.py` for additional arguments. Two of the most important arguments to customize are `--retro-workdir` and `--retro-tasks`.
-
-- **`--retro-workdir`** : Set the directory in which the preprocessing pipeline saves its datasets and configuration files. This argument should remain consistent for a full pass through the pipeline, and for pretraining.
-
-- **`--retro-tasks`** : Set the stages of preprocessing to perform. As mentioned previously, the three high-level stages are: 1) build retrieval database, 2) build search index, and 3) query pretraining neighbors. `--retro-tasks` can be used to either run the full pipeline, or run each of these stages in isolation. The latter case is useful for tuning compute resources for each stage. For example, index training utilizes GPUs and requires relatively less time, while querying neighbors uses the CPU and is a relatively slow process. Example tasks include:
-
-  - **`--retro-tasks build`** : Run entire preprocessing pipeline.
-  - **`--retro-tasks db-build`** : Build retrieval database.
-  - **`--retro-tasks index-build`** : Train and build search index.
-  - **`--retro-tasks pretraining-query-neighbors`** : Query pretraining neighbors.
-
-Multiple tasks can be specified by separating with commas (e.g., `--retro-tasks db-build,index-build`). Additionally, various 'miscellaneous' tasks are currently including, primarily for validating data for each stage; these task names can be seen in `main.py`.
-
-### `tools/retro/examples`
-
-Example scripts for setting arguments and launch Retro preprocessing. The key files here are:
-
-- **`get_preprocess_cmd.sh`** : Sets up arguments and command for preprocessing. **Important note**: this script assumes a few environment variables are already set before it is called. Please see the `Environment vars.` section at the top of this file. Generally, environment variables must be set to determine the location of Retro workdirs, input datasets, and GPT and Bert model information.
-- **`preprocess_data.sh`** : Calls `get_preprocess_cmd.sh` to get arguments, and then calls `main.py` to launch preprocessing.
-- **`pretrain_model.sh`** : Example script for pretraining on Wikipedia data, after preprocessing is complete.
-
-### `tools/retro/db`
-
-Build the retrieval chunk database. The key files here are:
-
-- **`build.py`** : Entry point for building the database. This code is responsible for iterating the input datasets (i.e., `--data-path`), parsing each dataset into consecutive chunks, checking for empty Bert (Wordpiece) conversions, and storing this information to disk. Two databases are created: 1) the retrieval database, and 2) a sampled database used for training the search index.
-- **`dataset.py`** : Defines database class, for iterating or accessing chunks in the database. Each chunk contains its tokens, Bert conversion length, and dataset index.
-
-Input data:
-
-<!-- - Token datasets, as generated by `tools/preprocess_data.py`. Each dataset should include a `.bin` and `.idx` file. Multiple datasets can be specified by using a blended configuration (see `--data-path` in `megatron/arguments.py`). -->
-- Token datasets, as loaded by `gpt_dataset.py`. Multiple datasets can be specified by using a blended configuration (see `--data-path` in `megatron/arguments.py`).
-
-Output data:
-
-- **`<RETRO_WORKDIR>/db/merged/train.hdf5`** : The main retrieval database. (*Database* here is used to denote a list of indexed chunks, rather than a *relational database*.) The chunks in this database are added to the search index, and are used for retrieval during pretraining. This file contains a single dataset `'chunks'`, which contains 5 columns:
-
-  - `dataset_idx` : Dataset index, from list of blended indexed datasets.
-  - `document_idx` : Document index within dataset.
-  - `chunk_start_idx` : Chunk's starting token index within document.
-  - `chunk_end_idx` : Chunk's ending token index (exclusive) within document.
-  - `bert_chunk_length` : Length of Bert token sequence, after converting from GPT.
-
-- **`<RETRO_WORKDIR>/db/merged/sampled.hdf5`** : Subset of training database that is used for training the search index. This file has the same structure as detailed above. In general, this database is significanly smaller than the `train.hdf5` database, since the search index only needs a relatively small number of samples to understand the data's structure. After training, all chunks in the main database (`train.hdf5`) are *added* to the search index.
-
-### `tools/retro/index`
-
-Build the search index. The key files here are:
-
-- `build.py` : Entry point for building the search index. First, the index is trained on the sampled chunk database (see above) by calling `train.py`, and then all chunks for the full database are added to the index by calling `add.py`. Note that training requires first embedding (using Bert) all chunks (a parallel operation), and then loading these embeddings and training the index (a sequential operation), so it's best to change one's compute setup after all chunks have been embedded and saved to disk.
-- `indexes/faiss_base.py` : Wrapper class for building a Faiss index, following the standard `train()` and `add()` operations.
-- `indexes/faiss_par_add.py` : Similar to above, except it uses an embarrassingly parallel (multi-node, multi-process) `add()` operation. Vectors are first added to separate index copies, and then merged together.
-
-Input data:
-
-- **`<RETRO_WORKDIR>/db/merged/sampled.hdf5`** : Chunks used for training the search index.
-- **`<RETRO_WORKDIR>/db/merged/train.hdf5`** : Chunks used for adding to the *trained* search index.
-
-Output data:
-
-- **`<RETRO_WORKDIR>/index/<RETRO_INDEX_TYPE>/<RETRO_INDEX_STR>/added.faissindex`** : The final index, which has been trained and has had all database chunks added to it. This index is ready for querying neighbors. Here, `RETRO_INDEX_TYPE` and `RETRO_INDEX_STR` correspond to the same-name arguments `--retro-index-type` (e.g., `faiss-par-add`) and `--retro-index-str` (e.g., `OPQ32_256,IVF4194304_HNSW32,PQ32`).
-- **`<RETRO_WORKDIR>/index/<RETRO_INDEX_TYPE>/<RETRO_INDEX_STR>/empty.faissindex`** : Generally can be discarded once `added.faissindex` has been built, but this file contains the *post-training*, *pre-adding* index. Useful for debugging or building other indexes.
-
-### `tools/retro/pretraining`
-
-Query the pretraining datasets (training, validation, test) for their neighbors within the database. Neighbors are queried during preprocessing -- rather than during pretraining -- because querying is a fairly slow operation, so it would be a bottleneck if performed during pretraining. Queried neighbors are tagged with their unique identifying information (e.g., `train_indexmap_27662746ns_2048sl_1234s`), so as to avoid incorrect references during pretraining. The key files here are:
-
-- **`query.py`** : Entry point for querying. The pretraining datasets are iterated, and each chunk within each sample is queried using the search index. These neighbors are filtered by discarding any database chunks that fall within the same document as any chunk within a pretraining sample.
-- **`chunk_dataset.py`** : This creates an iterable 'chunk' dataset form of a pretraining dataset. This is just a light wrapper, but makes it easier to deterministically iterate and assign IDs to each chunk in a sample dataset.
-- **`retro_dataset.py`** : The Retro dataset used for pretraining (not used in preprocessing). Each sample returns the sample tokens, along with neighbor tokens for each chunk within the sample.
-
-Input data:
-
-- Token datasets, as loaded by `gpt_dataset.py`.
-- **`<RETRO_WORKDIR>/index/<RETRO_INDEX_TYPE>/<RETRO_INDEX_STR>/added.faissindex`** : The trained index, with all database chunks added to it (see previous section for details).
-
-Output data:
-
-- **`<RETRO_WORKDIR>/{train,valid,test}_XXns_YYsl_ZZs/WW.hdf5`** : These directories/files contain the indexes of neighbors for each chunk within each sample of the pretraining datasets. Each directory (e.g., `train_indexmap_2047435ns_2048sl_1234s`) contains a list of HDF5 files (e.g., one file might be called `0075700000-0075800000.hdf5`). Each HDF5 file contains a consecutive subset of neighbor IDs for a given chunk, for indexing into the main retrieval database. All HDF5 files taken together within a given directory, represent the entire set of neighbors for a dataset. The size of these HDF5 files is determined by the argument `--retro-block-size`. The `XX`, `YY`, `ZZ`, `WW` notation above denotes the dataset properties that are used for uniquely tagging the neighbor files, to ensure compatibility during model pretraining. These neighbor files are ultimated used by `retro_dataset.py` during pretraining, for building Retro samples.
-
-### `tools/retro/cli`
-
-Inspect preprocessed data. To use the CLI, open a Python terminal via the `python` command, and then load a Retro workdir with the following:
-
-```
-from tools.retro.cli import retro
-retro.init("/path/to/retro/workdir")
-```
-
-This initializes Megatron, and prepares the Retro data for inspection. See the printed usage for available functions. Several routines are included for viewing data in the retrieval database and viewing pretraining samples and neighbors. For example:
-
-```python
-retro.get_db_num_indexed_datasets() # 15
-retro.get_db_chunk_text(92874113) # 'research project at ...  and philosophy'
-retro.get_pt_sample('train', 62005) # '[16084, 26158, 25387 ..., 6898, 9568]'
-```
-
-Most methods within the CLI are prefixed to denote the data being inspected:
-
-- **'db'** : Retrieval database (i.e., chunk tokens, document IDs, and dataset IDs)
-- **'pt'** : Pretraining datasets (i.e., sample tokens and neighbor tokens)
-
-### `tools/retro/utils.py`
-
-A collection of utility methods. Most importantly, this contains:
-
-- **`def get_gpt_tokenizer()`** : Get the GPT tokenizer.
-- **`def get_bert_tokenizer()`** : Get the Bert tokenizer.
-- **`class GPTToTextDataset`** : Wrapper class that converts GPT (BPE) samples to raw text.
-
-### `tools/bert_embedding`
-
-Generate Bert embeddings. The main files here are:
-
-- **`embed.py`** : Entry point for generating embeddings, and contains the two main embedding classes, `BertEmbedder` and `DiskDataParallelBertEmbedder` (more below). This file contains code for generating Megatron embeddings, while the file below contains code for Huggingface embeddings.
-- **`huggingface.py`** : Used by `embed.py` when the embedder is configured (see below) to output Huggingface embeddings.
-- **`dataset.py`** : Wrapper class for converting a raw-text dataset to Bert (Wordpiece) tokens.
-
-The Bert embeddings can be configured along two axes. The first axis is the output type:
-
-- **`class BertEmbedder`** : This class takes a raw-text dataset as input, generates its embeddings, and returns a Numpy array. The main functions are `embed_text_dataset` (accepts a raw-text dataset) and `embed_text` (accepts a string).
-- **`class DiskDataParallelBertEmbedder`** : This class wraps `BertEmbedder`, and rather than returning a Numpy array, it saves the embeddings to disk. Additionally, this class automatically splits data across data parallel ranks (using interleaving), and also processes data in a specified `block_size` (e.g., 1,000,000).
-
-The second axis is the type of embedding model to use, controlled by the argument `--bert-embedder-type`:
-
-- **`--bert-embedder-type megatron`** : Use Megatron's Bert model. The specific model used is dependent on the loaded checkpoint, vocab file, and tokenizer.
-- **`--bert-embedder-type huggingface`** : Use Huggingface's `bert-large-cased`. (*Note*: Huggingface's inclusion is likely to be deprecated; and there is no ability to configure cased/uncased.)
-
-### Pretraining
-
-- **`pretrain_retro.py`** : Launch script for pretraining Retro. Similar to `pretrain_gpt.py`, except this script handles loading neighbor tokens and setting up the neighbor attention mask.
-<!-- - `megatron/data/gpt_dataset.py` : ? -->
-- **`megatron/model/retro_transformer.py`** : Implementation of Retro model, including the main transformer, the retrieval encoder, and chunked cross-attention layers. Note that currently, `retro_transformer.py` contains several classes that are nearly identical to `transformer.py`, except for 1 or 2 lines, due to code changes that are yet to be integrated.
-- **`tools/retro/pretraining/retro_dataset.py`** : The Retro dataset used for pretraining (not used in preprocessing). Each sample returns the sample tokens, along with neighbor tokens for each chunk within the sample.
-
-
-<!-- ################ arguments ################ -->
-# Arguments
-
-See `tools/retro/main.py`'s `add_retro_args()` and `megatron/arguments.py`'s `_add_retro_args()` for details and descriptions. Here we list some particularly important arguments:
-
-- `--retro-workdir` : Mentioned previously, this argument determines the directory in which a set of Retro data is stored (during preprocessing) and loaded (during pretraining). Any change in this directory during preprocessing may result in preprocessing starting over from scratch, and any change before pretraining will result in pretraining throwing an error.
-- Preprocessing
-  - `--retro-gpt-chunk-length` : Retro chunk length (e.g., 64 in original paper).
-  - `--retro-tasks` : Comma-separated list of preprocessing tasks. Generally, the `build` task is the simplest way to run the preprocessing pipeline. For finer control, individual stages can be run by using tasks (in order): `db-build`, `index-build`, and `pretraining-query-neighbors`.
-  - `--retro-index-str` : Faiss index string that defines the index configuration. This will vary based on data size, compute/disk setup, and user needs. For example, this string looks something like `IVF262144_HNSW32,Flat` or `OPQ32_256,IVF4194304_HNSW32,PQ32`.
-- Pretraining
-  - `--retro-add-retriever` : Must be used to select Retro model.
-  - `--retro-num-neighbors` : Number of neighbors to retrieve from the retrieval database (defaults to 2).
-  - `--retro-num-retrieved-chunks` : For each neighbor, the number consecutive chunks to retrieve, including the initial neighbor (defaults to 2).
-
-<!-- ################ pretraining ################ -->

-#     database, search index, and pretraining neighbors.
-# - RETRO_TASKS : One of 'build', 'db-build', 'index-build', or

-################ Retro tasks. ################
-# The '--retro-tasks' argument is a comma-separated list of tasks to run, in
-# sequential order. For a quick start, simply set this to 'build' to run the
-# entire preprocessing pipeline. For finer control, you may specify the list of
-# tasks to run. This is desirable for tuning computational resources. For
-# example, training the search index is relatively fast and utilizes GPUs,
-# while querying the search index is relatively slow, CPU-only, and memory
-# intensive (i.e., multiple populated search indexes are loaded simultaneously).
-
-# *Note* : Once the task(s) below have been completed -- by running either
-#    1) 'build', or 2) the sequential combination of 'db-build', 'index-build',
-#    and 'pretraining-query-neighbors' -- we are ready to pretrain Retro by
-#    calling pretrain_retro.py.
-
-# ---- Option #1 : Run entire pipeline. ----
-
-# RETRO_TASKS="build" # (*note*: default tasks)
-
-# ---- Option #2 : Run specific stages. ----
-# *Note*: Run the following stages in the given order. Optionally, tune your
-#   cluster setup for each stage, as described above.
-
-# RETRO_TASKS="db-build" # ....................... run 1st
-# RETRO_TASKS="index-build" # .................... run 2nd
