Training a model with Megatron-LM for ROCm
******************************************
.. caution::
This documentation does not reflect the latest version of ROCm Megatron-LM
training performance documentation. See :doc:`../megatron-lm` for the latest version.
The `Megatron-LM framework for ROCm <https://github.com/ROCm/Megatron-LM>`_ is
a specialized fork of the robust Megatron-LM, designed to enable efficient
training of large-scale language models on AMD GPUs. By leveraging AMD
Instinct™ MI300X Series GPUs, Megatron-LM delivers enhanced
scalability, performance, and resource utilization for AI workloads. It is
purpose-built to support models like Llama, DeepSeek, and Mixtral,
enabling developers to train next-generation AI models more
efficiently.
AMD provides a ready-to-use Docker image for MI300X Series GPUs containing
essential components, including PyTorch, ROCm libraries, and Megatron-LM
utilities. It contains the following software components to accelerate training
workloads:
+--------------------------+--------------------------------+

.. note::
Some models, such as Llama, require an external license agreement through
a third party (for example, Meta).
.. _amd-megatron-lm-performance-measurements-v255:
Performance measurements
========================
To evaluate performance, the
`Performance results with AMD ROCm software <https://www.amd.com/en/developer/resources/rocm-hub/dev-ai/performance-results.html#tabs-a8deaeb413-item-21cea50186-tab>`__
page provides reference throughput and latency measurements for training
popular AI models.
.. important::
The performance data presented in
`Performance results with AMD ROCm software <https://www.amd.com/en/developer/resources/rocm-hub/dev-ai/performance-results.html>`__
only reflects the latest version of this training benchmarking environment.
The listed measurements should not be interpreted as the peak performance achievable by AMD Instinct MI325X and MI300X GPUs or ROCm software.
System validation
=================
Before running AI workloads, it's important to validate that your AMD hardware is configured
correctly and performing optimally.
If you have already validated your system settings, including aspects like NUMA auto-balancing, you
can skip this step. Otherwise, complete the procedures in the :ref:`System validation and
optimization <rocm-for-ai-system-optimization>` guide to properly configure your system settings
before starting training.
To test for optimal performance, consult the recommended :ref:`System health benchmarks
<rocm-for-ai-system-health-bench>`. This suite of tests will help you verify and fine-tune your
system's configuration.
.. _mi300x-amd-megatron-lm-training-v255:
Environment setup
=================
Use the following instructions to set up the environment, configure the script to train models, and

Network interface
-----------------
Update the network interface in the script to match your system's network interface. To
find your network interface, run the following (outside of any Docker container):
.. code-block:: bash
ip a
Look for an active interface that has an IP address in the same subnet as
your other nodes. Then, update the following variables in the script, for
example:
.. code-block:: bash
export NCCL_SOCKET_IFNAME=ens50f0np0
export GLOO_SOCKET_IFNAME=ens50f0np0
.. _amd-megatron-lm-tokenizer-v255:
Tokenizer
---------
You can assign the path of an existing tokenizer to the ``TOKENIZER_MODEL`` as shown in the following examples.
If the tokenizer is not found, it'll be downloaded if publicly available.
.. container:: model-doc pyt_megatron_lm_train_llama-3.3-70b
If you do not have Llama 3.3 tokenizer locally, you need to use your
personal Hugging Face access token ``HF_TOKEN`` to download the tokenizer.
See `Llama-3.3-70B-Instruct
<https://huggingface.co/meta-llama/Llama-3.3-70B-Instruct>`_. After you are
authorized, use your ``HF_TOKEN`` to download the tokenizer and set the
variable ``TOKENIZER_MODEL`` to the tokenizer path.
.. code-block:: shell
export HF_TOKEN=<Your personal Hugging Face access token>
The training script uses the ``HuggingFaceTokenizer``. Set ``TOKENIZER_MODEL`` to the appropriate Hugging Face model path.
.. code-block:: shell
TOKENIZER_MODEL="meta-llama/Llama-3.3-70B-Instruct"
.. container:: model-doc pyt_megatron_lm_train_llama-3.1-8b
The training script uses the ``HuggingFaceTokenizer``. Set ``TOKENIZER_MODEL`` to the appropriate Hugging Face model path.
.. code-block:: shell
TOKENIZER_MODEL="meta-llama/Llama-3.1-8B"
.. container:: model-doc pyt_megatron_lm_train_llama-3.1-70b
The training script uses the ``HuggingFaceTokenizer``. Set ``TOKENIZER_MODEL`` to the appropriate Hugging Face model path.
.. code-block:: shell
TOKENIZER_MODEL="meta-llama/Llama-3.1-70B"
.. container:: model-doc pyt_megatron_lm_train_llama-2-7b pyt_megatron_lm_train_llama-2-70b
The training script uses either the ``Llama2Tokenizer`` or ``HuggingFaceTokenizer`` by default.
.. container:: model-doc pyt_megatron_lm_train_deepseek-v3-proxy
The training script uses the ``HuggingFaceTokenizer``. Set ``TOKENIZER_MODEL`` to the appropriate Hugging Face model path.
.. code-block:: shell
TOKENIZER_MODEL="deepseek-ai/DeepSeek-V3"
.. container:: model-doc pyt_megatron_lm_train_deepseek-v2-lite-16b
The training script uses the ``HuggingFaceTokenizer``. Set ``TOKENIZER_MODEL`` to the appropriate Hugging Face model path.
.. code-block:: shell
TOKENIZER_MODEL="deepseek-ai/DeepSeek-V2-Lite"
.. container:: model-doc pyt_megatron_lm_train_mixtral-8x7b pyt_megatron_lm_train_mixtral-8x22b-proxy
Download the Mixtral tokenizer.
.. code-block:: shell
mkdir tokenizer
cd tokenizer
export HF_TOKEN=<Your personal Hugging Face access token>
wget --header="Authorization: Bearer $HF_TOKEN" -O ./tokenizer.model https://huggingface.co/mistralai/Mixtral-8x7B-v0.1/resolve/main/tokenizer.model
Use the ``HuggingFaceTokenizer``. Set ``TOKENIZER_MODEL`` to the appropriate Hugging Face model path.
.. code-block:: shell
TOKENIZER_MODEL=tokenizer/tokenizer.model
Dataset options
---------------
You can use either mock data or real data for training.
* Mock data can be useful for testing and validation. Use the ``MOCK_DATA`` variable to toggle between mock and real data. The default
value is ``1`` for enabled.
.. code-block:: bash
MOCK_DATA=1
* If you're using a real dataset, update the ``DATA_PATH`` variable to point to the location of your dataset.
.. code-block:: bash
MOCK_DATA=0
DATA_PATH="/data/bookcorpus_text_sentence" # Change to where your dataset is stored
Ensure that the files are accessible inside the Docker container.
Download the dataset
^^^^^^^^^^^^^^^^^^^^
.. container:: model-doc pyt_megatron_lm_train_llama-3.3-70b pyt_megatron_lm_train_llama-3.1-8b pyt_megatron_lm_train_llama-3.1-70b pyt_megatron_lm_train_llama-2-7b pyt_megatron_lm_train_llama-2-70b
For Llama models, use the `prepare_dataset.sh
<https://github.com/ROCm/Megatron-LM/tree/rocm_dev/examples/llama>`_ script
to prepare your dataset.
To download the dataset, set the ``DATASET`` variable to the dataset you'd
like to use. Three datasets are supported: ``DATASET=wiki``, ``DATASET=fineweb``, and
``DATASET=bookcorpus``.
.. code-block:: shell
DATASET=wiki TOKENIZER_MODEL=NousResearch/Llama-2-7b-chat-hf bash examples/llama/prepare_dataset.sh #for wiki-en dataset
DATASET=bookcorpus TOKENIZER_MODEL=NousResearch/Llama-2-7b-chat-hf bash examples/llama/prepare_dataset.sh #for bookcorpus dataset
``TOKENIZER_MODEL`` can be any accessible Hugging Face tokenizer.
Remember to either pre-download the tokenizer or setup Hugging Face access
otherwise when needed -- see the :ref:`Tokenizer <amd-megatron-lm-tokenizer-v255>` section.
.. note::
When training set ``DATA_PATH`` to the specific file name prefix pointing to the ``.bin`` or ``.idx``
as in the following example:
.. code-block:: shell
DATA_PATH="data/bookcorpus_text_sentence" # Change to where your dataset is stored.
.. container:: model-doc pyt_megatron_lm_train_deepseek-v3-proxy
If you don't already have the dataset, download the DeepSeek dataset using the following
commands:

Ensure that the files are accessible inside the Docker container.
Multi-node configuration
------------------------
If you're running multi-node training, update the following environment variables. They can
also be passed as command line arguments. Refer to the following example configurations.
* Change ``localhost`` to the master node's hostname:
.. code-block:: shell
MASTER_ADDR="${MASTER_ADDR:-localhost}"
* Set the number of nodes you want to train on (for instance, ``2``, ``4``, ``8``):
.. code-block:: shell
NNODES="${NNODES:-1}"
* Set the rank of each node (0 for master, 1 for the first worker node, and so on):
.. code-block:: shell
NODE_RANK="${NODE_RANK:-0}"
* Set ``DATA_CACHE_PATH`` to a common directory accessible by all the nodes (for example, an
NFS directory) for multi-node runs:
.. code-block:: shell
DATA_CACHE_PATH=/root/cache # Set to a common directory for multi-node runs
* For multi-node runs, make sure the correct network drivers are installed on the nodes. If
inside a Docker container, either install the drivers inside the Docker container or pass the network
drivers from the host while creating the Docker container.
.. code-block:: shell
# Specify which RDMA interfaces to use for communication
export NCCL_IB_HCA=rdma0,rdma1,rdma2,rdma3,rdma4,rdma5,rdma6,rdma7
Getting started
===============
The prebuilt Megatron-LM with ROCm training environment allows users to quickly validate
system performance, conduct training benchmarks, and achieve superior
performance for models like Llama, DeepSeek, and Mixtral. This container should not be
expected to provide generalized performance across all training workloads. You
can expect the container to perform in the model configurations described in
the following section, but other configurations are not validated by AMD.
.. _amd-megatron-lm-run-training-v255:
Run training
------------
Use the following example commands to set up the environment, configure
:ref:`key options <amd-megatron-lm-benchmark-test-vars-v255>`, and run training on

Multi-node training
^^^^^^^^^^^^^^^^^^^
To run training on multiple nodes, launch the Docker container on each node.
For example, for Llama 3 using a two node setup (``NODE0`` as the master node),
use these commands.
* On the master node ``NODE0``:
.. code-block:: shell
TEE_OUTPUT=1 MBS=2 BS=256 TP=1 TE_FP8=1 SEQ_LENGTH=8192 MODEL_SIZE=8 MASTER_ADDR=IP_NODE0 NNODES=2 NODE_RANK=0 bash examples/llama/train_llama3.sh
* On the worker node ``NODE1``:
.. code-block:: shell
TEE_OUTPUT=1 MBS=2 BS=256 TP=1 TE_FP8=1 SEQ_LENGTH=8192 MODEL_SIZE=8 MASTER_ADDR=IP_NODE0 NNODES=2 NODE_RANK=1 bash examples/llama/train_llama3.sh
Or, for DeepSeek-V3, an example script ``train_deepseek_v3_slurm.sh`` is
provided in
`<https://github.com/ROCm/Megatron-LM/tree/rocm_dev/examples/deepseek_v3>`__ to
enable training at scale under a SLURM environment. For example, to run
training on 16 nodes, try the following command:
.. code-block:: shell
sbatch examples/deepseek_v3/train_deepseek_v3_slurm.sh
.. _amd-megatron-lm-benchmark-test-vars-v255:
Key options
-----------
The benchmark tests support the following sets of variables.
``TEE_OUTPUT``
``1`` to enable training logs or ``0`` to disable.
``TE_FP8``
``0`` for B16 or ``1`` for FP8 -- ``0`` by default.
``GEMM_TUNING``
``1`` to enable GEMM tuning, which boosts performance by using the best GEMM kernels.
``USE_FLASH_ATTN``
``1`` to enable Flash Attention.
``FSDP``
``1`` to enable PyTorch FSDP2. If FSDP is enabled, ``--use-distributed-optimizer``,
``--overlap-param-gather``, and ``--sequence-parallel`` are automatically disabled.
``ENABLE_PROFILING``
``1`` to enable PyTorch profiling for performance analysis.
``transformer-impl``
``transformer_engine`` to use the Transformer Engine (TE) or ``local`` to disable TE.
``MODEL_SIZE``
``8B`` or ``70B`` for Llama 3 and 3.1. ``7B`` or ``70B`` for Llama 2, for example.
``TOTAL_ITERS``
The total number of iterations -- ``10`` by default.
``MOCK_DATA``
``1`` to use mock data or ``0`` to use real data you provide.
``MBS``
Micro batch size.
``BS``
Global batch size.
``TP`` / ``TP_SIZE``
Tensor parallel (``1``, ``2``, ``4``, ``8``). ``TP`` is disabled when ``FSDP`` is turned on.
``EP`` / ``EP_SIZE``
Expert parallel for MoE models.
``SEQ_LENGTH``
Input sequence length.
``PR``
Precision for training. ``bf16`` for BF16 (default) or ``fp8`` for FP8 GEMMs.
``AC``
Activation checkpointing (``none``, ``sel``, or ``full``) -- ``sel`` by default.
``NUM_LAYERS``
Use reduced number of layers as a proxy model.
``RECOMPUTE_NUM_LAYERS``
Number of layers used for checkpointing recompute.
