:description: How to train a model using Megatron-LM for ROCm.
:keywords: ROCm, AI, LLM, train, Megatron-LM, megatron, Llama, tutorial, docker, torch
********************************************
Training a model with Primus and Megatron-LM
********************************************
`Primus <https://github.com/AMD-AGI/Primus>`__ is a unified and flexible
training framework for AMD Instinct GPUs designed to support multiple training
engine backends -- including Megatron -- to deliver scalable, high-performance
model training. Performance acceleration is powered by `Primus Turbo
<https://github.com/AMD-AGI/Primus-Turbo>`__ and ROCm libraries.
.. note::
For a unified training solution on AMD GPUs with ROCm, the `rocm/megatron-lm
<https://hub.docker.com/r/rocm/megatron-lm/>`__ Docker Hub registry will be
deprecated soon in favor of `rocm/primus <https://hub.docker.com/r/rocm/primus>`__.
The ``rocm/primus`` Docker containers will cover PyTorch training ecosystem frameworks,
including Megatron-LM and :doc:`torchtitan <primus-pytorch>`.
Primus with Megatron is designed to replace the :doc:`ROCm Megatron-LM
training <megatron-lm>` workflow. To learn how to migrate workloads from
Megatron-LM to Primus with Megatron, see
:doc:`previous-versions/megatron-lm-primus-migration-guide`.
AMD provides a ready-to-use Docker images for MI355X, MI350X,
MI325X, and MI300X GPUs containing essential components for Primus, ROCm, and
Megatron-LM.

might vary by model -- select one to get started.

.. note::
Some models, such as Llama, require an external license agreement through
a third party (for example, Meta).
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-primus-megatron-lm-training-v259:
Environment setup
=================
.. datatemplate:yaml:: /data/how-to/rocm-for-ai/training/primus-megatron-benchmark-models.yaml
Use the following instructions to set up the environment, configure the script to train models, and
reproduce the benchmark results on AMD Instinct GPUs.
.. _amd-primus-megatron-lm-requirements-v259:
Pull the Docker image
.. datatemplate:yaml:: /data/how-to/rocm-for-ai/training/primus-megatron-benchmark-models.yaml
{% set dockers = data.dockers %}
1. Pull the appropriate Docker image for your AMD GPU architecture from Docker Hub.
.. tab-set::
{% for supported_gpus, docker in dockers.items() %}
.. tab-item:: {{ supported_gpus }}
:sync: {{ supported_gpus }}
.. code-block:: shell
docker pull {{ docker.pull_tag }}
{% endfor %}
2. Launch the Docker container.
.. tab-set::
{% for supported_gpus, docker in dockers.items() %}
.. tab-item:: {{ supported_gpus }}
:sync: {{ supported_gpus }}
.. code-block:: shell
docker run -it \
--device /dev/dri \
--device /dev/kfd \
--device /dev/infiniband \
--network host --ipc host \
--group-add video \
--cap-add SYS_PTRACE \
--security-opt seccomp=unconfined \
--privileged \
-v $HOME:$HOME \
--shm-size 128G \
--name primus_training_env \
{{ docker.pull_tag }}
{% endfor %}
3. Use these commands if you exit the ``primus_training_env`` container and need to return to it.
.. code-block:: shell
docker start primus_training_env
docker exec -it primus_training_env bash
The Docker container hosts verified commit ``e16b27b`` of the `Primus
<https://github.com/AMD-AGI/Primus/tree/e16b27b>`__ repository.
.. _amd-primus-megatron-lm-environment-setup-v259:
Configuration
=============
Primus defines a training configuration in YAML for each model in
`examples/megatron/configs <https://github.com/AMD-AGI/Primus/tree/e16b27bf6c1b2798f38848fc574fee60d9a9b902/examples/megatron/configs>`__.
.. datatemplate:yaml:: /data/how-to/rocm-for-ai/training/primus-megatron-benchmark-models.yaml
{% set model_groups = data.model_groups %}
{% for model_group in model_groups %}
{% for model in model_group.models %}
.. container:: model-doc {{ model.mad_tag }}
For example, to update training parameters for {{ model.model }}, you can
update ``examples/megatron/configs/{{ model.config_name }}``. Training
configuration YAML files for other models follow this naming convention.
{% endfor %}
{% endfor %}
.. note::
See :ref:`Key options <amd-primus-megatron-lm-benchmark-test-vars>` for more information on configuration options.
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`` field to toggle between mock and real data. The default
value is ``true`` for enabled.
.. code-block:: yaml
mock_data: true
* If you're using a real dataset, update the ``train_data_path`` field to point to the location of your dataset.
.. code-block:: bash
mock_data: false
train_data_path: /path/to/your/dataset
Ensure that the files are accessible inside the Docker container.
.. _amd-primus-megatron-lm-tokenizer-v259:
Tokenizer
---------
Set the ``HF_TOKEN`` environment variable with
right permissions to access the tokenizer for each model.
.. code-block:: bash
# Export your HF_TOKEN in the workspace
export HF_TOKEN=<your_hftoken>
.. note::
In Primus, each model uses a tokenizer from Hugging Face. For example, Llama
3.1 8B model uses ``tokenizer_model: meta-llama/Llama-3.1-8B`` and
``tokenizer_type: Llama3Tokenizer`` defined in the `llama3.1-8B model
<https://github.com/AMD-AGI/Primus/blob/e16b27bf6c1b2798f38848fc574fee60d9a9b902/examples/megatron/configs/llama3.1_8B-pretrain.yaml>`__
definition.
.. _amd-primus-megatron-lm-run-training-v259:
Run training
============
Use the following example commands to set up the environment, configure
:ref:`key options <amd-primus-megatron-lm-benchmark-test-vars>`, and run training on
AMD Instinct GPUs using Primus with the Megatron backend.

Multi-node training examples
----------------------------
Refer to :doc:`/how-to/rocm-for-ai/system-setup/multi-node-setup` to configure your environment for multi-node
training.
To run training on multiple nodes, you can use the

.. note::
* Make sure correct network drivers are installed on the nodes. If inside a Docker, either install the drivers inside the Docker container or pass the network drivers from the host while creating Docker container.
* If ``NCCL_IB_HCA`` and ``NCCL_SOCKET_IFNAME`` are not set, Primus will try to auto-detect. However, since NICs can vary accross different cluster, it is encouraged to explicitly export your NCCL parameters for the cluster.
* To find your network interface, you can use ``ip a``.
* To find RDMA interfaces, you can use ``ibv_devices`` to get the list of all the RDMA/IB devices.
* Remember to set ``DOCKER_IMAGE`` and ``HF_TOKEN`` (see :ref:`amd-primus-megatron-lm-tokenizer-v259`) as appropriate.

set ``use_distributed_optimizer`` and ``overlap_param_gather`` to ``false``.
profile
To enable PyTorch profiling, set these parameters:
.. code-block:: yaml
profile: true
use_pytorch_profiler: true
profile_step_end: 7
profile_step_start: 6
train_iters
The total number of iterations (default: 50).
mock_data
True by default.
micro_batch_size
Micro batch size.
global_batch_size
Global batch size.
recompute_granularity
For activation checkpointing.
num_layers
For using a reduced number of layers as with proxy models.
Known issues
============
PyTorch Profiler may produce inaccurate traces when CPU activity profiling is enabled.

Previous versions
=================
See :doc:`previous-versions/megatron-lm-history` to find documentation for previous releases
of the ``ROCm/megatron-lm`` Docker image.
This training environment now uses Primus with Megatron as the primary
configuration. Limited support for the legacy ROCm Megatron-LM is still
available; see the :doc:`megatron-lm` documentation.
