.. caution::

   This documentation does not reflect the latest version of ROCm vLLM
   inference performance documentation. See :doc:`../vllm` for the latest version.

   The `ROCm vLLM Docker <{{ unified_docker.docker_hub_url }}>`_ image offers
   a prebuilt, optimized environment for validating large language model (LLM)
   inference performance on AMD Instinct™ MI300X series accelerator. This ROCm vLLM
   Docker image integrates vLLM and PyTorch tailored specifically for MI300X series
   accelerators and includes the following components:

   * `ROCm {{ unified_docker.rocm_version }} <https://github.com/ROCm/ROCm>`_

   * `vLLM {{ unified_docker.vllm_version }} <https://docs.vllm.ai/en/latest>`_

   * `PyTorch {{ unified_docker.pytorch_version }} <https://github.com/pytorch/pytorch>`_

   * `hipBLASLt {{ unified_docker.hipblaslt_version }} <https://github.com/ROCm/hipBLASLt>`_

   With this Docker image, you can quickly test the :ref:`expected
   inference performance numbers <vllm-benchmark-performance-measurements-v073>` for
   MI300X series accelerators.

      vLLM is a toolkit and library for LLM inference and serving. AMD implements
      high-performance custom kernels and modules in vLLM to enhance performance.

      more information.

   .. _vllm-benchmark-performance-measurements-v073:

   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>`_
   page provides reference throughput and latency measurements for inferencing
   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 :doc:`latest version of this inference benchmarking environment <../vllm>`.
      The listed measurements should not be interpreted as the peak performance achievable by AMD Instinct MI325X and MI300X accelerators or ROCm software.

   Advanced features and known issues
   ==================================

   For information on experimental features and known issues related to ROCm optimization efforts on vLLM,
   see the developer's guide at `<https://github.com/ROCm/vllm/tree/25070a1841df0dca585b7ddcb967c42aaec4b7c5/docs/dev-docker>`__.

   Getting started
   ===============

   Use the following procedures to reproduce the benchmark results on an
   MI300X accelerator with the prebuilt vLLM Docker image.

   .. _vllm-benchmark-get-started:

   1. Disable NUMA auto-balancing.

      To optimize performance, disable automatic NUMA balancing. Otherwise, the GPU
      might hang until the periodic balancing is finalized. For more information,
      see the :ref:`system validation steps <rocm-for-ai-system-optimization>`.

      .. code-block:: shell

         # disable automatic NUMA balancing
         sh -c 'echo 0 > /proc/sys/kernel/numa_balancing'
         # check if NUMA balancing is disabled (returns 0 if disabled)
         cat /proc/sys/kernel/numa_balancing
         0

   2. Download the `ROCm vLLM Docker image <{{ unified_docker.docker_hub_url }}>`_.

      Use the following command to pull the Docker image from Docker Hub.

      .. code-block:: shell

         docker pull {{ unified_docker.pull_tag }}

   Benchmarking
   ============

   Once the setup is complete, choose between two options to reproduce the
   benchmark results:

   .. _vllm-benchmark-mad-v073:

   {% for model_group in model_groups %}
      {% for model in model_group.models %}

   .. container:: model-doc {{model.mad_tag}}

      .. tab-set::

         .. tab-item:: MAD-integrated benchmarking

            Clone the ROCm Model Automation and Dashboarding (`<https://github.com/ROCm/MAD>`__) repository to a local
            directory and install the required packages on the host machine.

            .. code-block:: shell

               git clone https://github.com/ROCm/MAD
               cd MAD
               pip install -r requirements.txt

            Use this command to run the performance benchmark test on the `{{model.model}} <{{ model.url }}>`_ model
            using one GPU with the :literal:`{{model.precision}}` data type on the host machine.

            .. code-block:: shell

               export MAD_SECRETS_HFTOKEN="your personal Hugging Face token to access gated models"
               python3 tools/run_models.py --tags {{model.mad_tag}} --keep-model-dir --live-output --timeout 28800

            MAD launches a Docker container with the name
            ``container_ci-{{model.mad_tag}}``. The latency and throughput reports of the
            model are collected in the following path: ``~/MAD/reports_{{model.precision}}/``.

            Although the :ref:`available models <vllm-benchmark-available-models-v073>` are preconfigured
            to collect latency and throughput performance data, you can also change the benchmarking
            parameters. See the standalone benchmarking tab for more information.

         .. tab-item:: Standalone benchmarking

            Run the vLLM benchmark tool independently by starting the
            `Docker container <{{ unified_docker.docker_hub_url }}>`_
            as shown in the following snippet.

            .. code-block::

               docker pull {{ unified_docker.pull_tag }}
               docker run -it --device=/dev/kfd --device=/dev/dri --group-add video --shm-size 16G --security-opt seccomp=unconfined --security-opt apparmor=unconfined --cap-add=SYS_PTRACE -v $(pwd):/workspace --env HUGGINGFACE_HUB_CACHE=/workspace --name test {{ unified_docker.pull_tag }}

            In the Docker container, clone the ROCm MAD repository and navigate to the
            benchmark scripts directory at ``~/MAD/scripts/vllm``.

            .. code-block::

               git clone https://github.com/ROCm/MAD
               cd MAD/scripts/vllm

            To start the benchmark, use the following command with the appropriate options.

            .. code-block::

               ./vllm_benchmark_report.sh -s $test_option -m {{model.model_repo}} -g $num_gpu -d {{model.precision}}

            .. list-table::
               :header-rows: 1
               :align: center

               * - Name
                 - Options
                 - Description

               * - ``$test_option``
                 - latency

               * -
                 - throughput
                 - Measure token generation throughput

               * -
                 - all
                 - Measure both throughput and latency

               * - ``$num_gpu``
                 - 1 or 8
                 - Number of GPUs

               * - ``$datatype``
                 - ``float16`` or ``float8``
                 - Data type

            .. note::

               The input sequence length, output sequence length, and tensor parallel (TP) are
               already configured. You don't need to specify them with this script.

            .. note::

               If you encounter the following error, pass your access-authorized Hugging
               Face token to the gated models.

               .. code-block::

                  OSError: You are trying to access a gated repo.

                  # pass your HF_TOKEN
                  export HF_TOKEN=$your_personal_hf_token

            Here are some examples of running the benchmark with various options.

            * Latency benchmark

              Use this command to benchmark the latency of the {{model.model}} model on eight GPUs with the :literal:`{{model.precision}}` data type.

              .. code-block::

                 ./vllm_benchmark_report.sh -s latency -m {{model.model_repo}} -g 8 -d {{model.precision}}

              Find the latency report at ``./reports_{{model.precision}}_vllm_rocm{{unified_docker.rocm_version}}/summary/{{model.model_repo.split('/', 1)[1] if '/' in model.model_repo else model.model_repo}}_latency_report.csv``.

            * Throughput benchmark

              Use this command to throughput the latency of the {{model.model}} model on eight GPUs with the :literal:`{{model.precision}}` data type.

              .. code-block:: shell

                 ./vllm_benchmark_report.sh -s latency -m {{model.model_repo}} -g 8 -d {{model.precision}}

              Find the throughput report at ``./reports_{{model.precision}}_vllm_rocm{{unified_docker.rocm_version}}/summary/{{model.model_repo.split('/', 1)[1] if '/' in model.model_repo else model.model_repo}}_throughput_report.csv``.
