 # vLLM benchmark suite
 ## Introduction
 This directory contains two sets of benchmark for vllm.
 - Performance benchmark: benchmark vllm's performance under various workload, for **developers** to gain clarity on whether their PR improves/degrades vllm's performance
 - Nightly benchmark: compare vllm's performance against alternatives (tgi, trt-llm and lmdeploy), for **the public** to know when to choose vllm.
 See [vLLM performance dashboard](https://perf.vllm.ai) for the latest performance benchmark results and [vLLM GitHub README](https://github.com/vllm-project/vllm/blob/main/README.md) for latest nightly benchmark results.
 ## Performance benchmark quick overview
 **Benchmarking Coverage**: latency, throughput and fix-qps serving on A100 (the support for FP8 benchmark on H100 is coming!), with different models.
 **Benchmarking Duration**: about 1hr.
 **For benchmarking developers**: please try your best to constraint the duration of benchmarking to about 1 hr so that it won't take forever to run.
 ## Nightly benchmark quick overview
 **Benchmarking Coverage**: Fix-qps serving on A100 (the support for FP8 benchmark on H100 is coming!) on Llama-3 8B, 70B and Mixtral 8x7B.
 **Benchmarking engines**: vllm, TGI, trt-llm and lmdeploy.
 **Benchmarking Duration**: about 3.5hrs.
 ## Trigger the benchmark
 Performance benchmark will be triggered when:
 - A PR being merged into vllm.
 - Every commit for those PRs with `perf-benchmarks` label AND `ready` label.
 Nightly benchmark will be triggered when:
 - Every commit for those PRs with `perf-benchmarks` label and `nightly-benchmarks` label.
 ## Performance benchmark details
 See [performance-benchmarks-descriptions.md](performance-benchmarks-descriptions.md) for detailed descriptions, and use `tests/latency-tests.json`, `tests/throughput-tests.json`, `tests/serving-tests.json` to configure the test cases.
 ### Latency test
 Here is an example of one test inside `latency-tests.json`:
 ```json
 [
    {
        "test_name": "latency_llama8B_tp1",
        "parameters": {
            "model": "meta-llama/Meta-Llama-3-8B",
            "tensor_parallel_size": 1,
            "load_format": "dummy",
            "num_iters_warmup": 5,
            "num_iters": 15
        }
    },
 ]
 ```
 In this example:
 - The `test_name` attributes is a unique identifier for the test. In `latency-tests.json`, it must start with `latency_`.
 - The `parameters` attribute control the command line arguments to be used for `benchmark_latency.py`. Note that please use underline `_` instead of the dash `-` when specifying the command line arguments, and `run-performance-benchmarks.sh` will convert the underline to dash when feeding the arguments to `benchmark_latency.py`. For example, the corresponding command line arguments for `benchmark_latency.py` will be `--model meta-llama/Meta-Llama-3-8B --tensor-parallel-size 1 --load-format dummy --num-iters-warmup 5 --num-iters 15`
 Note that the performance numbers are highly sensitive to the value of the parameters. Please make sure the parameters are set correctly.
 WARNING: The benchmarking script will save json results by itself, so please do not configure `--output-json` parameter in the json file.
 ### Throughput test
 The tests are specified in `throughput-tests.json`. The syntax is similar to `latency-tests.json`, except for that the parameters will be fed forward to `benchmark_throughput.py`.
 The number of this test is also stable -- a slight change on the value of this number might vary the performance numbers by a lot.
 ### Serving test
 We test the throughput by using `benchmark_serving.py` with request rate = inf to cover the online serving overhead. The corresponding parameters are in `serving-tests.json`, and here is an example:
 ```json
 [
    {
        "test_name": "serving_llama8B_tp1_sharegpt",
        "qps_list": [1, 4, 16, "inf"],
        "server_parameters": {
            "model": "meta-llama/Meta-Llama-3-8B",
            "tensor_parallel_size": 1,
            "swap_space": 16,
            "disable_log_stats": "",
            "disable_log_requests": "",
            "load_format": "dummy"
        },
        "client_parameters": {
            "model": "meta-llama/Meta-Llama-3-8B",
            "backend": "vllm",
            "dataset_name": "sharegpt",
            "dataset_path": "./ShareGPT_V3_unfiltered_cleaned_split.json",
            "num_prompts": 200
        }
    },
 ]
 ```
 Inside this example:
 - The `test_name` attribute is also a unique identifier for the test. It must start with `serving_`.
 - The `server-parameters` includes the command line arguments for vLLM server.
 - The `client-parameters` includes the command line arguments for `benchmark_serving.py`.
 - The `qps_list` controls the list of qps for test. It will be used to configure the `--request-rate` parameter in `benchmark_serving.py`
 The number of this test is less stable compared to the delay and latency benchmarks (due to randomized sharegpt dataset sampling inside `benchmark_serving.py`), but a large change on this number (e.g. 5% change) still vary the output greatly.
 WARNING: The benchmarking script will save json results by itself, so please do not configure `--save-results` or other results-saving-related parameters in `serving-tests.json`.
 ### Visualizing the results
 The `convert-results-json-to-markdown.py` helps you put the benchmarking results inside a markdown table, by formatting [descriptions.md](tests/descriptions.md) with real benchmarking results.
 You can find the result presented as a table inside the `buildkite/performance-benchmark` job page.
 If you do not see the table, please wait till the benchmark finish running.
 The json version of the table (together with the json version of the benchmark) will be also attached to the markdown file.
 The raw benchmarking results (in the format of json files) are in the `Artifacts` tab of the benchmarking.
 ## Nightly test details
 See [nightly-descriptions.md](nightly-descriptions.md) for the detailed description on test workload, models and docker containers of benchmarking other llm engines.
 ### Workflow
 - The [nightly-pipeline.yaml](nightly-pipeline.yaml) specifies the docker containers for different LLM serving engines.
 - Inside each container, we run [run-nightly-suite.sh](run-nightly-suite.sh), which will probe the serving engine of the current container.
 - The `run-nightly-suite.sh` will redirect the request to `tests/run-[llm serving engine name]-nightly.sh`, which parses the workload described in [nightly-tests.json](tests/nightly-tests.json) and performs the benchmark.
 - At last, we run [scripts/plot-nightly-results.py](scripts/plot-nightly-results.py) to collect and plot the final benchmarking results, and update the results to buildkite.
 ### Nightly tests
 In [nightly-tests.json](tests/nightly-tests.json), we include the command line arguments for benchmarking commands, together with the benchmarking test cases. The format is highly similar to performance benchmark.
 ### Docker containers
 The docker containers for benchmarking are specified in `nightly-pipeline.yaml`.
 WARNING: the docker versions are HARD-CODED and SHOULD BE ALIGNED WITH `nightly-descriptions.md`. The docker versions need to be hard-coded as there are several version-specific bug fixes inside `tests/run-[llm serving engine name]-nightly.sh`.
 WARNING: populating `trt-llm` to latest version is not easy, as it requires updating several protobuf files in [tensorrt-demo](https://github.com/neuralmagic/tensorrt-demo.git).

 ## Description
 This file contains the downloading link for benchmarking results.
 - [benchmarking pipeline](artifact://nightly-pipeline.yaml)
 - [benchmarking results](artifact://results.zip)
 - [benchmarking code](artifact://nightly-benchmarks.zip)
 Please download the visualization scripts in the post
 ## Results reproduction
 - Find the docker we use in `benchmarking pipeline`
 - Deploy the docker, and inside the docker:
  - Download `nightly-benchmarks.zip`.
  - In the same folder, run the following code:
  ```console
  export HF_TOKEN=<your HF token>
  apt update
  apt install -y git
  unzip nightly-benchmarks.zip
  VLLM_SOURCE_CODE_LOC=./ bash .buildkite/nightly-benchmarks/scripts/run-nightly-benchmarks.sh
  ```
 And the results will be inside `./benchmarks/results`.

 # Nightly benchmark
 This benchmark aims to:
 - Provide performance clarity: Provide clarity on which one (vllm, tensorrt-llm, lmdeploy and SGLang) leads in performance in what workload.
 - Be reproducible: one can run the exact same set of benchmarking commands inside the exact same docker by following reproducing instructions.
 Latest results: [results link](https://blog.vllm.ai/2024/09/05/perf-update.html), scroll to the end.
 Latest reproduction guilde: [github issue link](https://github.com/vllm-project/vllm/issues/8176)
 ## Setup
 - Docker images:
  - vLLM: `vllm/vllm-openai:v0.6.2`
  - SGLang: `lmsysorg/sglang:v0.3.2-cu121`
  - LMDeploy: `openmmlab/lmdeploy:v0.6.1-cu12`
  - TensorRT-LLM: `nvcr.io/nvidia/tritonserver:24.07-trtllm-python-py3`
    - *NOTE: we uses r24.07 as the current implementation only works for this version. We are going to bump this up.*
  - Check [nightly-pipeline.yaml](nightly-pipeline.yaml) for the concrete docker images, specs and commands we use for the benchmark.
 - Hardware
  - 8x Nvidia A100 GPUs
 - Workload:
  - Dataset
    - ShareGPT dataset
    - Prefill-heavy dataset (in average 462 input tokens, 16 tokens as output)
    - Decode-heavy dataset (in average 462 input tokens, 256 output tokens)
    - Check [nightly-tests.json](tests/nightly-tests.json) for the concrete configuration of datasets we use.
  - Models: llama-3 8B, llama-3 70B.
    - We do not use llama 3.1 as it is incompatible with trt-llm r24.07. ([issue](https://github.com/NVIDIA/TensorRT-LLM/issues/2105)).
  - Average QPS (query per second): 2, 4, 8, 16, 32 and inf.
    - Queries are randomly sampled, and arrival patterns are determined via Poisson process, but all with fixed random seed.
  - Evaluation metrics: Throughput (higher the better), TTFT (time to the first token, lower the better), ITL (inter-token latency, lower the better).
 ## Known issues
 - TRT-LLM crashes with Llama 3.1 8B [issue](https://github.com/NVIDIA/TensorRT-LLM/issues/2105).
 - TGI does not support `ignore-eos` flag.

 # vLLM benchmark suite
 ## Introduction
 This directory contains a benchmarking suite for **developers** to run locally and gain clarity on whether their PR improves/degrades vllm's performance.
 vLLM also maintains a continuous performance benchmark under [perf.vllm.ai](https://perf.vllm.ai/), hosted under PyTorch CI HUD.
 ## Performance benchmark quick overview
 **Benchmarking Coverage**: latency, throughput and fix-qps serving on B200, A100, H100, Intel® Xeon® Processors, Intel® Gaudi® 3 Accelerators and Arm® Neoverse™ with different models.
 **Benchmarking Duration**: about 1hr.
 **For benchmarking developers**: please try your best to constraint the duration of benchmarking to about 1 hr so that it won't take forever to run.
 ## Trigger the benchmark
 The benchmark needs to be triggered manually:
 ```bash
 bash .buildkite/performance-benchmarks/scripts/run-performance-benchmarks.sh
 ```
 Runtime environment variables:
 - `ON_CPU`: set the value to '1' on Intel® Xeon® and Arm® Neoverse™ Processors. Default value is 0.
 - `SERVING_JSON`: JSON file to use for the serving tests. Default value is empty string (use default file).
 - `LATENCY_JSON`: JSON file to use for the latency tests. Default value is empty string (use default file).
 - `THROUGHPUT_JSON`: JSON file to use for the throughout tests. Default value is empty string (use default file).
 - `REMOTE_HOST`: IP for the remote vLLM service to benchmark. Default value is empty string.
 - `REMOTE_PORT`: Port for the remote vLLM service to benchmark. Default value is empty string.
 ## Performance benchmark details
 See [performance-benchmarks-descriptions.md](performance-benchmarks-descriptions.md) for detailed descriptions, and use `tests/latency-tests.json`, `tests/throughput-tests.json`, `tests/serving-tests.json` to configure the test cases.
 > NOTE: For Intel® Xeon® Processors, use `tests/latency-tests-cpu.json`, `tests/throughput-tests-cpu.json`, `tests/serving-tests-cpu.json` instead.
 > For Intel® Gaudi® 3 Accelerators, use `tests/latency-tests-hpu.json`, `tests/throughput-tests-hpu.json`, `tests/serving-tests-hpu.json` instead.
 > For Arm® Neoverse™, use `tests/latency-tests-arm64-cpu.json`, `tests/throughput-tests-arm64-cpu.json`, `tests/serving-tests-arm64-cpu.json` instead.
 ### Latency test
 Here is an example of one test inside `latency-tests.json`:
 ```json
 [
    {
        "test_name": "latency_llama8B_tp1",
        "parameters": {
            "model": "meta-llama/Meta-Llama-3-8B",
            "tensor_parallel_size": 1,
            "load_format": "dummy",
            "num_iters_warmup": 5,
            "num_iters": 15
        }
    },
 ]
 ```
 In this example:
 - The `test_name` attributes is a unique identifier for the test. In `latency-tests.json`, it must start with `latency_`.
 - The `parameters` attribute control the command line arguments to be used for `vllm bench latency`. Note that please use underline `_` instead of the dash `-` when specifying the command line arguments, and `run-performance-benchmarks.sh` will convert the underline to dash when feeding the arguments to `vllm bench latency`. For example, the corresponding command line arguments for `vllm bench latency` will be `--model meta-llama/Meta-Llama-3-8B --tensor-parallel-size 1 --load-format dummy --num-iters-warmup 5 --num-iters 15`
 Note that the performance numbers are highly sensitive to the value of the parameters. Please make sure the parameters are set correctly.
 WARNING: The benchmarking script will save json results by itself, so please do not configure `--output-json` parameter in the json file.
 ### Throughput test
 The tests are specified in `throughput-tests.json`. The syntax is similar to `latency-tests.json`, except for that the parameters will be fed forward to `vllm bench throughput`.
 The number of this test is also stable -- a slight change on the value of this number might vary the performance numbers by a lot.
 ### Serving test
 We test the throughput by using `vllm bench serve` with request rate = inf to cover the online serving overhead. The corresponding parameters are in `serving-tests.json`, and here is an example:
 ```json
 [
    {
        "test_name": "serving_llama8B_tp1_sharegpt",
        "qps_list": [1, 4, 16, "inf"],
        "server_parameters": {
            "model": "meta-llama/Meta-Llama-3-8B",
            "tensor_parallel_size": 1,
            "swap_space": 16,
            "disable_log_stats": "",
            "load_format": "dummy"
        },
        "client_parameters": {
            "model": "meta-llama/Meta-Llama-3-8B",
            "backend": "vllm",
            "dataset_name": "sharegpt",
            "dataset_path": "./ShareGPT_V3_unfiltered_cleaned_split.json",
            "num_prompts": 200
        }
    },
 ]
 ```
 Inside this example:
 - The `test_name` attribute is also a unique identifier for the test. It must start with `serving_`.
 - The `server-parameters` includes the command line arguments for vLLM server.
 - The `client-parameters` includes the command line arguments for `vllm bench serve`.
 - The `qps_list` controls the list of qps for test. It will be used to configure the `--request-rate` parameter in `vllm bench serve`
 The number of this test is less stable compared to the delay and latency benchmarks (due to randomized sharegpt dataset sampling inside `benchmark_serving.py`), but a large change on this number (e.g. 5% change) still vary the output greatly.
 WARNING: The benchmarking script will save json results by itself, so please do not configure `--save-results` or other results-saving-related parameters in `serving-tests.json`.
 #### Default Parameters Field
 We can specify default parameters in a JSON field with key `defaults`. Parameters defined in the field are applied globally to all serving tests, and can be overridden in test case fields. Here is an example:
 <details>
 <summary> An Example of default parameters field </summary>
 ```json
 {
  "defaults": {
    "qps_list": [
      "inf"
    ],
    "server_environment_variables": {
      "VLLM_ALLOW_LONG_MAX_MODEL_LEN": 1
    },
    "server_parameters": {
      "tensor_parallel_size": 1,
      "dtype": "bfloat16",
      "block_size": 128,
      "disable_log_stats": "",
      "load_format": "dummy"
    },
    "client_parameters": {
      "backend": "vllm",
      "dataset_name": "random",
      "random-input-len": 128,
      "random-output-len": 128,
      "num_prompts": 200,
      "ignore-eos": ""
    }
  },
  "tests": [
    {
      "test_name": "serving_llama3B_tp2_random_128_128",
      "server_parameters": {
        "model": "meta-llama/Llama-3.2-3B-Instruct",
        "tensor_parallel_size": 2,
      },
      "client_parameters": {
        "model": "meta-llama/Llama-3.2-3B-Instruct",
      }
    },
    {
      "test_name": "serving_qwen3_tp4_random_128_128",
      "server_parameters": {
        "model": "Qwen/Qwen3-14B",
        "tensor_parallel_size": 4,
      },
      "client_parameters": {
        "model": "Qwen/Qwen3-14B",
      }
    },
  ]
 }
 ```
 </details>
 ### Visualizing the results
 The `convert-results-json-to-markdown.py` helps you put the benchmarking results inside a markdown table, by formatting [descriptions.md](performance-benchmarks-descriptions.md) with real benchmarking results.
 You can find the result presented as a table inside the `buildkite/performance-benchmark` job page.
 If you do not see the table, please wait till the benchmark finish running.
 The json version of the table (together with the json version of the benchmark) will be also attached to the markdown file.
 The raw benchmarking results (in the format of json files) are in the `Artifacts` tab of the benchmarking.
 #### Performance Results Comparison  
 Follow the instructions in [performance results comparison](https://docs.vllm.ai/en/latest/benchmarking/dashboard/#performance-results-comparison) to analyze performance results and the sizing guide.

 # Cache helper for ROCm base wheels
 #
 # This script manages caching of pre-built ROCm base wheels (torch, triton, etc.)
 # to avoid rebuilding them when Dockerfile.rocm_base hasn't changed.
 #
 # Usage:
 #   cache-rocm-base-wheels.sh check    - Check if cache exists, outputs "hit" or "miss"
 #   cache-rocm-base-wheels.sh upload   - Upload wheels to cache
 #   cache-rocm-base-wheels.sh download - Download wheels from cache
 #   cache-rocm-base-wheels.sh key      - Output the cache key
 #
 # Environment variables:
 #   S3_BUCKET          - S3 bucket name (default: vllm-wheels)
 #   PYTHON_VERSION     - Python version (affects cache key)
 #   PYTORCH_ROCM_ARCH  - GPU architectures (affects cache key)
 #
 # Note: ROCm version is determined by BASE_IMAGE in Dockerfile.rocm_base,
 #       so changes to ROCm version are captured by the Dockerfile hash.

        index_base_dir (Path): Base directory to store index files.

        alias_to_default (str | None): Alias variant name for the default variant, if any.
        comment (str | None): Optional comment to include in the generated HTML files.
    First, parse all wheel files to extract metadata.
    We need to collect all wheel files for each variant, and generate an index for it (in a sub-directory).
    The index for the default variant (if any) is generated in the root index directory.
    If `default_variant` is provided, all wheels must have variant suffixes, and the default variant index
    is purely a copy of the corresponding variant index, with only the links adjusted.
    Otherwise, all wheels without variant suffixes are treated as the default variant.
    If `alias_to_default` is provided, an additional alias sub-directory is created, it has the same content
    as the default variant index, but the links are adjusted accordingly.
