Purpose

Add support for specifying multiple batch sizes via --batch-size in benchmark_moe.py.

Test Plan

  • Modified argparse to accept nargs="+" for batch size.
  • Validated with CLI input: --batch-size 128 256 512.
  • Verified correct tuning and config saving

Also add tuned fused MoE for RedHatAI/Llama-4-Scout-17B-16E-Instruct-FP8-dynamic for B200

Test Result

Confirmed successful tuning for multiple batch sizes in a single run. Config files generated correctly

👋 Hi! Thank you for contributing to the vLLM project.

💬 Join our developer Slack at https://slack.vllm.ai to discuss your PR in #pr-reviews, coordinate on features in #feat- channels, or join special interest groups in #sig- channels.

Just a reminder: PRs would not trigger full CI run by default. Instead, it would only run fastcheck CI which starts running only a small and essential subset of CI tests to quickly catch errors. You can run other CI tests on top of those by going to your fastcheck build on Buildkite UI (linked in the PR checks section) and unblock them. If you do not have permission to unblock, ping simon-mo or khluu to add you in our Buildkite org.

Once the PR is approved and ready to go, your PR reviewer(s) can run CI to test the changes comprehensively before merging.

To run CI, PR reviewers can either: Add ready label to the PR or enable auto-merge.

Summary of Changes

Hello @b8zhong, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the benchmark_moe.py script by allowing users to specify multiple batch sizes for benchmarking in a single run. This is achieved by modifying the argument parser to accept a list of batch sizes and updating the code to iterate over these batch sizes during the benchmarking process. This change improves the flexibility and efficiency of the benchmarking script.

Highlights

  • Argparse Modification: Modified the argparse configuration to accept multiple batch sizes as input via the command line using nargs="+".
  • Batch Size Handling: Updated the code to handle a list of batch sizes instead of a single batch size when the user provides multiple values through the --batch-size argument.

Code Review

This pull request correctly adds support for benchmarking multiple batch sizes in a single run by updating the --batch-size command-line argument to accept multiple values. The implementation is sound. I've added one suggestion to improve the clarity of the new command-line argument to enhance maintainability and prevent potential confusion.
