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.
