This PR adds a bench serving test with max-concurrency=256 and should add balancedness metrics in the next PRs.

Summary of Changes

Hello @hnyls2002, 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 distributed attention load balance benchmark by integrating a new serving test. The primary goal is to evaluate performance under high concurrency, specifically with max-concurrency=256, laying the groundwork for future balancedness metric additions. The changes involve updating benchmark argument utilities and adding a dedicated test case to exercise this new capability.

Highlights

  • Benchmark Argument Enhancement: The get_benchmark_args utility function was updated to accept a new max_concurrency parameter, allowing for more flexible benchmark configurations.
  • New Serving Benchmark Test: A new test method, test_bench_serving, has been introduced within TestDisaggregationDPAttentionRoundRobin to run a serving benchmark with max_concurrency set to 256.
  • Benchmark Utility Imports: Necessary functions, run_benchmark and get_benchmark_args, were imported to support the new serving test.

🧠 New Feature in Public Preview: You can now enable Memory to help Gemini Code Assist learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. Click here to enable Memory in your admin console.

Changelog
  • python/sglang/test/test_utils.py
    • Added max_concurrency parameter to the get_benchmark_args function definition and its internal SimpleNamespace.
  • test/registered/distributed/test_disaggregation_dp_attention.py
    • Imported run_benchmark from sglang.bench_serving.
    • Imported get_benchmark_args from sglang.test.test_utils.
    • Added a new test method test_bench_serving to TestDisaggregationDPAttentionRoundRobin class, which executes a serving benchmark with max_concurrency=256.

Code Review

This pull request enhances the DP attention benchmark by adding a new serving test with max_concurrency=256. The changes are logical and well-implemented. My only suggestion is to strengthen an assertion in the new test to ensure all benchmark requests complete successfully, which will make the test more robust at catching potential regressions. Additionally, there is a minor typo in the PR title ('blance' should be 'balance').
