Worked on stabilizing the distributed testing workflow for the kvcache-ai/sglang repository by addressing resource cleanup challenges in multi-server test environments. Using Python and leveraging expertise in distributed systems and testing, implemented a targeted fix that destroys process groups after broadcast operations. This approach resolved persistent port occupation issues, ensuring that resources are properly released and preventing conflicts that previously led to flaky test outcomes. The contribution improved the reliability of continuous integration pipelines by eliminating lingering process groups, resulting in more stable and predictable distributed test runs. The work demonstrated a focused approach to enhancing distributed test infrastructure stability.
