PROFILE
Hang Yang
Hang Yu worked on the alibaba/rtp-llm repository, focusing on stabilizing the build system and improving distributed training reliability. Over two months, he resolved a library conflict by removing unused linker options and dependencies, which streamlined the build process and reduced maintenance overhead. Using C++ and Python, he also addressed issues in distributed training by disabling a custom allreduce operation in tp4, preventing incorrect outputs and enhancing correctness. Additionally, he expanded the performance testing suite with new Qwen72B model inputs, strengthening validation coverage. His work demonstrated depth in build systems, dependency management, and performance testing for large-scale machine learning infrastructure.

Feb 1, 2025February 2025 - alibaba/rtp-llm: Stabilized distributed training in tp4 by disabling the custom allreduce to prevent incorrect outputs, and expanded performance validation by adding Qwen72B test input configurations. These changes reduce risk of silent incorrect results in production deployments and strengthen performance regression coverage. Key achievements: 1) Disabled custom allreduce in tp4 (commit 92e180b70db60ae9d034159cebf16db23a752ed1). 2) Added Qwen72B test inputs to performance suite. Impact: improved correctness and reliability in distributed training, faster issue detection, better validation coverage. Technologies: distributed training, performance testing, test suite augmentation.
