Sun, Chenwei
Worked on the HazyResearch/ThunderKittens repository to deliver targeted improvements in CUDA kernel correctness and performance. Addressed Clang frontend parsing issues by refining constexpr calculations and static_assert conditions in CUDA headers, ensuring accurate memory operation parameters and reducing defect risk. Enhanced warp-level reduction efficiency by replacing a runtime conditional with a compile-time if constexpr, minimizing unnecessary branching for large element reductions. Leveraged expertise in C++, CUDA, and metaprogramming to improve kernel reliability and throughput. The work focused on both compiler error resolution and performance optimization, contributing to maintainable, high-performance GPU programming within the ThunderKittens codebase over the project period.
