Worked on optimizing GPU buffer management in the CodeLinaro/onnxruntime repository, focusing on reducing memory usage for GPU workloads. Refactored the BucketCacheManager by moving buffer release logic from the OnRefresh method to ReleaseBuffer, enabling earlier buffer release and lowering both peak and average GPU memory consumption without impacting throughput. Applied C++ development skills and GPU programming expertise to clarify buffer lifecycle management and improve the maintainability of the cache architecture. Validated the changes across critical code paths to ensure no performance regressions occurred, demonstrating a methodical approach to performance optimization and code quality within a complex, high-performance computing environment.
