Worked on the StreamHPC/rocm-libraries repository, focusing on performance optimization and numerical correctness in high-performance computing contexts. Developed a YAML-driven workflow for tuning HipBLASLt kernel parameters, enabling size-aware optimization across diverse ROCm hardware and improving reproducibility in performance measurement. Addressed numerical instability in the TensileLite CPU path by refining BFloat16 handling in SaturateCast, ensuring accurate NaN propagation and stable results between CPU and GPU reference paths. Utilized C++ and YAML to implement these solutions, demonstrating expertise in GPU computing, low-level optimization, and numerical computing. The work enhanced both performance and reliability for downstream users and continuous integration pipelines.

Apr 1, 2025April 2025 monthly summary for StreamHPC/rocm-libraries focused on the TensileLite CPU path. Key features delivered: - Bug fix: TensileLite CPU NaN handling for BFloat16 in SaturateCast, updating the cast flow to convert BFloat16 accumulators to float before the final cast to the target type T. This improves numerical correctness in reference/CPU paths. Commits implemented: 2409904e1e0a0dd56b984d8607cae25367ec7eb4; b1f92aa25a37ab8c83c2f81e2922898081664e9c. Major bugs fixed: - NaN propagation and numerical instability in TensileLite CPU path due to SaturateCast handling; resolved by explicit cast sequence, ensuring stable and predictable results across CPU reference tests. Overall impact and accomplishments: - Restored numerical correctness and stability for BFloat16 computations on the CPU reference path, reducing test flakiness and aligning CPU results with GPU paths. This improves reliability for CI validation, documentation, and downstream consumers relying on CPU references. Technologies/skills demonstrated: - C++ numeric type handling, BFloat16 casting, and safe type conversions; debugging and patch maintenance in a performance-sensitive code path; commit-driven development and validation across CPU reference implementations.
