PROFILE
Jianhao
Worked on performance and stability improvements for GPU-accelerated matrix operations in the intel-xpu-backend-for-triton and ROCm/aiter repositories. Focused on optimizing GEMM kernels by restoring vectorized memory access using an EVEN_MN heuristic and introducing environment variables for async copy control, which enabled targeted performance tuning and resolved runtime errors. Enhanced cross-architecture reliability by expanding distributed testing across CUDA and AMD backends, including float8 support checks. Addressed stability issues by fixing crashes related to uninitialized variables in pointer canonicalization. Utilized C++, Python, and MLIR, applying skills in compiler design, benchmarking, and distributed systems to deliver measurable throughput and reliability gains.

Mar 1, 2026Month: 2026-03 — ROCm/aiter: Delivered performance-focused GEMM improvements and stability fixes with measurable business value. Implemented EVEN_MN heuristic to restore vectorized memory access in GEMM and batched_gemm kernels, preserving compile-time optimizations while regaining vectorization. Introduced an environment variable to control async copy, addressing runtime errors and enabling targeted performance tuning. Fixed issues related to do_not_specialize M/N changes that degraded vectorized stores, enhancing memory throughput. Co-authored by jianlian and azaidy. Commit highlights: 61804c6e70738f2938ab9df733ba2602cebf6d71 and f71a5a2b0e07994d97d0ee179fdaf2ba3c2c9e0e.
