June 2026 performance month focused on delivering a high-impact, multi-path gfx942 Opus GEMM backend with bf16 support, plus a strategic codegen refactor and robust validation across architectures. Key outcomes include a16w16 bf16 GEMM full pipeline family with per-arch dispatch and runtime arch routing, new split-K and WKC paths, and bf16 tuning updates for DSV4 workloads. Implemented a safe fallback for split-K reductions to preserve correctness and performance. Refactored codegen to move per-arch logic into dedicated arch modules, reducing overall complexity and improving maintainability. Achieved end-to-end multi-arch validation (gfx942/gfx950), successful op_tests, and parity sweep coverage. Updated per-model bf16 tuning configurations for gfx942, enabling faster deployment and more reliable performance across models. Business value: higher performance, broader hardware support (gfx942/gfx950), improved reliability and faster CI-driven deployments. Technologies/skills demonstrated: CUDA/HIP kernel development, GEMM/MFMA optimization, split-K and WKC path engineering, BF16 tuning, per-arch codegen, runtime arch routing, cross-arch validation, and build/config management.
