July 2026: Delivered a CK upgrade and substantial MHA sink enhancements in ROCm/aiter, improving performance, compatibility, and reliability for attention workloads. Upgraded Composable Kernel (CK) to a newer version and aligned kernel launch and block size configurations with updated type requirements. Enhanced Multi-Head Attention (MHA) sink logic to support both streaming-sink windows and learned per-head sink pointers, with updated sink token detection. Implemented targeted build/test fixes and BlockSize type alignment to stabilize CI and CI-driven validation. These changes were supported by submodule pinning and patch overlays, delivering tangible business value through faster iteration, broader hardware compatibility, and more robust throughput for attention models.

May 2026 monthly summary for ROCm/composable_kernel focusing on stabilizing and validating mixed-precision GEMM paths. Delivered a targeted bug fix for grouped GEMM mixed-precision correctness, improved data type handling for FP8/BF8, and added hardware configuration support to prevent compilation errors and incorrect results. Enhanced cross-GPU compatibility (GFX950/GFX1250) and ensured alignment with ROCm- libraries PR #7537.

June 2025 monthly summary for StreamHPC/rocm-libraries highlighting the delivery of a new FP8 GEMM client example and associated build integration, with performance reporting capabilities.
