January 2026 performance summary for ROCm/aiter with a stability-focused bug fix addressing integer overflow in FMHA backward pass to support larger inputs and ensure correctness in deterministic FMHA runs.

October 2025 monthly summary for ROCm/aiter focused on delivering FMHA BWD performance optimizations for GFX950 and stabilizing the test suite. Key changes included updating the composable_kernel submodule to latest revisions and hardening stability by disabling a flaky test to prevent coredumps.

September 2025: ROCm/aiter monthly summary focused on delivering high-impact performance improvements for attention-heavy workloads and enhanced quantized GEMM throughput. Key outcomes include optimized Flash Attention kernels for decode workloads on gfx950 with 16x192 FMHA backward kernels and CK integration, along with deterministic and a32 configurations for 950_1block. Also introduced a8w8 GEMM path with block scaling and bpreshuffle to boost performance on targeted GEMM workloads. Collectively, these efforts increased throughput and reduced latency in decode scenarios, improved reproducibility, and broadened quantization support for performance-critical pipelines.

Month 2025-08: Resolved a critical build issue in ROCm/aiter by updating the 3rdparty/composable_kernel submodule to fix the ELEMENTWISE_BIAS build error, improving build reliability and developer productivity. The change is anchored to commit 50cbc3b92afb35fabfacb716fb48289c243974dc and linked to issue #874 to ensure traceability. This work strengthens core kernel integration and reduces downstream risk for upcoming features.

April 2025 monthly summary for StreamHPC/rocm-libraries: Delivered improvements to FP8 data handling robustness and enabled a basic GEMM example via a new CMake option. This work enhances data accuracy, usability, and developer onboarding for FP8 workflows.
