2026-07 monthly summary: Delivered a critical reliability fix for the fused MoE kernel in ROCm/aiter by enforcing KBatch >= 2 for split-k, preventing uninitialized memory and ensuring output accuracy in block FP8 paths. Added tests validating the fix against reference implementations. Hardened the CK stage1 path to respect the KBatch constraint across tuned configurations. Result: improved stability, correctness, and predictability of MoE inference, especially for small batch sizes and FP8 quantization, reducing risk of gibberish outputs in production.

June 2026 monthly summary for DarkLight1337/vllm and ROCm/aiter. The month focused on delivering robust fixes, performance optimizations, and expanded validation across two critical repositories, with a strong emphasis on business value, reliability, and GPU-accelerated inference performance.

April 2026: Delivered scalable Multi-Head Attention (MLA) support with FP8 key-value caching for tensor parallelism on Kimi K2.5, enabling efficient MLA across head configurations with nhead < 16 and TP=8. This feature improves training throughput and memory efficiency on AMD hardware. Co-authored PR #21213 with RoyWang (commit dd49127fe612800d2f2aa258c9b7086043f103fa). No blockers encountered; prepared for broader production adoption.

March 2026 (ROCm/aiter): Implemented a logging duplication prevention fix to improve observability and debugging reliability. By setting the logger's propagate attribute to False, duplicate log outputs from multiple handlers were eliminated, reducing log noise and speeding incident investigations. No new user-facing features were released this month; however, the observability improvement delivers clear business value by enhancing troubleshooting efficiency and system reliability.

February 2026 (2026-02) focused on performance optimization for the Kimi K2.5 fused_moe_triton path and expanding int4_w4a16 support in yhyang201/sglang. Implemented tuning, block shape and architecture configuration adjustments, and added quantization support to improve inference throughput and latency on supported hardware. No major bugs fixed this period; work establishes a solid foundation for production validation and future optimizations, with clear traceability to commits.

Monthly summary for 2026-01 focusing on key accomplishments, with emphasis on business value and technical reliability. The primary work this month was ensuring consistency and compatibility in AMD-specific diffusion dependencies within the kvcache-ai/sglang repository, aligning the AMD diffusion configuration with the main project configuration to reduce drift and potential performance variation for AMD users.

December 2025 performance summary for hao-ai-lab/FastVideo: Delivered GPU-accelerated sliding tile attention and broadened hardware support, enhancing throughput and deployment flexibility. Key deliverables include a Triton-accelerated sliding_tile attention with ROCm support, ROCm backend build improvements, AMD RDNA compatibility fixes for the STA Triton kernel, and a targeted fix for sliding_tile_attn with sdpa. These efforts improve performance on NVIDIA and AMD GPUs, simplify cross-vendor deployments, and strengthen kernel stability.
