May 2026 monthly summary for repository yhyang201/sglang focused on stabilizing rotary embeddings handling on gfx950 backends and improving cross-backend compatibility.

In March 2026, delivered a focused performance optimization for the MoEGate path in ping1jing2/sglang. Implemented a conditional kernel switch to the aiter_dsv3_router_gemm kernel when the number of experts is 256 or fewer, delivering improved throughput and lower latency for small-expert configurations. No major bugs fixed this month; all work centered on performance and maintainability. This work enhances business value by accelerating MoE inference in typical deployment patterns, reducing resource usage, and laying groundwork for broader AMD-optimized kernel support.
