Worked on backend development in the alibaba/MNN repository, focusing on both performance optimization and system reliability using C++. Delivered a fast decode path for LinearAttention when processing single-token sequences, reducing CPU latency by streamlining input tensor handling and bypassing unnecessary computations. This improvement enhanced real-time responsiveness for interactive applications. Additionally, addressed stability in the KV cache subsystem by fixing a crash caused by corrupted prefix cache files and unsafe type narrowing during on-disk cache expansion. Emphasized robust file handling and memory management, resulting in improved uptime and maintainability for caching-heavy inference paths within the codebase.

Apr 1, 2026Month: 2026-04. Focused on CPU-side performance optimization in the MNN repository. Delivered a fast decode path for LinearAttention when sequence length is 1 (L=1), reducing unnecessary computations and streamlining input tensor handling. This improvement lowers latency for single-token inference and enhances real-time responsiveness in interactive applications using LinearAttention.
