PROFILE
Qiuyang Yue
Over two months, contributed to jeejeelee/vllm and DarkLight1337/vllm by delivering targeted reliability and performance improvements for large-model inference. Addressed a TOCTOU race in the SimpleCPUOffloadScheduler, ensuring blocks were pinned before use to prevent crashes during KV connector scheduling. Focused on optimizing Mixture-of-Experts (MoE) kernels, achieving a 25% throughput gain for Qwen3-Next-80B on H100 GPUs by refining CUDA kernel configurations. Introduced an abstract base class to standardize MoE backend selection and refactored unquantized MoE logic for maintainability. Work emphasized Python, CUDA, and PyTorch, with careful benchmarking and alignment to evolving core library standards.

May 1, 2026Month: 2026-05. Focused on stabilizing KV connector scheduling and improving reliability. Delivered a critical TOCTOU fix in SimpleCPUOffloadScheduler to ensure blocks identified as hits are pinned and not evicted before use, preventing crashes and improving reliability in the KV connector scheduling. The changes reduce runtime errors under load and contribute to more predictable KV operations.
