Worked on the vllm-ascend repository to enhance MoE inference performance by developing a W4A8 fused operator that combines dispatch, feed-forward, and combine steps into a single kernel, enabling communication and computation overlap. Leveraged C++ and Python to implement and validate this feature end-to-end, integrating it into the inference pipeline for quantized workloads. Addressed a critical input-parameter bug in the W8A8 dispatch FFN combine fusion operator, stabilizing the quantization workflow. Improved maintainability by translating test comments from Chinese to English, supporting better collaboration. Focused on kernel development, quantization, and performance optimization to deliver measurable latency improvements.
April 2026 performance and reliability snapshot for vllm-ascend. Key deliveries include a W4A8 fused operator for MoE inference that overlaps communication and computation in the dispatch-FFN-combine kernel, with end-to-end validation and integration into the inference pipeline. A critical input-parameter bug in the W8A8 dispatch FFN combine fusion operator was fixed to stabilize the quantization path. Additional maintainability gains were achieved by translating test comments from Chinese to English. Overall, these efforts delivered measurable latency improvements for MoE workloads, reinforced stability of the quantization workflow, and enhanced developer velocity through better test readability.
