Zpuaa contributed to the vllm-project/vllm-ascend repository by developing hardware-optimized features for Ascend 310P, including custom operators and quantization methods to improve deep learning model performance and reliability. Their work involved refactoring memory management for KV cache systems, integrating Mixture-of-Experts modules, and enhancing attention mechanisms with dedicated mask builders. Using C++, Python, and PyTorch, Zpuaa implemented robust CI/CD pipelines, expanded end-to-end and unit test coverage, and optimized build systems for cross-platform compatibility. The engineering depth is reflected in dynamic tiling, memory optimizations, and seamless integration with PyTorch, enabling scalable, efficient deployment of advanced models on Ascend hardware.

Apr 1, 2026April 2026: Delivered a new AscendC Custom Operator for recurrent gated delta rule calculations in vllm-ascend, including tiling logic and an AscendC kernel. The operator (recurrent_gated_delta_rule_v310) is integrated with the build system, PyTorch bindings, and metadata. Implemented end-to-end validation tests and dynamic tiling/memory management optimizations to support Ascend 310P. No user-facing API changes. This work enables faster recurrent workload execution on Ascend hardware and broadens deployment options for Ascend-enabled models, aligning with performance and reliability goals.
