Worked on the vllm-project/vllm-ascend repository to deliver Gemma4 Graph Execution A5 support and enhance inference reliability across Ascend hardware. Focused on deep learning and backend development using Python and PyTorch, implementing per-layer metadata binding, workspace state management, and MoE compatibility for Gemma4 models. Refactored attention graph logic for maintainability and introduced unit tests to ensure code quality. Addressed deployment stability by adding CPU fallback for Mamba align postprocess on 310P devices and expanded large-head attention support for A2/A3 hardware, enabling efficient inference and broader device compatibility while maintaining robust test coverage and preserving existing behaviors.

Jun 1, 2026June 2026 monthly summary focusing on delivering Gemma4 Graph Execution A5 Support in vllm-ascend, maintaining compatibility with existing configurations, and improving test coverage and code quality. Key outcomes include per-layer FIA metadata binding during graph replay, reuse of graph workspaces via the update path with a Gemma4-specific max-workspace cache, and Gemma4 MoE compatibility for config/routing/activation differences. Additionally, attention graph helper logic was refactored into a dedicated module to isolate execution path concerns. All changes were validated with unit tests and local quality checks, preserving non-Gemma4 behavior.
