January 2026 achievements: Consolidated CUDA 13.0-enabled release pipeline enhancements and wheel publishing for jeejeelee/vllm and red-hat-data-services/vllm-cpu. Implemented PyPI/GitHub release uploads, enabled CUDA 13.0 release image builds, and reorganized CI/CD steps into grouped, maintainable configurations. Fixed wheel upload versioning/exclusion logic to prevent incorrect uploads, improving reliability of PyPI releases. Standardized release workflows across both repos to reduce nightly release friction and improve cross-team collaboration. Result: faster, safer releases with clearer visibility and lower operational risk.

Month 2025-11 --- Monthly work summary for ustclug/Linux201-docs. Focused on delivering comprehensive HPC-related documentation improvements, improving readability and consistency, and reorganizing content for easier access. Key features delivered: 1) Slurm Documentation Enhancements: added installation, configuration, deployment, and scheduler guidance for HPC users. Notable activity included filling in scheduler.md and addressing reviewer and Copilot feedback, with deliberate page reordering to improve flow. 2) HPC/InfiniBand Documentation Expansion and Reorganization: expanded HPC content, added InfiniBand introduction, and moved CUDA-related content into HPC for clearer structure and access. 3) Documentation Standardization and Readability Improvements: standardized terminology across docs, applied language tagging to code fences, and corrected terminology (e.g., 结点 to 节点) for consistency. Major bugs fixed/quality improvements: resolved reviewer comments and Copilot feedback, completed reordering of Slurm-related pages, and applied terminology/code-fence standardizations to reduce ambiguity. Overall impact: improved onboarding and usability for HPC docs, clearer navigation and content structure, and a maintainable foundation for future updates. Technologies/skills demonstrated: technical writing for HPC, documentation strategy and architecture, content reorganization, terminology standardization, code fence language specification, and collaborative review processes.
