February 2026 Monthly Summary for kvcache-ai/sglang: Code Ownership Realignment for multimodal_gen module and its subdirectories to improve accountability, collaboration, and governance. This work focuses on clarifying ownership rather than introducing new functionality.

November 2025: Delivered NPU Support in CUDA Graph Profiling for the kvcache-ai/sglang repository, enabling profiling of NPU-based computations and improving performance analysis for NPU workloads. Implemented by adapting CUDA graph profiling to recognize and measure NPU execution, providing more accurate bottleneck detection and optimization guidance. The work culminated in commit 5324f37ab33412f108d264d6884e55f93e43b539 (Ascend: adapt enable-profile-cuda-graph for NPU), co-authored by Leo920320 and liupengcheng. Impact: Faster, data-driven optimization cycles for AI workloads on Ascend/NPU accelerators; enhanced visibility into NPU performance, enabling better capacity planning and resource allocation. Overall, a focused feature delivery with cross-team collaboration that aligns profiling tooling with NPU workloads in production-grade metrics.

Concise monthly summary for 2025-09 focused on governance improvements for Ascend hardware code ownership and performance optimizations for Qwen models on Ascend NPUs. Delivered targeted changes to streamline PR routing and improved runtime efficiency on Ascend hardware, enabling faster deployments and better inference performance.

August 2025 monthly summary for the repository ping1jing2/sglang focusing on Ascend NPU profiling enhancements in SGLang. Delivered key feature to enable Ascend NPU profiling within SGLang by patching the PyTorch profiler, with conditional activation and NPU-specific trace handlers when an Ascend device is detected. Ensured profiling data is captured and exported for Ascend hardware to support performance analysis and optimization workflows in production.
