September 2025 monthly summary for alibaba/rtp-llm: Delivered a focused codebase cleanup and refactor to improve maintainability and build hygiene. Key work included removing alpha layer normalization kernels and reorganizing headers, which reduces dependency clutter and simplifies future kernel development. Build configurations were streamlined and header/BUILD targets were consolidated to accelerate compilation and onboarding. No major user-facing features or bug fixes completed this month; the emphasis was on structural improvements that lower risk for upcoming feature work and performance optimizations.

May 2025 monthly summary for alibaba/rtp-llm. This month focused on comprehensive documentation updates to improve reproducibility, benchmarking clarity, and onboarding. No code changes deployed; the emphasis was on elevating technical documentation to support faster integration and consistent performance evaluation across teams.

January 2025 (flashinfer-ai/flashinfer) monthly summary: Focused on correctness and performance improvements for NVIDIA Hopper (sm90) by introducing dynamic SM count retrieval for CTA scheduling. The change replaces a hardcoded SM count with a CUDA API query to determine the device's actual SM count, improving scheduling correctness, stability, and GPU utilization for Hopper-based inference workloads. The fix is isolated to GPU scheduling logic and completed with clear traceability for review.
