During May 2025, Ying Cao developed peer-to-peer NVLink inter-node communication for the DeepEP repository, focusing on enabling direct GPU-to-GPU memory access to improve low-latency distributed systems. Ying refactored the internode_ll.cu kernel in C++ and CUDA to leverage NVLink P2P paths, while implementing a safe fallback to NVSHMEM when P2P was unavailable. The work also included updating Python-based buffer management to conditionally disable P2P via environment variables, ensuring deployment flexibility. This feature addressed the need for efficient, adaptable inter-node communication, demonstrating depth in performance optimization and distributed systems engineering within a complex, production-grade codebase.
