Worked on enhancing the DeepEP codebase by implementing peer-to-peer NVLink inter-node communication, enabling direct GPU-to-GPU memory access when supported. This involved refactoring the internode_ll.cu kernel to leverage NVLink P2P paths, with a safe fallback to NVSHMEM for environments where P2P is unavailable. Buffer management in buffer.py was updated to conditionally disable P2P based on environment variables, ensuring robust operation across varied deployment scenarios. The work focused on distributed systems and low-latency communication, utilizing CUDA and Python to optimize performance. All changes were contributed to the deepseek-ai/DeepEP repository, addressing deployment flexibility and communication efficiency.
