Developed a real-time inter-process communication system for weight updates and tensor transport in the alibaba/rtp-llm repository, enabling dynamic, low-latency model updates for distributed and reinforcement learning workloads. Leveraged C++, CUDA, and Python to implement JIT-based tensor IPC, batching, and HTTP server support, integrating these features with a weight manager for efficient tensor sharing. Enhanced system reliability by removing DTensor logic to ensure compatibility with AMD hardware and stable shared memory operations across PyTorch tensors. Contributed to backend maintenance by updating Bazel packaging, refining pre-commit tooling, and cleaning up legacy development files, reducing build overhead and improving maintainability.
