Developed asynchronous data transfer capabilities for the kvcache-ai/Mooncake repository, enabling non-blocking read and write operations between local and remote buffers using CUDA streams. The work introduced batch transfer support and leveraged cudaLaunchHostFunc to facilitate stream-based transfers, allowing compute and I/O to overlap efficiently. The transfer engine was refactored and APIs were renamed for clarity, with comprehensive updates to documentation and the addition of targeted unit tests to validate new transfer paths. Logging enhancements and code cleanup were also performed, improving debuggability and reliability. The project utilized C++, CUDA, and Python, with a focus on performance-oriented engineering practices.
