Worked on the kvcache-ai/Mooncake repository to deliver deterministic RDMA transport control within the Transfer Engine. The main feature introduced the MC_FORCE_HCA environment variable, allowing operators to explicitly enforce RDMA as the active transport method for large data transfers. This approach provided greater control over transport selection, improving performance predictability and simplifying troubleshooting in data-intensive environments. The work involved C++ development and environment variable management, with attention to system programming practices. Additional updates included enhancements to code readability and maintainability, such as clang-format fixes, ensuring the codebase remains clean and accessible for future development and operational support.
