Over a two-month period, contributed to open-mpi/ompi and microsoft/DeepSpeed by building RISC-V 64-bit support for both timer functionality and shared memory communication. For Open MPI, implemented a RISC-V 64-bit timer and integrated it into the CI workflow using QEMU-based testing, enhancing portability and automated validation for RISCV64 systems. In DeepSpeed, added architecture-specific support for the SHM communication operator, refactoring code to accommodate multiple CPU architectures and improve maintainability. The work relied on C++, Python, and system programming skills, with a focus on low-level optimization, CI/CD integration, and expanding hardware compatibility for distributed and embedded systems.
