Heyujiao99

Yujiao He developed RISC-V 64-bit support across two major open-source projects, focusing on platform portability and architecture-specific optimization. For open-mpi/ompi, Yujiao implemented a RISC-V 64-bit timer and integrated it into the timer subsystem, wiring dedicated tests into the CI workflow using C++ and YAML to enable automated validation on RISCV64 via QEMU. In microsoft/DeepSpeed, Yujiao added RISC-V support to the shared memory communication operator, refactoring the codebase for multi-architecture compatibility and maintainability. This work leveraged C++ and Python, addressing the challenges of distributed systems and low-level optimization while improving test coverage and hardware support.
