Worked on the FlagTree/flagtree repository to deliver a new Rhino RPU backend with kernel execution support, CI integration, and comprehensive documentation in both English and Chinese. Used C++, Bash, and Python to decouple the compiler hint manager from PyTorch, enabling torch-free deployments and broader hardware compatibility. Improved CI reliability by introducing serialized job execution, robust SSH retry logic, and enhanced cleanup routines to manage orphaned processes and prevent resource contention on shared RPU boards. These efforts stabilized hardware validation cycles, reduced downtime from flaky tests, and streamlined onboarding, ultimately accelerating development workflows and improving the reliability of embedded system deployments.

Jun 1, 2026June 2026: Delivered Rhino RPU backend for FlagTree with kernel execution support, CI integration, and build-system wiring, plus comprehensive docs. Implemented torch-free environment support by decoupling the compiler hint manager from PyTorch. Added dedicated RPU CI workflow (RPU3.6) and build-artifact management to improve hardware test reliability. Stabilized the RPU test runner by adding process-group management and a cleanup step to prevent hung launch_kernel processes, ensuring throughput on a shared RPU board. Improved build reliability by cleaning the real build directory to avoid disk exhaustion on the board. Authored English and Chinese RPU installation guides to streamline onboarding. These efforts deliver tangible business value by accelerating hardware validation cycles, reducing downtime, and expanding deployment scenarios.
