Worked on the ROCm/clr repository to enhance GPU hardware support, stability, and performance through targeted feature development and bug fixes. Over four months, contributed C++ and C code to expand architecture compatibility, including adding support for gfx950 and gfx9-4-generic targets, and improved device driver reliability by refining resource allocation logic. Addressed atomic operation correctness for float and double types by refactoring low-level CUDA/HIP routines, ensuring robust and portable device behavior. Focused on debugging and performance optimization, the work included resolving compilation warnings, improving logging accuracy, and updating documentation, resulting in broader hardware coverage and more maintainable code across ROCm platforms.
