Phoebe Luo worked on the ROCm/rocm-systems repository, focusing on improving the reliability and clarity of HIP performance testing. She migrated existing HIP performance tests for Compute and Stream to the Catch2 framework, unifying test reporting and enhancing maintainability. By introducing unified logging macros and conditional debug output, Phoebe improved diagnostics and readability for Catch2-based HIP tests. She also developed new kernel latency and dispatch speed tests with advanced timing modes and iterative measurements, providing more accurate performance metrics. Her work leveraged C++, HIP, and benchmarking skills to standardize test reporting, streamline debugging, and accelerate optimization cycles within the HIP stack.
