Worked on the ROCm/aiter repository to deliver advanced GPU acceleration features for deep learning and machine learning workloads, focusing on performance optimization and hardware compatibility. Developed and optimized CUDA and C++ kernels to support new data types such as BFloat16 and FP8, enabling efficient mixed-precision computations on AMD GPUs. Enhanced the attention mechanism by refactoring kernel layouts and enabling direct 5D tensor access, which improved throughput and code maintainability. Expanded test automation and coverage using Python and Triton, ensuring robust validation across hardware versions. Prioritized code quality, cross-version stability, and streamlined contributor onboarding through improved tooling and documentation practices.

Jul 1, 2025In 2025-07, ROCm/aiter delivered MI350 accelerator support and reinforced test reliability. We introduced a dedicated preprocessor macro to enable the MI350 backend for the skinny_gemm path with smaller matrices, updated the test suite to exercise this path on MI350 hardware, and fixed test_skinny_gemm in a8w8_pertoken_quant mode. These changes broaden hardware compatibility, reduce risk of regressions, and position ROCm/aiter to support next-generation AMD accelerators.
