PROFILE

Shawn Zhong

Shawn Zhong enhanced the pytorch-labs/tritonbench repository by expanding benchmarking capabilities and profiling fidelity for GPU kernels. He developed a new exponential kernel path, enabling direct performance comparisons between Triton and PyTorch using the vector_exp kernel, and introduced multi-precision benchmarking across FP32, FP16, and BF16. Leveraging C++, Python, and CUDA, Shawn implemented GPU timing instrumentation for both CUDA and AMD platforms, deepening performance analysis. He also profiled the jagged_sum kernel and computed occupancy metrics to guide optimization. Stability and maintainability were improved through fixes for plotting errors, Triton API compatibility, and code linting, supporting robust benchmarking workflows.

June 2025 focused on expanding TritonBench benchmarking capabilities, improving profiling fidelity, and strengthening stability and code quality. Delivered a new exponential kernel path and benchmarking support for TritonBench, enabling direct comparison of Triton exp against PyTorch exp through the vector_exp kernel. Expanded multi-precision benchmarking for vector_exp across FP32/FP16/BF16 with half-precision profiling to revealTorch vs Triton performance across dtypes. Implemented GPU timing instrumentation across CUDA and AMD, adding a dedicated timing kernel and AMD timing for vector_exp to deepen performance analysis. Added jagged_sum profiling and occupancy metrics to quantify kernel efficiency, informing optimization opportunities. Improved reliability and maintainability with plotting stability fixes (eliminating FileNotFoundError), API compatibility adjustments (constexpr instantiation for Triton), and lint fixes to keep the codebase clean. Business value: these changes enable more accurate, hardware-aware performance insights, faster optimization cycles, and reduced downtime in benchmarking dashboards, directly supporting data-driven hardware and kernel tuning decisions for ML workloads.
