PROFILE

Daohang Shi

Over five months, contributed to matrix multiplication optimization and benchmarking across the facebookexperimental/triton, pytorch-labs/tritonbench, and pytorch/pytorch repositories. Developed and refined GPU-accelerated kernels, introduced autotuning and configuration heuristics, and enhanced validation through regression testing and CI improvements. Leveraged Python and CUDA to implement dynamic template filtering, memory management, and precision support for TLX matmul operations. Improved performance benchmarking by adding visualization tools and fallback mechanisms for operator reliability. Focused on maintainable backend development, streamlined configuration management, and robust unit testing, resulting in scalable, high-performance deep learning workflows and more reliable matrix operations for both research and production environments.
