Zixuan Zhang contributed backend and performance optimization features to the PaddlePaddle/Paddle and PaddlePaddle/PaddleX repositories over a two-month period. He developed vectorization support for for-loops in the CINN backend, introducing new vectorized data types and transformation passes in C++ and CUDA to leverage hardware vector instructions and improve loop throughput. In PaddleX, he enabled CINN-based static inference optimizations for DCU devices, allowing the compilation path to utilize CINN when both the new IR and CINN are enabled. His work focused on deep learning, compiler optimization, and hardware acceleration, laying a foundation for future performance enhancements across both projects.
