PROFILE
Jingzong Liu
Worked on the PaddlePaddle/Paddle repository to enhance the reliability of GPU-accelerated training by addressing two critical bugs. Focused on correcting a CUDA kernel for the correlation gradient path, which involved renaming the kernel for clarity and improving code formatting to support maintainability and correctness. Additionally, stabilized unit tests for distributed APIs in dygraph mode by tuning environment variables and import paths, and disabling a problematic API to resolve test failures. Leveraged expertise in C++, Python, and CUDA to improve CI stability and reduce production risk, ultimately supporting safer deployment of distributed training features and strengthening code quality.
