Worked on the PaddlePaddle/Paddle repository, focusing on deep learning infrastructure and performance optimization. Addressed a backward gradient computation bug in the fused_bias_dropout_residual_layer_norm API, ensuring gradients were correctly calculated when dropout was disabled by conditionally applying the dropout mask. This fix restored stable training behavior and improved numerical stability across training runs, using C++ and CUDA programming. Additionally, refactored profiler instrumentation by removing nvprof_nvtx_pop() calls from compiler.py and gemm.py, reducing profiling overhead and simplifying the user experience. These targeted changes enhanced profiling reliability, supported maintainability, and demonstrated careful validation through integration and regression testing across affected modules.

Jul 1, 2025July 2025 (PaddlePaddle/Paddle): Implemented a critical backward pass fix for fused_bias_dropout_residual_layer_norm when dropout is disabled. The backward gradients now reflect the correct computation by applying the dropout mask only when dropout is active, restoring stable training behavior and reducing gradient-related accuracy diffs observed in tests. The change is integration-tested and recorded under commit 28be65039b839fba7dfdc009776555beaea67e1b, addressing accuracy diff No.90 in related tests.
