April 2025: PaddleTest — Stabilized test quality for nonzero API validation by fixing test assertions and aligning test data with API behavior. Delivered a precise fix to nonzero API test assertions, updated expected result arrays, and refined assertion logic to ensure accurate comparisons between actual and expected results. This improvement strengthens test reliability, reduces flaky results, and contributes to overall test suite health.

March 2025 monthly summary for PaddlePaddle/Paddle. Delivered two major refactors that simplify API surface and optimize parallel execution: - API simplification: Remove deprecated unshard_dtensor in static mode from the auto_parallel API and clean up related test infrastructure, including removal of test_semi_auto_parallel_llama_model.py, testslist entry, and reverting CMake configurations. - Pipeline Scheduler refactor: Remove outdated IR handling and deprecate non-PIR mode for _create_job_list and _partial_programs, and drop _backward_forward_overlap to streamline PIR-based execution.

Impact: Reduced maintenance burden, cleaner API surface, and more reliable parallel execution groundwork, enabling smoother PIR-based workflows and long-term performance improvements. Technologies/skills demonstrated: Python API refactor, test infrastructure cleanup, CMake configuration adjustments, and pipeline/Scheduler refactoring focused on PIR-based execution.
