Worked on the PaddlePaddle/Paddle repository, focusing on deep learning framework optimization and integration with oneDNN. Over five months, delivered features such as dynamic shape handling for reshape operations, bfloat16 quantization for Concat, and optimization level tuning to balance performance and stability. Used C++ and Python to refactor placement logic, enhance pattern matching, and implement new inference passes for quantized computation. Addressed compatibility by upgrading oneDNN versions and adjusting unit tests, while resolving a critical bug in bfloat16 input handling. The work emphasized compiler development, inference optimization, and robust software engineering practices to improve model throughput and reliability.

Mar 1, 2025March 2025: PaddlePaddle/Paddle OneDNN integration stabilization and compatibility improvements. Stabilized the OneDNN execution path by ensuring OneDNNOperatorDialect is registered in IrContext and upgrading OneDNN to v3.6, with corresponding unit test adjustments to maintain compatibility. These changes reduce runtime errors when enabling OneDNN and improve CPU performance portability across platforms.

Dec 1, 2024December 2024 monthly summary for PaddlePaddle/Paddle. Key feature delivered: OneDNN integration upgrades with bf16 quantization support for the Concat operation. Implemented a new inference pass that inserts quantize and dequantize around Concat to compute in bf16 with oneDNN, transforming inputs to bf16 for computation and converting back to the original dtype. This delivers faster inference and improved throughput for Concat-heavy models. Commits: d0f9dbb5440f95d8e7073fa58bb6924783ea0b51 (Upgrade oneDNN to v3.5), 1e9f2b363ce20c946b9790d388af72c701ee7b62 ([PIR][oneDNN] Add quantization pattern for Concatence).
