Worked on the PaddlePaddle/Paddle repository, delivering features and stability improvements for XPU compute paths over four months. Developed and integrated the Weight-Only Linear operation, enabling efficient float16 and bfloat16 support with hardware-aware optimization and new XPU kernel registration. Enhanced build reliability by refining CMake configurations and shell scripting for cross-platform stability, addressing libomp/MKL linking and argument handling. Improved kernel robustness by ensuring embedding operations handle empty tensors gracefully, reducing runtime errors in production. Upgraded the XCCL base to support low-latency dispatch and scalable sparse token processing, leveraging C++, CMake, and deep learning optimization to strengthen XPU workload performance.

Sep 1, 2025September 2025 - PaddlePaddle/Paddle: Delivered a critical robustness enhancement to the embedding kernel by ensuring graceful handling of empty input tensors (ids_numel = 0). The kernel now detects empty input and returns early, preventing failures or incorrect behavior for edge-case inputs. This fix reduces runtime errors and improves stability for live deployments that process zero-length sequences. The change references the targeted commit 508b03afb6df39ba04e1887ae035f4d4e8007e48 and aligns with the [xpu] embedding support in_size=0 work (#75201). Overall, the update enhances reliability, reduces risk in production, and demonstrates strong kernel-level quality assurance.
