Worked on the openvinotoolkit/openvino repository to deliver Xe3p GPU SDPA Configuration Support, focusing on enhancing performance and reliability for Xe3p hardware. Developed new microkernel SDPA configurations in C++ to support head sizes greater than 256, addressing specific error scenarios and improving deployment readiness for large-head inference tasks. The work involved GPU programming and performance optimization, with careful tuning for Xe3p GPU architecture. Collaborated through version control to integrate these changes, ensuring robust SDPA config management. This contribution reduced failure modes in large-head scenarios and demonstrated expertise in C++ development, GPU-specific optimization, and architecture-aware configuration management within the codebase.
