Key features include SDPA_OPT kernel performance improvements with FlashAttn2 softmax integration and causal mask optimizations, plus a robustness fix for rotation_trig_lut to support f16 and remove an unused index, with additional tests validating the optimization.

Month: 2024-12 — Summary of key accomplishments for the openvino repository. Implemented Intel SDPA path optimization on the ARL-H platform to accelerate scaled dot product attention on Intel GPUs by forcing the oneDNN path for prefill and the clDNN path for generation, with operation-type based kernel selection to maximize performance. This work was shipped in the openvinotoolkit/openvino repository (commit 571e98d5880a30e9d8ca25f445c343e955e79123, associated with PR #27387). Impact: improved SDPA throughput and reduced latency on ARL-H, enabling faster attention-heavy workloads in production models. Technologies/skills demonstrated include OpenVINO, oneDNN, clDNN, ARL-H platform optimizations, kernel selection strategies, and performance verification under realistic workloads.

2024-11 monthly summary for openvinotoolkit/openvino. Focused on GPU Plugin Fusion Enhancements enabling the GQA pattern, performance improvements for GLM4, and a GLM4V shape inference fix. Implemented a targeted fusion relaxation to UnsqueezeBroadcastReshapeSDPAFusion, reducing overhead on key/value paths and enabling the GQA pattern, significantly improving GLM4 model throughput. The changes were delivered via commit c801f4ec1191c9c4967fe1b8aa1fea67441178fa ([GPU] Relax UnsqueezeBroadcastReshapeSDPAFusion (#27515)).
