Susanta Bhattacharjee
Contributed to the openvinotoolkit/openvino repository by developing two core features focused on GPU performance and model efficiency. Delivered external weight sources caching for the Intel GPU plugin, enabling support for weights not loaded from binary files and reducing model initialization time through enhanced caching strategies. Additionally, implemented a performance enhancement for the PhiSlica model by caching tensor layout and offset calculations, which optimized padded-tensor copying and reduced wait times between queries by approximately 200x. These solutions were engineered using C++ and GPU programming, with an emphasis on model caching, plugin development, and performance optimization across dynamic inference workflows.

Aug 1, 2025Month: 2025-08 – Reached a focused contribution to the OpenVINO project by delivering external weight sources caching for the Intel GPU plugin. Key feature enables weightless cache attributes to support weights not loaded from binary files (e.g., inputs from ONNX Runtime), with updates to the program loading path to leverage caching for improved performance. Major bugs fixed: none reported this month. Overall impact: reduced model initialization time and improved inference throughput on Intel GPUs, better integration with dynamic weight sources in production pipelines, and a stronger caching strategy in the OpenVINO plugin architecture. Technologies/skills demonstrated: C++, caching strategies, loader pipeline enhancements, performance optimization, and cross-component collaboration with the Intel GPU plugin and ONNX Runtime workflows.
