LEO reimplements the OpenCL API atop Intel's Level Zero interface, aiming to consolidate two separate driver stacks into one. Still disabled by default, LEO requires setting the 'EnableLEO' environment variable and shows 'OpenCL 3.0 LEO' in version info when active. Core functionality works but not all OpenCL extensions are implemented yet. The release also brings performance improvements including a reduced USM pool size to 2MB, new AVX2 and AVX-512 optimized memory copy functions, USM pool manager enablement on device USM in OpenCL, and new features like zeGraphGetIdExt and Sysman Fan API support on Linux. ## Full article daily.dev links to this article rather than hosting it.
