Notices and disclaimers
As announced previously, Windows driver support of integrated graphics processors included with 6th - 10th Gen Intel® Core™ Processor and related Intel® Atom®, Pentium®, and Celeron® processors is deprecated and has moved to maintenance mode. Only security and critical bug fixes will be updated.
Directory Layout
Directory layout is improved across all products to streamline installation and setup.
The Unified Directory Layout is implemented in 2024.0. If you have multiple toolkit versions installed, the Unified layout ensures that your development environment contains the correct component versions for each installed version of the toolkit.
The directory layout used before 2024.0, the Component Directory Layout, is still supported on new and existing installations.
For detailed information about the Unified layout, including how to initialize the environment and advantages with the Unified layout, refer to Use the setvars and oneapi-vars Scripts with Linux and Use the setvars and oneapi-vars Scripts with Windows.
Known Issues
- Intel® oneAPI Toolkits 2022.1.3 and earlier and Intel® Parallel Studio XE (any version) do not support Microsoft Visual Studio 2022. On systems with Microsoft Visual Studio 2022 installed, Intel® oneAPI and Intel® Parallel Studio XE installers may fail during installation, upgrade, modification, or uninstallation. Refer to this article for more information.
oneAPI tools using existing integrated graphics processor functionality in the aforementioned processors may continue to work, but will no longer be supported. Note that CPU functionality for these processors remains fully supported and unaffected.
Intel technologies may require enabled hardware, software or service activation.
No product or component can be absolutely secure.
Your costs and results may vary.
