Key Features
The compiler supports these key features:
- Intel® oneAPI Level Zero: The Intel® oneAPI Level Zero (Level Zero) Application Programming Interface (API) provides direct-to-metal interfaces to offload accelerator devices.
- OpenMP* Support: Compiler support for OpenMP 5.0 Version TR4 features and some OpenMP Version 5.1 features.
- Pragmas: Information about directives to provide the compiler with instructions for specific tasks, including splitting large loops into smaller ones, enabling or disabling optimization for code, or offloading computation to the target.
- Offload Support: Information about SYCL*, OpenMP, and parallel processing options you can use to affect optimization, code generation, and more.
- Latest Standards: Use the latest standards including C++ 20, SYCL, and OpenMP 5.0 and 5.1 for GPU offload.

Clang Option Support
Clang compiler options are supported for this compiler. We do not document these options, but you can check
-help on the command line to see if a particular option is supported. For more information about Clang options, see the
Clang documentation.
Notices and Important Information
- The
dpcpp driver is deprecated and will be removed in a future release. For SYCL compilation, use the
-fsycl option with the C++ driver.
- In this document, you may see features labeled as experimental. An experimental feature is one that requires further testing and possible refinement. Depending on testing results, such features may be fully defined and implemented or they may be removed in a future release.
- The
Intel® oneAPI
DPC++/C++ Compiler does not support
macOS*. For
macOS or Xcode* support use Intel® C++ Compiler Classic. For more information, visit the
Intel® C++ Compiler Classic Developer Guide and Reference.
