Cross-Architecture Compiling

  • Development Productivity: Targets CPUs and accelerators through single-source code while permitting custom tuning
  • Language Standards Support: Is built to the latest standards, including C++ 17 and SYCL†, and initial support for C++ 20, to ensure portability and support of features like generic lambda expressions and variable templates
  • Industry Standards Support: Supports a subset of OpenMP 4.5, 5.0, and 5.1 for GPU offload†
  • Trusted Technology: Uses well-proven LLVM compiler technology as well as Intel's history of compiler leadership

†Available in the Intel oneAPI DPC++/C++ Compiler only.
