Invoke the Compiler

The Intel® oneAPI C++ Compiler is invoked using
icpx
 (Linux*) or
icx
 (Windows*). The Intel® oneAPI DPC++ Compiler is invoked using
dpcpp
.
For more information, see Invoking the Compiler in the
Intel® oneAPI
DPC++/C++
 Compiler
 Developer Guide and Reference
.
To enable OpenMP* offloading for C++ applications, invoke the compiler with:
  • icpx -fiopenmp -fopenmp-targets=<arch>
     (Linux)
  • icx /Qiopenmp /Qopenmp-targets:<arch>
     (Windows).
To enable OpenMP offloading for DPC++ applications, invoke the compiler with:
  • dpcpp -fiopenmp -fopenmp-targets=<arch>
     (Linux)
  • dpcpp /Qiopenmp /Qopenmp-targets:<arch>
     (Windows)
For more information about options, you can go to the option descriptions found in the Compiler Options section of the
Intel® oneAPI
DPC++/C++
 Compiler
 Developer Guide and Reference
.
The
dpcpp
 driver has different compatibilities on different OS hosts. Linux provides GCC*-style command line options and Windows provides Microsoft Visual C++* compatibility with Microsoft Visual Studio*.
  • It recognizes GCC-style command line options (starting with “-“) and can be useful for projects that share a build system across multiple operating systems.
  • It recognizes Windows command line options (starting with “/”) and can be useful for Microsoft Visual Studio-based projects.
