Notes on Compiler Commands

  • Compiler commands are available only in the Intel MPI Library Software Development Kit (SDK).
  • For the supported versions of the listed compilers, refer to the Intel® MPI Library System Requirements.
  • To display mini-help of a compiler command, execute it without any parameters.
  • Compiler wrapper scripts are located in the <install-dir>\bin directory.
  • The environment settings can be established by running the <install-dir>\env\vars.bat file. To use a specific library configuration, pass the release or debug arguments to the script to switch to the corresponding configuration. The ordinary multi-threaded optimized library is chosen by default. Alternatively, you can use the I_MPI_LIBRARY_KIND environment variable to specify a configuration and source the script without arguments.
  • Ensure that the corresponding underlying compiler is already in your PATH. If you use Intel® compilers, run the vars.bat file from the installation directory to set up the compiler environment.
