Configuring a Microsoft Visual Studio* Project

NOTE:
Starting with Intel(R) MPI 2021.11, the I_MPI_ONEAPI_PATH variable is deprecated. Use the absolute installation path instead: C:\Program Files (x86)\Intel\oneAPI\mpi\<version>\.

To configure a Microsoft Visual Studio* project with Intel® MPI Library, do the following:

  1. In Microsoft Visual Studio*, create a console application project or open an existing one.

  2. Open the project properties, go to Configuration Properties > Debugging and set the following parameters:

    Command: <installation_directory>\bin\mpiexec.exe

    Command arguments: -n <processes-number> "$(TargetPath)"

    Environment for the Debug version: PATH=<installation_directory>\bin\mpi\debug;<installation_directory>\opt\mpi\libfabric\bin;$(PATH)

    Environment for the Release version: PATH=<installation_directory>\bin;<installation_directory>\opt\mpi\libfabric\bin;$(PATH)

    NOTE:
    Starting with Intel(R) MPI 2021.11, the <installation_directory>\bin\mpi\release and <installation_directory>\lib\mpi\release directories are deprecated. Use the corresponding <installation_directory>\bin\mpi\debug and <installation_directory>\lib\mpi\debug directories instead.

  3. In Configuration Properties > C/C++ or Fortran, as appropriate, set the following parameter:

    Additional Include Directories: <installation_directory>\include

  4. In Configuration Properties > Linker, set the following parameter:

    Additional Library Directories for the Debug version: <installation_directory>\lib\mpi\debug;<installation_directory>\lib

    Additional Library Directories for the Release version: <installation_directory>\lib

  5. In Configuration Properties > Linker > Input, set the following parameters:

    • For Fortran, set Additional Dependencies: impi.lib
    • For C++, set Additional Dependencies: impi.lib and impicxx.lib

After completing these steps, you can build the solution and run the application. To run the application from Visual Studio, you can use the Ctrl + F5 key combination (Start Without Debugging). For other available options, see Running Applications.
