The Intel® MPI Library is part of the Intel® oneAPI HPC Toolkit (HPC Kit), which includes a variety of tools to help you build, analyze, and deploy HPC applications. You can download the HPC Kit here, or visit the HPC Kit product page for information on downloading a stand-alone or runtime version of the Intel MPI Library.


If you have a previous version of the Intel® MPI Library for Windows* OS installed, you do not need to uninstall it before installing a newer version.

To install the Intel MPI Library, double-click on the distribution file w_mpi_oneapi_p_<version>.<package-num>.exe.

You will be asked to choose a directory in which the contents of the self-extracting installation file will be placed before the actual installation begins. After installation, the files will still be located in this directory. By default, C:\Program Files (x86)\Intel\Download is used on machines with Intel® 64 architecture.

Follow the prompts outlined by the installation wizard to complete the installation.

You need domain administrator rights when you install the Intel® MPI Library on the Microsoft Windows* OS. Otherwise, you cannot proceed with the Active Directory* setup. See the Intel® MPI Library Developer Reference for more Active Directory setup information.
