6.1. Intel-MPI 2021.8.0 Installation Instructions

Products that utilize Ansys Parallel Processing use MPI (message-passing interface) software. When run on a single computer, they can use the software from within their installation folders. However, if you need to use multiple computers to run a simulation, you will need to perform a separate, official install of the appropriate product software on each of the computers.

To install the Intel-MPI for use with Ansys Parallel Processing:

  1. From the Ansys Installation Launcher, click Install MPI for Ansys Parallel Processing.

  2. Click Install Intel MPI.

    A dialog box displaying the default extraction location for the Intel MPI Library Runtime Environment installation software is displayed.

  3. Verify that the extraction location is correct and then click Extract.

    The Intel MPI Library Runtime Environment Update for Windows OS Installer installation program is displayed.

  4. Click Next.

  5. Read the Software License Agreement carefully. If you agree with the license agreement, click I accept the terms of the license and then click Next.

  6. Verify the software installation destination and the components to be installed and click Next.

  7. When the installation is complete, click Finish.
