Installation

New Installations

The Intel® MPI Library is part of the Intel® 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 directly or visit the HPC Kit product page for information on downloading a stand-alone or runtime version of the Intel MPI Library.

Upgrading

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

To start installation, run intel-mpi-<version>.<package-num>.sh or intel-mpi-<version>.<package-num>_offline.sh. The default installation path for the Intel MPI Library is /opt/intel/compilers_and_libraries_<version>.<package-num>/linux/mpi.

There are two different installations:

  • RPM-based installation - this installation requires root password. The product can be installed either on a shared file system or on each node of your cluster.
  • Non-RPM installation - this installation does not require root access and it installs all scripts, libraries, and files in the desired directory (usually $HOME for the user).

Scripts, include files and libraries for different architectures, are located in different directories. By default, you can find binary files and all needed scripts under the <install-dir> directory.
