New Installations

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.

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.
Extract the
l_mpi[-rt]_p_<
version
>.<
package-num
>.tar.gz
 package by using following command: 
$ tar -xvzf l_mpi[-rt]_p_<version>.<package-num>.tar.gz
This command creates the subdirectory
l_mpi[-rt]_p_<
version
>.<
package-num
>
.
To start installation, run
install.sh
. The default installation path for the Intel MPI Library is
/opt/intel/compilers_and_libraries_<
version
>.<
update
>.<
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.
