Installation

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#>/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
<installdir>
 directory.
