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 <installdir>/intel64 directory.
