Installing Intel® MPI Library

If you have a previous version of the Intel® MPI Library for Linux* OS installed, you do not need to uninstall it before installing the latest 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_2016.<update>.<package#>/linux/mpi.

There are 2 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>/<arch> directory. For example, for Intel®64 architecture, <arch> is bin64.

Note

To use the full functionality of the library on Intel®64 architecture, set the environment from the <installdir>/bin64 directory. You can use the provided script files to simplify setting the environment variables. Source the file <installdir>/bin[64]/mpivars.[c]sh to set appropriate values for your desired development environment.

For more information on installation, see Intel® MPI Library for Linux* OS Installation Guide. You can also find information about how to install the product in silent mode and some useful installer options.
