Before you start using Intel® MPI Library, complete the following steps:
- To establish the proper environment settings, source the mpivars.[c]sh script. It is located in the <installdir_MPI>/intel64/bin directory, where <installdir_MPI> refers to the Intel MPI Library installation directory.
- Create a hosts file that lists the nodes in the cluster. In the text file, use one host name per line. For example:
- Make sure to establish an SSH connection without a password among all nodes in the cluster. This ensures proper communication of MPI processes among the nodes. To establish the connection, use the sshconnectivity.exp script located at <installdir>/parallel_studio_xe_<version>.<update>.<package>/bin.
After completing these steps, you are ready to use Intel MPI Library.
