Examples
Example 1
To get a list of available MPI implementations:
user $source selector-mpi -sExample 2
To get a list of package versions available for the gnu-openmpi MPI implementation:
user $source selector-mpi -i gnu-openmpi -sExample 3
To use lammps version 20170101, qe version 5.0.2, and the default version for all other available packages for the gnu-openmpi MPI implementation:
user $source selector-mpi -i gnu-openmpi lammps/20170101 qe/5.0.2Example 4
To use Open MPI compiled with the GNU compiler and the default version of all packages, add the following line to the bottom of the $HOME/.bashrc file:
source selector-mpi -i gnu-openmpi -f -qIt is recommended to put (4) into all queue submission scripts to be sure which MPI implementation and package version is used.
