How to search mpi module available to load in Linux cluster?

To find the module to load Linux cluster, we need to type

module spider module_name_key
module_name_key is the partial name which we can use for searching.
it will bring us the modules which are available for us to load.
For example,
I wanted to load openmpi module from the Linux cluster. So I need to know the exact name of mpi module of the cluster. I search it by
module spider openmpi

it showed me the openmpi modules which are available for loading.

For detailed information about a specific "OpenMPI" module (including how to load the modules) use the module's full name.


Suppose, we want to load the module OpenMPI/1.6.4-GCC-4.7.2

We need to load the module by this command

module load OpenMPI/1.6.4-GCC-4.7.2

By typing the following command I can check the module list in the cluster.


module list

It will show you the list which is loaded for you in the cluster.

To be specific


$ module list

Currently Loaded Modules:
1) shared 2) rc-base 3) DefaultModules 4) gcc/8.2.0 5) slurm/18.08.9 6) mpich/ge/gcc/64/3.3

$ module load OpenMPI/1.6.4-GCC-4.7.2
$ module list

Currently Loaded Modules:
1) shared 3) DefaultModules 5) slurm/18.08.9 7) GCC/4.7.2 9) OpenMPI/1.6.4-GCC-4.7.2
2) rc-base 4) gcc/8.2.0 6) mpich/ge/gcc/64/3.3 8) hwloc/1.6.2-GCC-4.7.2
