Work with Environment Modules

Set up the working environment for each package using the module command. The module command will activate dependent modules if there are any.

To show currently loaded modules: (These modules are loaded by default system configurations)

-bash-4.2$ module list

Currently Loaded Modules:
  1) autotools   3) gnu12/12.2.0   5) ucx/1.11.2         7) openmpi4/4.1.4
  2) prun/2.2    4) hwloc/2.7.0    6) libfabric/1.13.0   8) ohpc

To show all available modules:

-bash-4.2$ module avail

To load a module and verify:

-bash-4.2$ module load R
-bash-4.2$ module list
