Using Modulefiles

Using modulefiles is very simple. Keep in mind that the below commands will work anywhere on the cluster, so you can load/unload modules within your slurm submission scripts or during interactive jobs. This is what they are intended for.

List All Available Modules

module av

which will return an output that looks something like this:

------------------------------------------------- /modules/modulefiles -------------------------------------------------
   R/3.6.2             cuda/10.1.243 (D)    gcc/9.2.0               julia/1.1.1         openmpi/4.0.4
   cmake/3.7.2         cuda/11.0.1          glxgears/1.0            jupyter/3.6.8       python/2.7.16

Note

The output above is subject to change.

Searching for Modules

module av gcc

That will only show you the available gcc modules.

Loading Modules

module load gcc/9.2.0

Note

The convention is <app name>/<app version>.

After loading a module, you can test is out by running whereis gcc, which will show you which gcc will be executed.

Unloading Modules

module unload gcc

Unloading All Modules

module purge
