Environment Modules - eX3 - Experimental Infrastructure for Exploration of Exascale Computing

eX3 uses environment modules to manage reusable version of different software packages. The documentation is extensive, so advanced users are asked to consult the official documentation for details. In particular the cookbook will be interesting for advanced users, e.g., to create their own module files.

Here, we only highlight basic usage and eX3 specific elements and recommended practices.

Basic commands¶

To know what is already loaded:

$> module list
Currently Loaded Modulefiles:
 1) slurm/slurm/21.08.8   2) rustc/1.85.1(default)   3) cuda12.9/toolkit/12.9.1   4) hwloc/gcc/2.12.2+cu129   5) hwloc/gcc/2.12.2-base

To search for available modules (by pattern, here ‘cuda’):

$> module avail cuda
module avail cuda
--------------------------------------------------------------------------------------------------------- /cm/shared/modulefiles ----------------------------------------------------------------------------------------------------------
cuda9.2.OLD/toolkit/9.2.148  cuda10.1/profiler/10.1.243 ...
...
cuda10.1/nsight/10.1.243 ...

To load a module

$> module load julia/1.11.4

or likewise to unload:

$> module unload julia/1.11.4
