Module system

HPC facilities provide a user friendly environment to manage a large number of codes and versions of those codes, on this cluster, we have lmod module system available to manage the user environment. To see the codes that are available, the module command is available:

 $ module avail
  --------------------------------- /usr/share/modulefiles --------------------------------------------------------------------
  mpi/openmpi-x86_64

  -------------------------------- /opt/ohpc/pub/modulefiles ------------------------------------------------------------------
  applications/gpu/gromacs/2024.4    applications/gpu/qespresso/7.3.1

the module system also provide a set of additional commands for managing modules: module load to activate an environment:

   module load applications/gpu/gromacs/2024.4

Module unload:

   module unload applications/gpu/gromacs/2024.4

module purge:

   module purge

and module list, to show loaded modules

   module list
