Module environment (lmod)




Short introduction


HPC has a module step-system. To use some application, user needs to follow these two steps, and insert applications into the search path:

  1. Determine the machine type (eg. amp or green) by command:

    module load rocky8-spack      # for most free programs (SPACK package manager) 
    

    or

    module load rocky8/all        # for licensed programs and some free (non-SPACK managed)
    
  2. Load program needed:

    module load tau
    

The list of avalible modules can be looked by:

module avail

where:
Lic - a license is required, see user-guide for more information
Uni - commercial software with site licence, number of concurrent processes may be limited
Reg - registration required, see user-guide for more information
L - module is loaded
Dp
- deprecated (old modules, which have been superseeded by modules in the new structure)
O
- obsolete (module moved or superseeded by SPACK module)
Exp - Experimental module, used while testing software installation, module name may change or software may be deleted
D - default Module.





Long version


The module system is used to manage settings for different applications. Many applications and libraries are not in the standard search path, this way it is possible to install two different versions of the same software/library that would otherwise create conflicts. The module system is used to insert applications into the search path (or remove them from it) on a per user and per occasion basis.

Useful commands

  • All available modules can be looked through by command:

    module avail
    

    example output:

    modules

    modules are grouped in a hierarchy, there may be several versions of the same software installed, e.g. of the MPI library. Only one of these can be loaded at a single time. The default module of a group is marked by the (D), if there is only one module in a group this is the default (unmarked).

  • To load a certain version of a module/program (here - Open MPI 4.1.1-gcc-8.5.0-r8-ib):

    module load openmpi/4.1.1-gcc-8.5.0-r8-ib 
    

    To load the default module/program marked (D) (here - Open MPI 4.1.1-gcc-10.3.0-r8-tcp):

    module load openmpi/
    
  • To list all loaded modules

    module list        
    
  • Unloading a module (here - Cuda 11.3.1-gcc-10.3.0-ehi3):

    module unload cuda/11.3.1-gcc-10.3.0-ehi3
    
  • Finding a module containing a certain part (here - fem):

    module keyword fem
    

    Will be listed all modules that have “fem” in the description:

    modules

  • To find out more about a specific module (here - mfem):

    module spider mfem
    

    gives

    modules

  • The module whatis command gives you a short explanation what the software is about, e.g.

    modules

    or

    modules


Files .modulerc.lua and .bashrc

Personal preferences and resources can be specified in the files .modulerc.lua and .bashrc in the user’s $HOME directory. For example, it is possible to add a path for own module files for software installed by the user in the user’s $HOME directory, automatically load some modules on login and to define one’s own “default” modules using the entry “module_version(”r/4.1.1-gcc-10.3.0-zwgc”,”default”)” or introduce abbreviations using an entry like “module_alias(”z13”, “r/4.1.1-gcc-10.3.0-zwgc”)” to define a module alias “z13”.

examplele of .modulerc.lua file

module_version("r/4.1.1-gcc-10.3.0-zwgc","default")
module_alias("z13","r/4.1.1-gcc-10.3.0-zwgc")

module_version("p/20.2-gcc-10.3.0-python-2.7.18-ij2m","default")
module_alias("p20","p/20.2-gcc-10.3.0-python-2.7.18-ij2m")

examplele of .bashrc file

# .bashrc

# Source global definitions
if [ -f /etc/bashrc ]; then
    . /etc/bashrc
fi

# Uncomment the following line if you don't like systemctl's auto-paging feature:
# export SYSTEMD_PAGER=

# User specific aliases and functions
module load rocky8-spack
module load r/4.1.1-gcc-10.3.0-zwgc




Module groups


We moved to a new module structure! Modules from `/share/apps/modules` are being retired. Software is compiled for `x86-64` and will run o all nodes (no special optimization). Optimized versions for some software for specific nodes may follow later (or not).

New modules are grouped, you can activate them by loading one or more of the following modules:

modulegroup description
rocky8/all manually installed software
rocky8-spack software installed with spack package manager




Modules used on viz


In order to make the module system work on viz, the following needs to be added to your $HOME/.bashrc

if  [[ $(hostname -s) = viz ]]; then
   source /usr/share/lmod/6.6/init/bash
   module use /gpfs/mariana/modules/system
fi

Further access to viz and load modules needed. For example:

ssh -X -A -J UNI-ID@base.hpc.taltech.ee   UNI-ID@viz.hpc.taltech.ee

module load viz-spack
module load jmol

More about use of viz can be found at visualization page.





Available modules


Currently the following modules are available, this serves as an example, please note that the list on this page will be updated very seldom, use module avail after login to get an up-to-date list of the availabe modules.

By default SPACK builds optimized for the CPU the software is build on. The packages from the amp nodes will work on the green nodes but slower than the optimized modules. Conversely, the skylake-optimized modules will try to use hardware features not present on the green nodes, so the software will not run there.
