Software Modules

Software Modules are designed to manage software installed on our Linux systems. This allows us to provide a wide range of software across all our servers so that you don't have to install software on your own. We also offer different versions of software, letting users choose which they want to use.

Type module avail to get a list of available software.

Load the software module usingmodule load. Now the software is ready to use.

pgh5a@portal04 ~ $ module load python3              # Load the module for use in your current session
pgh5a@portal04 ~ $ which python
/sw/centos/python/3.6.2/bin/python
pgh5a@portal04 ~ $ python                           # When you run `python` you get the version that has been loaded
Python 3.6.2 (default, Oct  6 2017, 13:03:05) 
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>

module list will show what modules you have loaded.

pgh5a@portal ~ $ module load matlab
pgh5a@portal ~ $ module load php
pgh5a@portal ~ $ module list
Currently Loaded Modulefiles:
  1) matlab    2) python3   3) php

module display will show specific information about the environment variables setup by a module.

pgh5a@portal ~ $ module display python

/sw/centos/Modules/modulefiles/python:

pgh5a@portal ~ $ echo $LD_LIBRARY_PATH

Use module switch to change one version of software for another and module unload to unload modules when you are done or no longer want this software.

pgh5a@portal ~ $ module switch python3 python2
pgh5a@portal ~ $ module unload php

Shell Scripting/Slurm Batch

If you write shell scripts or slurm batch files that make use of these software packages, remember that you must still load modules from inside of your script. For example, your script must contain the line module load python3 before you can use python from inside of your script.

Initialize Modules System

To make modules work from inside SLURM or scripts, you must including the following line in your script before loading any modules:

source /etc/profile.d/modules.sh
