[slurm-users] Using "Environment Modules"

[Brian Andrus]

That flow is fairly common.

Basically, you need to get the environment alias 'module' to be defined 
so you need your script to source things.

The common thing is to:

     source ~/.bash_profile

On default RHEL-based systems this will also call ~/.bashrc which in 
turn calls ~/etc/bashrc

The net effect is that the environment gets setup the same as if the 
user had opened a shell console.
