Thanks for the info. This is actually good. I've actually been using module 
environment on the cluster but never actually set those up myself. I just 
didn't realize F12 is moving in that direction too. I am trying to get my code 
to compile locally on my workstation for development / debugging. Having 
module environment on F12 is actually good because I'm just thinking about 
setting up different MPI & compilers to try. Now I just need to learn how to 
use and set up those modules. Thanks again for the info.
