[slurm-users] Slurm and available libraries

[Ole Holm Nielsen]

I can highly recommend EasyBuild as an easy way to provide software 
packages as "modules" to your cluster.  We have been very pleased with 
EasyBuild in our cluster.

I made some notes about installing EasyBuild in a Wiki page:
   https://wiki.fysik.dtu.dk/niflheim/EasyBuild_modules
We use CentOS 7 Linux.

Also, if you want information about Slurm setup, I have written another 
set of Wiki pages:
