We have three distinct compute clusters.
nscc.colby.edu is the production HPC cluster.
schupflab.colby.edu is a student accessible teaching cluster for limited jobs,
and the CompSci clusters (the dwarves) are research clusters aimed at running the latest software (OS Fedora 24) and GPUs supported by Cuda release 7.5 on OS Centos 7.
