[Beowulf] HPC and Licensed Software

[Skylar Thompson]

Back when we had software requiring MathLM/FlexLM, we just used NAT to get
the cluster nodes talking to the licensing server. We also had a consumable
in Grid Engine so that people could keep their jobs queued if there were no
licenses available.
