Cluster Simulations

For PyroSim 2015.3 and more recent, you will install PyroSim on every node you want to use in the cluster. You do not need to activate the software on these computers if you do not intend to run the PyroSim program on them. The installation alone will setup the computer to be available for cluster simulations.
