 The cluster is arranged in a master/slave configuration; users log into HPC (the master) and use it as a "jumping off point" to the rest of the cluster. Here's a diagram of the topology. For each server, we mention the number of CPUs and the year it was commissioned: The cluster is arranged in a master/slave configuration; users log into HPC (the master) and use it as a "jumping off point" to the rest of the cluster.
