Overview
The Nexus cluster runs on a hierarchical Ethernet-based network with node-level speeds ranging anywhere from 1GbE to 100GbE. Generally speaking, newer-purchased nodes often come with hardware capable of using faster speeds, but not always. Faster speeds require increasingly more powerful/expensive network switches and cables, so some labs/centers have opted to stay with slower speeds.
In the future, SLURM's topology-aware resource allocation support may be implemented on the cluster, but it is not currently.
