Tthe cabling and switches used by compute nodes to communicate with each other. While necessary for every cluster, it becomes particularly important with highly parallel computing, where calculations are split among nodes to be solved simultaneously. The three primary configurations we recommend to our customers are standard gigabit Ethernet, 10GbE (short for “10 gigabit Ethernet”) and InfiniBand. While processor speed, memory amount and number of nodes in your cluster are important, interconnect is an important onsideration for overall cluster performance
