What is a cluster?

Cluster systems are made up of multiple computers, connected together to act as one. Each computer is called a node in the cluster and can and can have multiple processors (called cores).  Users log in to the cluster through a limited number of login/head nodes and submit jobs to the many compute nodes.  These systems are inherently parallel and can be greatly beneficial when your jobs are also parallelized.
