Cluster

A set of computers linked to each other in such a way that their resources can be collectively pooled together on computational jobs. “Cluster” is not a term exclusive to HPC (there are, for example, Kubernetes clusters that are multiple computers configured to run a Kubernetes instance together), but in the case of HPC, the word typically refers to a Beowulf-style cluster for specific industrial computing applications. Clusters in any form are commonly just called a “cluster” without modifier.
