Meaning – A cluster is a group of interconnected computers, that work together to complete certain tasks. These tasks are usually computational intensive and require such a cluster in order to perform to the level that is desired.

In a cluster, each individual computer is referred to as a node.

Each node contains one or more processors or CPUs (usually two) on which computation takes place.  Each processor has multiple “cores”. A job can be run on a single core, unless it has been written in such a way that multiple cores or multiple nodes are required.

The nodes in each  clusters are connected to one-another by high-speed, low-latency networks, which helps to support parallel operations across nodes.

Example of usage“The admin was tasked with overseeing the operation of the cluster within the organisation, and report any errors or discrepancies.”
