Overview

Description

Depending on the hardware equipment and the age of a cluster there is always a set of typical applications that fit the cluster capabilities. The idea is to run any calculation on a cluster that just fits the job requirements; running it on less capable cluster would slow down the calculation or prevent running it at all, starting a low-demanding job on highly equippped cluster would waste the resources and prevent running jobs that require such equipment.

Clusters

The following text provides detailed information about clusters and nodes. Tables show resources available for calculations, which are usually smaller than total resources mentioned in the general overview above; some of the total node memory (RAM) must always remain reserved for operating system tasks.
