Overview

General 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.

Cluster survey
