The default partitions are suitable for most calculations. The :test partitions are, as the name suggests, intended for shorter and smaller test runs. These have a higher priotity and a few dedicated nodes, but are limited in time and number of nodes. The :shared nodes are mainly for postprocessing. Nearly all nodes are exclusive to one job, except for the nodes in these :shared partitions.
