Which partition to choose?
If you do not request a partition, you will be placed on to the default partition, which is standard96 in Berlin and medium40 in Göttingen.
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. Shared nodes are suitable for post-processing. A job running on a shared node is only accounted for its core fraction (cores of job / all cores per node). All non shared nodes are exclusive to one job, which implies that full NPL are paid.
Details about the CPU/GPU types and network topology can be found here.
