Compute Nodes

This is an (incomplete) list of the hardware specs for the compute nodes which are currently used in the MOGON cluster.

This page describes the technical values for most nodes. These, particular with regard to the available memory, are not to be confused with the available RAM (as we need some memory for otherwise neglegible services such as the operating system, the parallel file system, the scheduler, …). Information on the partitions and available ressources can be found here.

These are the generally available nodes of MOGON II:

For access to the DGX-nodes you have to contact as at
The z nodes contain the so-called broadwell architecture, the x nodes the skylake architecture. Both can be selected upon job submission with the -C/–constraint flag to sbatch. See our submit page for further info.
