Detailinformation

Abbreviations:

  • p.N. - per Node
  • all CPU Codename are meant to be 'Intel', if not anything to the contrary
  • Value '#Cores per Node' mean the physical cores (not Hyperthreading 'CPUs' reported in the OS system). By default the HyperThreading is OFF on our nodes; for those few with HT=ON remarks are posted here.
 

MPI backend Systems

For testing proper start-up of MPI jobs we provide a dedicated small partition within the cluster. The Xeon Phi (KNL) nodes are not used for MPI tests by default but are also listed here as they are not integrated into SLURM.
