Queue Partitions

Queue Partitions


The CLAIX hardware is organized in the batch system as queues or partitions of nodes. Each partition consists of a collection of node types with similar specifications.

The following table shows how the various node types are organized in partitions that can be selected within Slurm.


  • 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.

(Stern) SubNUMAClustering enabled for Skylake CPUs, which means, there exist 4 NUMA nodes with 12 cores each. Slurm interpretes these NUMA nodes as sockets, therefore these nodes have 4 sockets and 12 cores per socket.

Further systems are integrated into the RWTH High Performance Computing through the Integrative hosting service.
