Hardware specifications of cluster compute nodes

  • The LUIS computing cluster is a heterogeneous general purpose system designed for a variety of workloads.
  • We currently run two separate scheduling/batch systems, Maui/PBS/Torque and SLURM. We will gradually move partitions running under Maui/PBS to SLURM.
  • By policy, compute nodes cannot access the internet. If you need an exception to this rule, contact cluster support with information about the IP address, port number(s) and protocol(s) needed as well as the duration and a contact person. Please note that the IP address must belong to the university network.
  • Job can have a maximum duration of 200 hours, and a user will not have more than 64 (or 768 CPU cores) running simultaneously and 2000 jobs in the queue at any given moment.
  • All nodes in a sub-cluster are interconnected using Mellanox Infiniband (at least QDR) non-blocking fat tree network.
  • NFS based HOME (for home directories) and Lustre based BIGWORK (for temporary files during computations) storage systems are available on all compute nodes.
  • The line “FCH” in this table aggregates all the nodes we run for various institutes of the LUH under the conditions of the service "Forschungsclusterhousing". They contribute significant additional power to the cluster, usually during the night and over the weekend, but are usually reserved exclusively for institute accounts on week days. This model also means that your jobs have a high chance of running in the night, when they request less than 12 hours of walltime, or during weekends, for jobs that request less than 60 hours.
