The bwForCluster for computational and theoretical Chemistry Justus is not in live operation yet. The cluster is scheduled to enter live operation on December 5th, 2014.

1 System Architecture

The bwForCluster for computational and theoretical Chemistry Justus is a high-performance compute resource with high speed interconnect. It is intended for chemistry-related jobs with high memory (RAM,disk) needs and medium to low requirements to the node-interconnecting Infiniband network.

Overview on bwForCluster Chemistry showing only the connecting the Infiniband network. All machines are additionally connected by 1GB Ethernet.


1.1 Basic Software Features

  • Red Hat Enterprise Linux (RHEL) 7
  • Queuing System: MOAB/Torque
  • modules system


1.2 Common Hardware Features

A total of 444 compute nodes plus 10 nodes for login, admin and visualization purposes.

  • Processor: 2x Intel Xeon E5-2630v3 Prozessor (Haswell, 8-core, 2.4 GHz)
  • Two processors per node (2x8 cores)
  • 1x QDR InfiniBand HCA, single Port, Intel TrueScale

1.3 Node Types

There are three types of compute nodes, matched for increasingly less scalable and more memory-intensive (RAM and disks) jobs.

Diskless nodes SSD nodes Large Memory nodes
Quantity 224 204 16
RAM (GB) 128 128 512
Disk Space - ~1TB ~2TB
Disks - 4x 240 GB Enterprise SSD 4x 480 GB Enterprise SSD
RAID - RAID 0 RAID 0
