Overview of Hansen

Hansen was a compute cluster operated by ITaP and a member of Purdue's Community Cluster Program. Hansen went into production on September 15, 2011. Hansen consisted of Dell compute nodes with four 12-core AMD Opteron 6176 processors (48 cores per node) and either 96 GB, 192 GB, or 512 GB of memory. All nodes had 10 Gigabit Ethernet interconnects and a 5-year warranty. Hansen was decommissioned on October 1, 2016.

Sub-Cluster Number of Nodes Processors per Node Cores per Node Memory per Node Interconnect TeraFLOPS
Hansen-A 103 Four 2.3 GHz 12-Core AMD Opteron 6176 48 96 GB 10 GigE 48.8
Hansen-B 93 Four 2.3 GHz 12-Core AMD Opteron 6176 48 192 GB 10 GigE 40.2
Hansen-C 5 Four 2.3 GHz 12-Core AMD Opteron 6176 48 512 GB 10 GigE 0.9

Hansen nodes ran Red Hat Enterprise Linux 6 (RHEL6) and used Moab Workload Manager 8 and TORQUE Resource Manager 5 as the portable batch system (PBS) for resource and job management.
