Hansen is named in honor of Arthur G. Hansen, former Purdue president and alumnus and supercomputing proponent. More information about his life and impact on Purdue is available in an ITaP Biography of Arthur G. Hansen.
Hansen consisted of three logical sub-clusters, each with a different amount of memory. Hansen-A nodes had 96 GB RAM; Hansen-B, 192 GB RAM; Hansen-C, 512 GB RAM. All nodes had 10 Gigabit Ethernet interconnects.
|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 use Moab Workload Manager 8 and TORQUE Resource Manager 5 as the portable batch system (PBS) for resource and job management. Hansen also ran jobs for BoilerGrid whenever processor cores in it would otherwise be idle.
