Overview of Rossmann

Rossmann was a compute cluster operated by ITaP and was a member of Purdue's Community Cluster Program. Rossmann went into production on September 1, 2010. It consisted of HP (Hewlett Packard) ProLiant DL165 G7 nodes with 64-bit, dual 12-core AMD Opteron 6172 processors (24 cores per node) and 48 GB, 96 GB, or 192 GB of memory. All nodes had 10 Gigabit Ethernet interconnects and a 5-year warranty. Rossmann was decommissioned on November 2nd, 2015.


Rossmann is named in honor of Michael Rossmann, Purdue's Hanley Distinguished Professor of Biological Sciences. More information about his life and impact on Purdue is available in an ITaP Biography of Michael Rossmann.

Rossmann consisted of five logical sub-clusters, each with a different memory/storage configuration. All nodes in the cluster had dual 12-core AMD Opteron 6172 processors and 10 Gigabit Ethernet (10GigE).

Detailed Hardware Specification

Sub-Cluster Number of Nodes Processors per Node Cores per Node Memory per Node Interconnect Disk
Rossmann-A 392 Two 2.1 GHz 12-Core AMD 6172 24 48 GB 10 GigE 250 GB
Rossmann-B 40 Two 2.1 GHz 12-Core AMD 6172 24 96 GB 10 GigE 250 GB
Rossmann-C 2 Two 2.1 GHz 12-Core AMD 6172 24 192 GB 10 GigE 1 TB
Rossmann-D 4 Two 2.1 GHz 12-Core AMD 6172 24 192 GB 10 GigE 2 TB

Rossmann 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. Rossmann also ran jobs for BoilerGrid whenever processor cores in it were otherwise idle.
