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.

Sub-Cluster Number of Nodes Processors per Node Cores per Node Memory per Node Retired in
A 392 Two 2.1 GHz 12-Core AMD 6172 24 48 GB 2015
B 40 Two 2.1 GHz 12-Core AMD 6172 24 96 GB 2015
C 2 Two 2.1 GHz 12-Core AMD 6172 24 192 GB 2015
D 4 Two 2.1 GHz 12-Core AMD 6172 24 192 GB 2015

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 would otherwise be idle. The application of operating system patches occurred as security needs dictated. All nodes allowed for unlimited stack usage, as well as unlimited core dump size (though disk space and server quotas were still a limiting factor).

Rossmann Namesake

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 Rossmann.
