Overview of Coates
Coates is named in honor of Ben Coates, former head of Electrical Engineering and founder of both the Computer Engineering degree program and the Engineering Computer Network (ECN) at Purdue. More information about his life and impact on Purdue is available in an ITaP Biography of Ben Coates.
Coates consisted of five logical sub-clusters, each with a different memory/storage configuration as described in the following table. All nodes in the cluster featured 10 Gigabit Ethernet (10GigE).
|Sub-Cluster||Number of Nodes||Processors per Node||Cores per Node||Memory per Node||Interconnect||Disk|
|Coates-A||640||Two 2.5 GHz Quad-Core AMD 2380||8||32 GB||10 GigE||500 GB|
|Coates-B||45||Two 2.5 GHz Quad-Core AMD 2380||8||32 GB||10 GigE||2 TB|
|Coates-C||264||Two 2.5 GHz Quad-Core AMD 2380||8||16 GB||10 GigE||500 GB|
|Coates-D||33||Two 2.5 GHz Quad-Core AMD 2380||8||16 GB||10 GigE||2 TB|
|Coates-E||11||Four 2.5 GHz Quad-Core AMD 8380||16||128 GB||10 GigE||2 TB|
Coates nodes ran Red Hat Enterprise Linux 5 (RHEL5) and used Moab Workload Manager 7 and TORQUE Resource Manager 4 as the portable batch system (PBS) for resource and job management. Coates also ran jobs for BoilerGrid whenever processor cores in it would otherwise have been idle.
