Quarry

Quarry provides a general-purpose Unix computing environment for academic and instructional use. The Quarry cluster consists of 140 IBM HS21 Bladeservers & 230 dx340 iDataPlex servers running Red Hat Linux, with TORQUE (also called PBS) and Moab for job management and SoftEnv to simplify application and environment configuration. Quarry is a 26 teraflop system.

Each Bladesever & iDataPlex server contain two Intel Xeon 5335 quad-core processors, 8 or 16GB of memory, and gigabit Ethernet for system interconnects.  The Blade servers have a 36GB locally attached SAS disk for local scratch space and the iDataPlex servers have 160GB of locally attached SAS disk.  The Blade & dx340 rack mount configuration provides electrical power and cooling advantages that make Quarry much more cost effective while occupying much less space.
