URSA

URSA.gsu.edu - basic info

URSA is a 576 core Super Computer based on the Power5+ processor and IBM's P series architecture. (More details.) The system has 18 TB user disk storage with backups.

URSA has 36 nodes each with 8 dual-core processors. Thirty-four nodes have 32 GB RAM; one node has the maximum memory of 256 GB; and one node has 64 GB. Within each node we have SMP options available and between the nodes we have a Brocade high speed interconnect (IBM pSeries High Performance Switch). Also implemented is IBM's Parallel Environment (an MPI utility designed for the pSeries architecture with features like remote memory access).

Attached to the nodes is a 18 TB SAN (Storage Area Network) via a fiber SAN switch. The SAN is implemented using IBM GPFS (General Parallel File System http://www-03.ibm.com/systems/clusters/software/gpfs.html) and is accessed via a DS4800 raid controller. The SAN environment is made up of 16 300GB fiber channel disks behind redundant 2GB/s controllers. "Large Page" support is currently turned on in the SAN and can be configured in a number of ways to meet fast data access needs.
