Hardware

The cluster consists of 36 separate computers, called nodes,  and other hardware, all mounted in two 19" racks. The cluster has total of 72 CPUs, 72GB memory, and about 2TB of disks.

Master node: 2 Pentium-III processors 933MHz, 2GB memory, Tyan S2567 motherboard, mirrored 36GB 160 SCSI IBM Ultrastar disks, CD-ROM, floppy disk
35 compute nodes: 2 Pentium-III processors 933MHz, 2GB memory, Supermicro 370DER motherboard, 18GB 160 SCSI IBM Ultrastar disk, floppy disk
Mass storage: 1TB disk array (8 Seagate Barracuda 180GB disks 160 SCSI: striped and mirrored > 80MB/s sustained throughput), VXA Autopak-30 tape library.
Management interconnect: 100Mb/s switched Ethernet with 1Gb/s fiber uplink to master node
Compute interconnect: SCI Dolphin , 6x6 double torus, 220MB/s actual bandwidth, 5us latency
Power management: 4 APC Smart UPS 2200 with temperature sensors and network interface. Total power consumption about 5kW idle and 8kW fully loaded.
Console management: Serial console through 3 Perle IOLAN+ terminal servers
