In December, 2003, OSC engineers installed a 512-CPU Pentium 4 Linux Cluster. Replacing the AMD Athlon cluster, the P4 doubled the existing system’s power with a sizable increase in speed. With a theoretical peak of 2,457 gigaflops, the P4 cluster contained 256 dual-processor Pentium IV Xeon systems with four gigabytes of memory per node and 20 terabytes of aggregate disk space.
In September, 2003, OSC engineers installed a SGI Altix 3700 system to replace its SGI Origin 2000 system and to augment its HP Itanium 2 Cluster. The Altix was a non-uniform memory access system with 32 Itanium processors and 64 gigabytes of memory. The Altix featured Itanium 2 processors and runs the Linux operating system. OSC's HP Cluster also included Itanium 2 processors and runs Linux.
OSC engineers in March, 2002, installed a 256-CPU AMD Linux Cluster. The 32-bit Parallel Processing (MPP) system featured one gigabyte of distributed memory, 256 1.4 & 1.53 gigahertz AMD Athlon processors and a Myrinet and Fast Ethernet interconnect.
