In October, 1999, OSC engineers installed a Cray SV1 system with 16 custom vector processors at 300MHz and 16GB of memory. The SV1 used complementary metal–oxide–semiconductor (CMOS) processors, which lowered the cost of the system, and allowed the computer to be air-cooled.
In April, 1999, OSC installed a 10-CPU IA32 Linux Cluster as a “Beowulf Cluster,” a system built of commodity off-the-shelf (COTS) components dedicated for parallel use and running an open source operating system and tool set.
Early in 1999, Pinky, a small cluster of five dual-processor Pentium II systems connected with Myrinet, was made available to OSC users on a limited basis. Pinky was named for a good-natured but feebleminded lab mouse in the animated television series Animaniacs.
OSC engineers were busy again in September of 1998, installing an SGI Origin 2000 system at the Center. The SGI Origin 2000, code named Lego, came from a family of mid-range and high-end servers developed and manufactured by Silicon Graphics Inc. (SGI) to succeed the SGI Challenge and POWER Challenge.
In November, 1997, OSC also installed two additional HPC systems, a CRAY T94 and a CRAY T3E. These systems replaced a CRAY Y-MP and a CRAY T3D, two of the Center’s most utilized systems. The T3E-600/LC housed 136 Alpha EV5 processors at 300MHz and 16GB of memory.
In November, 1997, OSC also installed two additional HPC systems, a CRAY T94 and a CRAY T3E. These systems replaced a CRAY Y-MP and a CRAY T3D, two of the Center’s most utilized systems. The T94 featured four custom vector processors at 450MHz and 1GB of memory.
In June, 1997, OSC engineers installed the Cray J90se system. This Scalar Enhanced series doubled the scalar speed of the processors on the base J90 model to 200 MHz; the vector chip remained at 100 MHz.
In October, 1995 OSC engineers installed an SGI Power Challenge system at the KRC site. The SGI system featured 16 processors, two gigabytes of main memory (8-way interleaved), and four megabytes of secondary cache.
