OSC engineers in 1995 installed a Convex Exemplar SPP1220 system, a recently upgraded version of Convex’s popular SPP1000 system, featuring a new processor, memory and I/O package.
In April, 1995, OSC engineers began installing a powerful new computer at the OSC/KRC – an IBM RISC System/6000* Scalable POWERparallel Systems * SP2.
In 1994 OSC installed a Cray Y-MP 2E as a complement machine to the Cray T3D MPP.
On April 18, 1994, OSC engineers took delivery of a 32-processor Cray T3D MPP, an entry-level massively parallel processing system. Each of the processors included a DEC Alpha chip, eight megawords of memory and Cray-designed memory logic.
In August 1989, OSC engineers completed the installation of the $22 million Cray Y-MP8/864 system, which was deemed the largest and fastest supercomputer in the world for a short time. The seven-ton system was able to calculate 200 times faster than many mainframes at that time and underwent several weeks of stress testing from “friendly users, who loaded the machine to 97 percent capacity for 17 consecutive days.
Ohio State in the spring of 1987 budgeted $8.2 million over the next five years to lease a Cray X-MP/24, OSP’s first real supercomputer. The X-MP arrived June 1 at the OSU IRCC loading dock on Kinnear Road.
OSC has operated a number of supercomputer systems over the years. Here is a list of previous machines and their specifications.

Batch requests are handled by the TORQUE resource manager and Moab Scheduler as on the Oakley and Glenn systems. Use the
qsub command to submit a batch request,
qstat to view the status of your requests, and
qdel to delete unwanted requests. For more information, see the manual pages for each command.
There are some changes for Ruby, they are listed here:
