Editing ASCI Red (section)

== Technical specifications ==

The computer itself took up almost {{convert|1600|sqft}} of space,<ref name=MIT/> and was made up of 104 "cabinets". Of those cabinets, 76 are computers (processors), 8 are switches, and 20 are disks. It had a total of 1212 GB of RAM, and 9298 separate processors.
The original machine used Intel Pentium Pro processors each clocked at 200&nbsp;MHz. These were later upgraded to specially packaged Pentium II Xeon processors, each clocked at 333&nbsp;MHz. Overall, it required 850&nbsp;kW of power (not including air conditioning).  What sets ASCI Option Red aside from all of its predecessors in supercomputing is its high [[input/output|I/O]] [[Bandwidth (computing)|bandwidth]]. Previous supercomputers had multi-[[GFLOPS]] performance, yet their slow I/O speeds would slow down, or bottleneck the systems. Intel's TFLOPS [[List of file systems#Distributed parallel file systems|PFS]] is an extremely efficient "Parallel File System" that can sustain transfer speeds of up to 1 GB/s, eliminating bottlenecks.<ref name="PFS">{{cite book|last=Garg|first=Sharad|chapter=TFLOPS PFS: Architecture and Design of A Highly Efficient Parallel File System |publisher=IEEE|doi=10.1109/SC.1998.10003|title=Proceedings of the IEEE/ACM SC98 Conference|pages=2|year=1998|isbn=0-8186-8707-X|s2cid=8683745 }}</ref>
