Abstract
The SGI Origin 200/2000 is a cache-coherent non-uniform memory access (ccNUMA) multiprocessor, designed and manufactured by Silicon Graphics Inc. (SGI). The Origin system was designed from the ground up as a multiprocessor that was capable of scaling to both small and large processor counts without any cost, bandwidth or latency cliffs. The Origin system consists of up to 512 nodes interconnected by a highly scalable Craylink network. Each node consists of one or two R10000 processors and up to 4 GBytes of coherent memory. Each node also connects to the scalable XIO I/O subsystem. This paper discusses the motivation for building the Origin 200/2000 and describes its architecture and implementation.Keywords
