Abstract
The SGI Origin 2000 is a cache-coherent non-uniform memory access IccNUMA) tnultionxessor desipned and manufactured bv Silicon ‘Graphics,. Inc.?he Origin sys;m was desi&d from th> ground up as a multiprocessor capable of scaling to both small and large processor counts without any bandwidth, latency, or cost cliffs.The Origin system consists of up to 512 nodes interconnected by a scalable Craylink network Each node consists of one or two RIO000 processors, up to 4 GB of coherent memory, and a connec-tion to a portion of the XI0 IO subsystem. This paper discusses the motivation for building the Origin 2000 and then describes its ar-chitecture and implementation. In addition, performance results are presented for the NAS Parallel Benchmarks V2.2 and the SPLASH2 applications. Finally, the Origin system is compared to other contemporary commercial ccNUMA systems. 1
