The SGI Origin 2000 is a cache-coherent non-uniform memory access (ccNUMA) multiprocessor designed and manufactured by Silicon Graphics, Inc. The Origin system was designed from the 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 5 1 2 nodes interconnected by a scalable Craylink network. Each node consists of one or two RlOOOO processors, up to 4 GB of coherent memory,

In addition, performance results are presented for the NAS Parallel Benchmarks V 2 . 2 and the SPLASH2 applications. Finally, the Origin system is compared to other contemporary commercial ccNUMA systems.
