Silicon Graphics/Cray Research has set two new world records for SPECrate performance. The 128-processor CRAY Origin2000 systems achieved a SPECrate_fp95 peak result of 18,027, more than three times the performance of any other shared-memory architecture system. The SPECrate_int95 peak result of 11,335 doubled the previous world record held by the Origin series.What is significant is the fact that the two records were achieved within a 128-processor Single-System Image (SSI) 64-bit UNIX operating environment. This SSI environment provides global shared access to all system resources and allows for efficient workload scheduling and simplified system management."These SPECrate benchmarks are meaningful," says James Chiweshe, Managing Director of Silicon Graphics sub-Saharan Africa, "because they are extremely accurate indicators of actual application performance, as opposed to being just another esoteric benchmark test. The top-rate results are impressive proof of the real world advantages of the Origin series S2MP architecture."Indicating the near-linear scalability of the Origin line, the 128-processor CRAY Origin2000 scored nearly double the marks recorded last November by a 64-processor Origin2000 system. This server line provides a building-block approach scaling from 1- to 128-processor configurations and leads the industry in performance, bandwidth, I/O, scalability and cost structure. The cc-NUMA Origin architecture has the best features of shared-memory processing, distributed-memory parallel processing and clusters, because of the combination of high-bandwidth, low-latency CrayLink interconnect technology and the scalable IRIX operating environment. This merger of technologies into a single-system design sets the stage for the next decade of computing.
