摘要: This article assess the state-of-the-art technology in massively parallel processors (MPPs) and clusters of workstations (COWs) for scalable computing. We evaluate IBM SP2, Intel Paragon, Cray T3D/T3E, ASCI TeraFLOPS system recently proposed by Intel. The concept scalability is characterized from several orthogonal dimensions. Scalable performance attributes are discussed context a newly computer model.
