DescriptionFrom University Video Communications' catalog:
"Distributed shared-memory (DSM) systems offer the advantages of the shared-memory programming model while eliminating the bottleneck of traditional SMP systems. The enabling technologies for DSM systems are directory-based cache coherence and scalable interconnection networks. Silicon Graphics' S2MP architecture and Origin servers provide high-performance and a seamless shared-memory programming model that scales from deskside uniprocessors to 1024-processor supercomputers. This talk begins with an introduction to distributed shared-memory and directory-based cache coherence. A technical overview of SGI's Origin is then given. The design trade-offs made in the processor interface, node design, interconnect network, directory structure, and protocol of S2MP are discussed in detail."
