Abstract :
The Scalable Coherent Interface (SCI) standard defines a new generation of interconnection that spans the full range from supercomputer memory `bus´ to campus-wide network. SCI provides bus-like services and a shared-memory software model while using an underlying packet protocol on many independent communication links. Initially these links are 1 GByte/s (wires) and 1 GBit/s (fiber), but the protocol scales well to future faster or lower-cost technologies. The interconnect may use switches, meshes, and rings. The SCI distributed-shared-memory model is simple and versatile, enabling a smooth integration of highly parallel multiprocessors, workstations, personal computers, input/output, networking, and data acquisition
