Foil 69 Delta Comunication Network (cont'd)

From New CPS615 Foils-- B 28 August 95 CPS615 Basic Simulation Track for Computational Science -- Fall Semester 95. by Geoffrey C. Fox
System-Wide Communications Fabric
  • handles all inter-node communication
  • handles all I/O communication
Interconnect supports arbitrary expansion increments
Automatically routes messages without interrupting intermediate compute nodes
Nearly equal performance between any 2 nodes, independent of distance between them
Programmer can ignore details of how messages move along the interconnect network
Mesh Routing Chips have 5 bi-directional channels each
  • Mesh routing chip delivers messages from sending to receiving nodes
  • Developed at Caltech by Prof. Charles Seitz under DARPA sponsorship
Interconnect supports 28 MBytes/sec node-node bandwidth
Allows node fault isolation
