On the Communication Mechanismin RISE

We proposed a Real time Interactive Simulation Environment (RISE) . Communication mechanism was the key to the design of RISE but only outlined in Ref.. We now discuss in detail the communication mechanism in RISE. The design philosophy of the communication mechanism in RISE is quite distinctive in that hardware shares at least equal responsibility with software, whereas only software plays this role in existing products. Fig.2 shows schematically the system communication mechanism model which includes communication functions and intelligent routing units. The intelligent routing units undertake a considerable part of communication such as packing, routing, etc., thus relieving the software of a big percentage of its workload. We also take advantage of wormhole routing technique to reduce the delays in communication. Our design philosophy leads to the high efficiency of the implemented communication module of RISE: low overhead, high communication speed.
