Abstract :
Performance of the wraparound network through trace-driven simulation is examined. This network has a processor attached to each node, but the links in the network are unidirectional, and the two ends of the network are joined together. Traces of three representative parallel engineering/scientific programs are used as input to the simulator, and the performance of this network is compared to that of an omega network under the same inputs. The wraparound network and the omega network are found to perform similarly, while the size and cost of the wraparound network are smaller than those of the omega
