Abstract

The interconnection network is the communication backbone of a parallel processor system on which all remote data accesses occur and, thus, has a strong influence on the overall performance of the system. While the bandwidth delivered by conventional electronic-based networks has increased slowly in recent years, the bandwidth demanded by processors has increased at a much faster pace, soon causing the network to become a performance bottleneck. Optoelectronic-based networks can potentially provide much higher bandwidth capacity to mitigate this problem [1,2]. However, with the present growth rate of communication demand of distributed multiprocessor systems, even a high-bandwidth optoelectronic network (see Figure 1), could become oversaturated unless advanced routing techniques are incorporated in the interconnect architecture to efficiently utilize the bandwidth.
