Abstract

A parallel algorithm to determine the switch settings for a Benes permutation network is developed. This algorithm can determine the switch settings for an N input/output Benes network in 0(log2N) time when a fully interconnected parallel computer with N processing elements is used. The algorithm runs in 0(N½) time on an N½× N½mesh-connected computer and 0(log
