ABSTRACT:
Benes networks are very effective in providing inter-processor communication in SIMD parallel machines, provided the communication patterns are compile-time determinable. These networks are ill suited when communication patterns are dynamically varying because of the long set up time requirements. The present invention is a method for handling dynamically varying communication patterns efficiently by operating the Benes network in a time division multiplexed manner, wherein during a given transmission period, the middle stage switches of the Benes network are configured as a portion of the middle stage switches of a Clos network configured to route all signals in a single period.
