System having fixedly priorized and grouped by positions I/O lines for interconnecting router elements in plurality of stages within parrallel computer

摘要

A network and method for interconnecting a plurality of router elements in a parallel computer. The network forms a routing system for routing data from source processing elements to destination processing elements. The input lines and output lines of each router chip are prioritized. Higher priority output lines from a given output group of a first routing element are connected to low priority input lines of a second routing element and lower priority output lines from the output group of the first rotating element are connected to higher priority input lines of the second routing element.
