Abstract

In arrays of processors, especially linear arrays, it is important to be able to communicate to adjacent neighbors (en masse). That is, each element of the array can communicate with its neighbor on the left simultaneously. In addition, the array processor is provided with the ability for selected elements of the array, picket processing elements, to simultaneously communicate with other elements that are further away in one dimension than the nearest neighbor in one transfer cycle. This is accomplished by causing intermediate elements to become transparent in the communication paths, thus allowing data to 'slide' through intermediate nodes to the destination node. This system can be used in the implementation of fault tolerance in the array of elements.
