Abstract
A data parallel processing system is equipped with two or more processing elements. On termination of data processing, each processing element informs an interconnection device of it. The interconnection device produces serial data on the basis of information indicating a progress of data processing by each of processing elements connected to it and information about the placement and configuration of the processing elements, then broadcasts the serial data to each of the processing elements. At this point, serial data of the shortest length is produced in such a way that processing elements not connected to the interconnection device or not in a ready state are omitted.
