Abstract

A digital data processing system and method with shared, distributed memory transfers data between corresponding data sets within memory. The digital data processing system includes a plurality of processing cells interconnected by a hierarchical network, at least some of the processing cells including a processor and a memory. Each memory provides storage space which is arranged in sets, with each set being capable of holding a plurality of data pages. At least one of the processing cells, as a first processing cell, includes a page distributor for determining when at least a first set in the associated memory has reached a predetermined storage commitment condition (for example, a filled condition). Under such a condition, the page distributor invokes a page-transfer element that selects a candidate processing cell from among the other processing cells and transfers one or more pages from the first set to a corresponding set in the candidate processing cell.
