A multiprocessor digital data processing system comprises a plurality of processing cells arranged in a hierarchy of rings. The system selectively allocates storage and moves exclusive data copies from cell to cell in response to access requests generated by the cells. Routing elements are employed to selectively broadcast data access requests, updates and transfers on the rings.
