<p>The apparatus, networks, systems and method of the present invention are predicated upon the following concept. …<??>A multiprocessor system intercouples the processors (14, 16, 18-23) with an active logic network (50a) having a plurality of priority determining nodes. Messages applied concurrently to the network (50a) in groups are sorted, using the data content of the messages, to a single or common priority message which is distributed to all the processors (14, 16, 18-23) with a predetermined total network delay time. Losing messages are again retired concurrently in groups at a later time. Message routing is determined by local acceptance or rejection of messages at the processors (14, 16, 18-23), based upon destination data in the messages. All messages occupy places in a coherent priority scheme and are transferred in contending groups with prioritisation on the network (50a). Using data, status, control and response messages, and different multiprocessor modes, the system is particularly suited for configuration in a relational data base machine having capability for maintaining an extended data base and handling complex queries.</p> |
