Abstract: In a multiprocessor computer communication among the components may be based either on a simple router, which delivers messages point-to-point like a mail service, or on a more elaborate combining network that, in return for a greater investment in hardware, can combine messages to the same address prior to delivery. This paper describes a mechanism for recirculating messages in a simple router so that the added functionality of a combining network, for arbitrary access patterns, can be achieved by it with provable efficiency. The method brings together the messages with the same destination address in more than one stage, and at a set of components that is determined by a hash function and decreases in number at each stage.
