Abstract
A parallel processing system includes a network and a plurality of nodes which communicates asynchronously between the plurality of nodes through the network. Each of the plurality of nodes may include a plurality of CPUs and a communication control unit. Each of the plurality of CPUs as an issuing CPU generates and transmits an asynchronous communication request, retransmits the asynchronous communication request in response to a non-acceptance reply, and executes a subsequent process in response to an acceptance replay. The communication control unit determines whether the asynchronous communication request is acceptable, returns the acceptance reply to the issuing CPU when the asynchronous communication request is acceptable, and the non-acceptance reply to the issuing CPU when the asynchronous communication request is not acceptable, and executes the asynchronous communication request.
