Abstract:
A parallel processing system comprising:a network; and a plurality of nodes which communicates asynchronously between said plurality of nodes through said network, and wherein each one of said plurality of nodes comprises a communication control unit connecting the one node to the network; and a plurality of CPUs, each of which CPUs acting as an issuing CPU generates and transmits an asynchronous communication request to the communication control unit of the one node, retransmits said asynchronous communication request in response to a non-acceptance reply, and executes a subsequent process in response to an acceptance reply, wherein, the communication control unit determines whether said asynchronous communication request, sent by an issuing CPU of the one node, is acceptable, returns said acceptance reply to said issuing CPU when said asynchronous communication request is acceptable, and returns said non-acceptance reply to said issuing CPU when said asynchronous communication request is not acceptable, and executes said asynchronous communication request.
