<p>A parallel processor formed in each network node, comprising a network interface controller which controls the communication with the network. The interface controller comprises a message receiver which, in response to a message from another node, discriminates the receiving state of the message, necessity of returning an ACK message, etc.; an ACK generator which generates an ACK request based on prescribed information in the message and the receiving state of the message when the ACK message must be returned; and a message transmitter which generates and returns the ACK message upon receiving the ACK message request. When such a constitution is used, the network interface controller can return the ACK message and, as compared with the case where a processor returns the ACK message, not only the overhead can be reduced, but also the time required for returning the message can be shortened on the receiving side. Even when a message cannot be received normally, in addition, an ACK message can be returned.</p> |
