ABSTRACT:
A message receiving method communicates a message among a plurality of computers in a parallel computer system, shortens a delay time in storing a received message in a user area of a memory, and realizes overlap between receipt of a message and execution by a processor. Each computer in the parallel computer system comprises a message buffer for temporarily storing the received message and a message handler for receiving a receive-a-message request from a processor of a computer to which it belongs. If the receive-a-message request arrives before the arrival of the message, the message handler directly transmits the received message to a user area specified by the receive-a-message request. During the transmission period, the message handler prevents the processor from accessing a portion in the user area to which the message has not been transmitted yet.
