Abstract
The present invention is directed to providing an interprocessor communication system capable of obviating degradation of the performance in an interprocessor communication caused by the processing to avoid a page fault. In this system, a source processor transmits a check packet directly after successive data is transmitted by the interprocessor communication, to confirm whether or not a page fault takes place on the receiver side. The source processor carries out no processing in the case that no page fault takes place, and, in the case that a page fault takes place, the data in the page-faulty page is retransmitted. The destination processor stores the logical page numbers of the page-faulty pages in the main memory to utilize the data retransmission. Furthermore, the destination processor confirms whether or not the page faults occur in the identical page and if that is the case, no interrupt is raised so as to avoid too frequent interrupts.
