ABSTRACT:
A system applicable to a multiprocessor system for processing communications among central processing units (CPUs) in which, when one of the CPUs has sent process requests to a plurality of the other CPUs at the same time, end-of-process requests appearing asynchronously to each other are processed. If the CPUs to which the requests are meant for have ended processing normally, ending of all the kinds of processing can be completed within a short period of time and without restoring to complicated firmware processing. Even if the end condition at any CPU is abnormal, the firmware processing is simplified because the end reports are selectively returned based on a predetermined priority order.
