Abstract

PURPOSE:To improve the efficiency of interruption processing by setting an information storing means, an interruption deciding means and a means which carries out the interruption based on the decision of said deciding means in response to plural computers forming a multi-computer system and performing the interruption based on interruption information. CONSTITUTION:The computers 241A-241D of the same constitution are connected to the ports 210A-210D formed within a common memory adapter 200 which controls the interruptions among those computers 241A-241D. The outputs of the ports 210A-210D are stored in a common memory 231 set outside the adapter 200 via an incorporated control part 221. In such constitution of an interruption control system, the interruption information consisting of 8-bit data is stored in a register 211A of the corresponding port 210A when an interruption is given from the computer 241A to another computer. The part 221 reads out the interruption information and a request given to the computer 241B is decided by a fact that a 1st bit is equal to '1' with 6th and 7th bits equal to '01' respectively. Such operations are repeated so that the interruptions are carried out among those computers with each other.
