Abstract

PURPOSE:To reduce concurrence of a common memory, and to decrease occurrence of overhead, by using the common memory device in common by each computer system, and also using other computer in common to an individual main storage device of each computer. CONSTITUTION:A common memory device SM10 is used in common by plural computer systems 21a, 21b, and coupling modules 22a, 22b for connecting each system 21a, 21b to each other are provided and are connected by an interface signal line group 23. By these modules 22a, 22b, whether a memory address generated in a high rank computer system belonging to said modules 22a, 22b is an address to the system to be connected 21a or 21b, or not is detected. Subsequently, in accordance with a result of detection of the address, an access request is outputted to the other system 21b or 21a, and also when an access request approval has been sent back from the other system, individual main storage devices 15a, 15b are accessed under the control of CPUs 13a, 13b, and concurrence of the memory device SM is reduced.
