Abstract

PURPOSE:To simplify the program processing in case of changing a system configuration, by giving a logical rank to plural common memories, and designating the logical rank when each processor accesses the common memory. CONSTITUTION:Plural common memories 1a, 1b are made double, plural processors 2a-2d are connected to the memories 1a, 1b by a common memory bus 3 and a rank designating line 4, and the same processing is shared in its load by each processor 2a-2d. To these memories 1a, 1b, logical ranks A, B are given, and the ranks A, B of the memories 1a, 1b are designated through the rank designating line 4 from each processor 2a-2d. Subsequently, the common memory operation is set so that the read and write operations can be executed, without giving statuses 1-4 of status No., and the program processing in case of changing a system configuration is simplified.
