Abstract

PURPOSE: To omit the hardware exclusive for communication between processors by securing a rational and independent use for the processor proper memory unit and the shared memory unit, and thus to ensure the recomposition of the system with enhanced maintenance and expansion performance.
CONSTITUTION: In the composite computer system of the load sharing type comprising two units of processors 1 and 2, processor 1 and 2 are connected to shared memory unit 3 between processors. And the access can be given to unit 3 from either processor 1 or 2. Shared resources control unit 7 and 9 (for external memory unit, printer, etc.) selects the allotment of shared resources group 8 and 10 to either of the processors. Specification part 12 and 13 of common information form C store the definite procedure and process result for the job process to be stored in unit 3 in the form of a table. At the same time, process program 16 and 18 of information form I-series and II-series carry out the actual process based on the procedure shown in part 12 and 13. The programs are exactly identical on both processors 1 and 2.
