PURPOSE:To detect the down of a processor without subjecting heavy load to a CPU at the time of normal operation and without making a bus busy by providing the system with an auto-repute information control device. CONSTITUTION:Respective processors 11-14 are connected to the auto-repute information control device 2 and a common storage device 3, and when a fault is generated in a self-processor, the processor can execute automatic rerising on the basis of the auto-repute function. When auto-repute start information or auto-repute end information is sent from the processors 12-14, the device 2 sends the processor number and the information to the master processor 12. When the information is sent from the master processor 11, the information is sent to the master-substitutive processor 12. The processor 11 or 12 receiving the auto-repute start information starts time monitoring, and if receiving the auto-repute end information within a fixed time, regards the processor concerned as a downed processor and informs the processor number of the downed processor to all the other processors through inter-processor communication.
