Management method for a multiprocessor system

摘要

The number of instruction processors to be independently allocated to each supervisor is limited to a level at which the performance of the tightly coupled multiprocessor system is not deteriorated. A plurality of independent tightly coupled multiprocessor systems comprising these supervisors and a plurality of instruction processors are provided to improve their processing capacity. Since the existence of a plurality of supervisors complicates the management of these supervisors, a supervisor for a total managing service to which separate instruction processors are independently allocated is provided. This supervisor for a total managing service executes initialization and termination of the supervisors and monitoring of a fault, to thereby integrally manage the plurality of supervisors and the on-line control programs under their control. The supervisor manages the resources such as the main storage, the instruction processor and the input/output processors to utilize or manage the CPU's through the management terminals. The supervisor for total managing service, or operation supervisor, manages the status or faults of the supervisor and on-line control programs and provides change-over commands for the on-line control programs.
