Abstract

In a multiprocessor system interconnected by a bus structure that provides communication and information transfers between the processor modules of the system, each processor broadcasts a central message to all the other processors of the system on a periodic basis. A processor module not receiving the control message from a sending processor module will assume the sending processor module has failed, and operate to take over the task of the failed processor module.
