摘要：A multi-processor system has a plurality of processing elements interconnectedby a network for transmitting data between the elements. Each of the elements has astatus table, indicating that element's view of the statuses of all the elements in thesystem, and a reliability map, containing a bit for each element in the system, along with

copies of the reliability maps of all the other elements in the system. Each element setsthe bits in its reliability map to indicate which of the other elements it is in regularcommunication with. Whenever an element's own reliability map changes, the elementsends a copy of that map to all the other elements. Whenever any bit changes in any ofthe reliability maps held by an element, that element uses the maps to perform a statusre-evaluation of all the elements, and updates its status table. This provides a consensusvoting mechanism which ensures that all elements arrive at the same view of the elementstatuses.
