A Distributed Functional Diagnostic System for Multi-Computer Systems

A distributed self-testing method is designed for multi-computer systems of arbitrary mutual test graph. The method is helpful in detecting and identifying the location and type (defects, program failure, and faults) of faults in machines in the course of tests and hazardous faults in the course of exchange of local test syndromes between computers. The method is based on an s-nonfailure information matching algorithm for detecting and identifying faults in information exchange. The fault detection and identification mechanisms form a continuous functional diagnostic process.
