Reliability of cluster-based multiprocessor systems

The reliability of a cluster-based multiprocessor system is analytically evaluated using modeling techniques. The results indicate that the cluster-based system has low reliability relative to the crossbar and multiple-bus systems. The weaknesses of the cluster-based system architecture, as far as reliability is concerned, are identified and a slight modification of the system architecture is proposed as a remedy. Using the same analytical modeling techniques, the reliability of the modified cluster-based systems's reliability is close to that of crossbar and multiple-bus systems.<
