Abstract

Diagnosis by comparison is a realistic approach to the fault diagnosis of multiprocessor systems. The MM* model is a comparison-based model from which each processor has to test another two processors if they are adjacent to it. Sengupta and Dahbura presented a O(N5)-time diagnosis algorithm for general diagnosable systems under the MM* model, where N is the number of processors in the system. In this paper, by exploiting the cycle decomposition property, we present a O(N(log2N)2)-time diagnosis algorithm for a class of hypercube-like networks under the MM* model.
