摘要
(t, k)-diagnosis, which is a generalization of sequential diagnosis, requires at least k faulty processors identfied and replaced ( or repaired) in each iteration provided there are at most t faulty processors, where t = k. This paper suggests lower bounds on the degrees of (t, k)-diagnosability of multiprocessor systems under both the PMC and the MM* models. As a consequence, grids and tori of d dimensions are shown to be (O(Nd/d+ 1), Omega(d))- diagnosable and (O(Nd/d+ 1), Omega(2d))- diagnosable, respectively, where N is the number of processors.
