Abstract

We study the Distributed Memory Machine (DMM) with faults in memory. The DMM consists of n synchronized processors together with n memory units (MUs). A MU can be accessed by at most one processor at a time. The total number of memory faults is assumed to be at most a fixed fraction of the total number of words. We develop two fast randomized simulations of the PRAM on such a faulty DMM. A simulation consists of two phases: the preprocessing is followed by the simulation proper done in a step-by-step fashion. One simulation is of an n log n-processor PRAM and it operates with the optimal expected slowdown O(log n), the other is of a PRAM with n/log n processors and has the slowdown O(log log n).
