Abstract	We study fault-tolerant multiprocessor scheduling under the realistic assumption that the occurrence of faults cannot be predicted. The goal in these problems is to minimize the delay incurred by the jobs. Since this is an online problem we use competitive analysis to evaluate possible algorithms. For the problems of minimizing the makespan and minimizing the average completion time (for static release times), we give nonclairvoyant algorithms (both deterministic and randomized) that have provably asymptotically optimal competitive ratios. The main tool used by these algorithms to combat faults is redundancy. We also show that randomization has the same effect as redundancy.
