Efficient fault tolerance: an approach to deal with transient faults in multiprocessor architectures

Proceedings of 1994 International Conference on Parallel and Distributed Systems, 2002
Dynamic error processing approaches are an important mechanism to increase the reliability in a multiprocessor system, while making efficient use of the available resources. To this end, dynamic error processing must be integrated with a fault treatment approach aiming at optimising resource utilisation.
