Cost-effective global fault-tolerant multiprocessors

Abstract

The global design approach we propose for fault-tolerant multiprocessors is cost-effective, while assuring full spare utilization during a proper reconfiguration process. Use of task reassignment during reconfiguration helps keep system costs effective and system size expandable easily. Our scheme is topology-independent; that is, any multiprocessor system can be applied. As compared with previous work, the proposed scheme can achieve higher or the same reliability at less extra hardware cost.<>
