  • The existing fault-tolerant scheduling algorithms are mainly based on primary/backup copies technology and the utilization of processor decreases greatly with the number of faults increases. In this paper, a real-time fault-tolerant scheduling algorithm is proposed to schedule periodic and aperiodic tasks jointly and tolerate multiple processor faults. The DS (Deferrable Server) algorithm is extended to the multiprocessors system, and several deferrable servers can be set to schedule aperiodic tasks. The faults can be tolerated by tasks rollback executing on the other processors. The experimental results demonstrate that this algorithm can guarantee all accepted tasks deadlines and decreases the number of required processor significantly.
