In this paper, we propose an efficient scheduling algorithm for problems in which tasks with precedence constraints and communication delays have to be scheduled on an heterogeneous distributed system with one fault hypothesis. Our algorithm combines the DSSOPT algorithm and the eFRCD algorithm. To provide a fault-tolerant capability, we employ primary and backup copies. In this scheme, backup copies can overlap other backup copies, and backup copies are not established for tasks that have more than one primary copy. The result is a schedule in polynomial time that is optimal when there is no failure, and is a good resilient schedule in the case of one failure. © 2007 Springer.
