Reliability-Driven Tasks Scheduling for Real-Time System
Jun Zhang · 2003
In this paper, we describe a two-phase scheme to determine a scheduling of tasks with precedence constraints that employ a reliability measure as one of the objectives in a Real-Time and heterogeneous distributed system. The simulation results show that, for task graphs with precedence constraints in a heterogeneous Real-Time system, the method performs significantly better than the two algorithms presented that do not consider reliability cost. Furthermore, the results suggest that higher computational heterogeneity is conducive to improving the schedu-lability of the reliability cost-driven (RCD)algorithm, while the opposite is true for the two non-RCD algorithms.
