For real-time computing systems, fault-tolerance and energy efficiency are two primary design concerns. In this research work, we study the problem of aggressive deadline driven standby-sparing for hard real-time systems under energyawareness. The standby-sparing system adopts a primary processor and a spare processor to provide fault tolerance for both permanent and transient faults. In order to keep the energy consumption for such kind of systems under control, we explore aggressive deadline-driven scheduling schemes to minimize the overlapped concurrent executions of the workloads in the primary and the spare processors, enabling energy savings. Moreover, efficient online scheduling techniques are under development to boost the energy savings during run-time while preserving the system reliability.
