We investigate a unified approach for fault tolerance and dynamic power management in distributed real-time embedded systems. Coordinated checkpointing is used to achieve fault tolerance, and power management is carried out using dynamic voltage scaling. We present feasibility-of-scheduling tests for coordinated checkpointing schemes for a constant processor speed as well as for DVS-enabled processors that can operate at variable speeds. Simulation results based on the CORDS hardware/software… CONTINUE READING
