Efficient Techniques for Adaptive Independent Checkpointing in Distributed Systems

This work presents two novel algorithms to prevent rollback propagation for independent checkpointing: an efficient adaptive independent checkpointing algorithm and an optimized adaptive independent checkpointing algorithm. The last opportunity strategy that yields a better performance than the conservation strategy is also employed to prevent useless checkpoints for both causal rewinding paths and non-causal rewinding paths. The two methods proposed herein are domino effect-free and require only a limited amount of control information. They also take less unnecessary adaptive checkpoints than other algorithms. Furthermore, experimental results indicate that the checkpoint overhead of our techniques is lower than that of the coordinated checkpointing and domino effect-free algorithms for service-providing applications. key words: distributed systems, fault tolerance, checkpointing, failure recovery
