Using store-checkpoints (SCPs) and compare-
checkpoints (CCPs), we present an adaptive
checkpointing scheme that dynamically adjusts the
checkpointing interval on line in this paper. With additional
SCPs and CCPs, we can use both the comparison
and storage operations in an efficient way
and improve the performance of checkpointing
schemes. Further, we obtain methods to calculate the
optimal numbers of checkpoints by which minimize
the mean execution times. Simulation results show
that compared to previous methods, the proposed
approach significantly increases the likelihood of
timely task completion in the present of faults.
