ABSTRACT
<p><b>Abstract</b>—Checkpointing reduces loss of computation in the presence of failures. Two metrics characterize a checkpointing scheme: checkpoint <it>overhead</it> and checkpoint <it>latency</it>. This paper shows that a large increase in latency is acceptable if it is accompanied by a relatively small reduction in overhead. Also, for equidistant checkpoints, optimal checkpoint interval is shown to be typically independent of checkpoint latency.</p>
INDEX TERMS
Checkpointing and rollback, checkpoint latency, checkpoint overhead, performance analysis.
