In this paper, we design and analyze strategies to replicate the execution of an application on two different platformssubject to failures, using checkpointing on a shared stable storage. We derive the optimal pattern size~$W$for a periodic checkpointing strategy where both platforms concurrently try and execute $W$ units of work before checkpointing. The first platform that completes its pattern takes a checkpoint,and the other platform interrupts its execution to synchronize from that checkpoint.We compare this strategy to a simpler on-failure checkpointing strategy, where a checkpoint is taken by one platformonly whenever the other platform encounters a failure. We use first or second-order approximations to computeoverheads and optimal ...
