This paper discusses distributed periodic checkpointing for practical applications running with limited resources. We present a discrete time model evaluating the total expected overhead imposed on every event execution where the number of available checkpoints that each process can hold is finite and the rollback distance is bound to some finite interval. The recovery overhead for the checkpointing scheme is described by using a truncated geometric distribution as the rollback distance distribution. Although it is difficult to analytically derive the optimal checkpoint interval, which minimizes the total expected overhead, substituting other simple probabilistic distributions instead of the truncated geometric distribution enables us to do this explicitly. Numerical examples obtained through simulations are presented to show that we can achieve almost the minimized total overhead by using the new models and analyses. |
