A higher order estimate of the optimum checkpoint interval for restart dumps

This paper examines methods of approximating the optimum checkpoint restart strategy for minimizing application run time on a system exhibiting Poisson single component failures. Two different models will be developed and compared. We will begin with a simplified cost function that yields a first-order model. Then we will derive a more complete cost function and demonstrate a perturbation solution that provides accurate high order approximations to the optimum checkpoint interval.
