Relentless technology scaling not only dramatically increases the energy consumption of modern processors, it also makes processors less reliable. In this paper, we study the energy minimization problem for real-time applications on multi-processor platforms while tolerating K transient faults using checkpointing. We first introduce an efficient method to determine the checkpointing scheme that minimizes the worstcase response time for a task set that shares the reserved recoveries on a single
