Abstract :
Two rollback recovery schemes are proposed for tolerating transient and permanent faults, respectively. In both schemes a system state is saved in parallel with process execution periodically and automatically by dedicated hardware. The performance of proposed recovery schemes is studied. Closed-form expressions of the mean and variance of a task execution time are derived.<>
