Abstract

Recovery from transient processor failures can be achieved by using optimistic message logging and checkpointing. The faulty processors roll back, and some/all of the non-faulty processors also may have to roll back. This paper formulates the rollback problem as a closure problem. A centralized closure algorithm is presented together with two efficient distributed implementations. Several related problems are also considered and distributed algorithms are presented for solving them.
