Abstract : Message logging is a transparent solution to provide fault tolerance for message passing applications. O2P is an extremely optimistic message logging protocol that is proved to tolerate multiple failures. Extremely optimistic message logging aims at combining the advantages of optimistic and pessimistic message logging to be well-suited for large scale applications while minimizing the overhead on failure free execution. In this paper, we present the O2P protocol and prove that it can handle concurrent failures.
