In this work, we have addressed the complex problem of recovery for cluster computing environment. The proposed approach handles both inter cluster orphan and lost messages unlike the existing works in this area. We first propose an algorithm to determine a recovery line so that there does not exist any inter cluster orphan message between any pair of the cluster level check points belonging to the recovery line. The main feature of the proposed algorithm is that it can be executed simultaneously by all clusters in the cluster federation. Next we apply the sender-based message logging idea to effectively handle all inter cluster lost messages to ensure correctness of computation.
