A Hybrid Message Logging-CIC Protocol for Constrained Checkpointability

Communication Induced Checkpointing protocols usually make the assumption that any process can be checkpointed at any time. We propose an alternative approach which releases the constraint of always checkpointable processes, without delaying any message reception nor altering message ordering enforced by the communication layer or by the application. This protocol has been implemented within ProActive, an open source Java middleware for asynchronous and distributed objects implementing the ASP (Asynchronous Sequential Processes) model.
