Method of checkpointing parallel processes in execution within plurality of process domains

摘要

An embodiment of a method of checkpointing parallel processes in execution within a plurality of process domains begins with a step of setting communication rules to stop communication between the process domains. Each process domain comprises an execution environment at a user level for at least one of the parallel processes. The method continues with a step of checkpointing each process domain and any in-transit messages. The method concludes with a step of resetting the communication rules to allow the communication between the process domains.
