DESCRIPTION

opal-checkpoint can be invoked multiple, non-overlapping times. This allows the user to take involuntary checkpoints of a running sequential process. See opal_crs(7) for more information about the CRS framework and components. It is convenient to note that the user does not need to spectify the checkpointer to be used here, as that is determined completely by the running process being checkpointed.
