Using early termination support

Early termination support allows you to terminate an application job at a scheduled time of day (after a completed checkpoint), on command after a checkpoint, or on command immediately after the next call. Termination after a checkpoint requires no backout because the checkpoint signifies that the changes are committed. Immediate termination requires backout of uncommitted changes. In both cases, all restart information is left intact and ready for restarting the job at the last completed checkpoint.
