Deadlines permit to model the urgency of
a task by specifying a maximum processing time. In GXflow, the deadlines of the
tasks under execution are monitored using several procedures:
WFDeadlineChecker. This procedure
controls deadlines a single time, that is, verifies the occurrence of deadlines
at the time the procedure is executed. WFDeadlineScheduler. This procedure
permits to obtain a real monitoring of deadlines, through permanent automated
control. This procedure receives as a parameter the time interval (in seconds)
that will elapse between the end of an execution and the start of the next. In
each execution the WFDeadlineChecker procedure is called.
External Scheduling Utility. For example,
the System Scheduler. For more information go to:
