Temporal Violation Handling Point Selection
In scientific cloud workflow systems, temporal violation handling points are those workflow activity points where temporal violation handling strategies are triggered to tackle detected temporal violations. The existing work on temporal verification adopts the philosophy of temporal violation handling required whenever a temporal violation is detected. Therefore, a checkpoint is regarded the same as a temporal violation handling point. However, the probability of self-recovery which utilises the time redundancy of subsequent workflow activities to automatically compensate for the time deficit is ignored and hence would impose a high-temporal violation handling cost. To address such a problem, this ...
