Abstract:
A priority calculating method was proposed, in which the grid workflow applications' priority vector was calculated by the users' identity, credit, urgency and dependency of grid applications in the workflow. The full priority scheduling algorithm generates the scheduling list according to the priority vectors, and only the application which has the highest priority can be submitted while the non-absolute priority scheduling algorithm schedules several independent grid applications so as to compensate the parallelism problem of the full priority scheduling algorithm. Experiments show that, when the grid has fewer available resources or the performance discrepancy of the resources is much higher, the full priority scheduling algorithm ensures the workflow applications that have high priority to be scheduled firstly; and when the grid contains more resources that have the same performance, the non-absolute priority scheduling algorithm avoids largely increasing of the workflow's makespan caused by resources waste.
