Abstract

To solve the bottleneck problem of tasks that the interdependence between tasks fails to consider during the course of resource assignment and task scheduling based on the heuristics algorithm, A Grid Resource's Domain Split Assignment Method (GR-DSAM) is presented, which based on association rule model to group the sub-tasks. First, in order to enhance the subtasks' relationship of the same sub-task-group and strengthen the independency of the sub-task-groups, this method groups all sub-tasks, which have been syncopated from users' initialization tasks according to the interdependence of the sub-tasks. Secondly, the GR-DSAM takes the sub-task-group as one execution unit for reducing the unit communication, and improving the system's efficiency. At the same time, the GR-DSAM divides the Grid resources into dynamic regions according to the sub-task-group's resource demands. Simulation results show that the GR-DSAM is effective and efficient in solving the bottleneck problem of Grid resource assignment.
