A Grid Resource Management Mechanism Based on Dynamic Region

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 sub-tasks´ 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.
