Study Dynamic Load Balancing Strategy in Computing Grid

Load balancing schedule strategy is very important for grid computing system.The strategy can hand out subtasks to each grid node well-balanced so this strategy plays a role of reducing cumulative computing time.This paper first studied general-purpose dynamic load balancing strategy;the model of information acquirement and task task allocation in grid based on globus;the method of getting grid nodes' parameters of hardware,software and file system.Then grid-specific dynamic load balancing algorithm was proposed and applied in a seismic wave field forward simulation experiment.The results show this algorithm takes full advantage of each grid node's resources and reduces computing time of compute-intensive tasks.
