Hierarchical Grid Load Balancing Scheduling Algorithm Based On Statistics Thinking

As grid technologies evolve quickly on Internet,load balance research and development face new opportunities and challenges.These new technologies,ideas and approaches provide a new environment for researching and developing load-balancing system.Aiming at the distributed layered task scheduling model described in this paper,By researching this scheduling model,a computational resource selection algorithm based on double goals measurement function was proposed. The algorithm made a detail to elaborate This paper explained the functions and the relationships between the different parts of the model and give the algorithm of the mode1.The paper uses GridSim simulation tool to validated this model, Simulation results show that the proposed algorithm performs better than other scheduling algorithm in heterogeneous grid.
