针对网格环境中资源分布性、异构性等特点,提出了一种基于T.Cover最优投资决策模型的网格资源分配策略.采用GridSim进行模拟实验,并将该算法与随机算法进行了对比,结果表明该分配策略在任务完成时间及费用方面具有一定的优越性,能够提高资源分配效率,对动态、异构的网格环境具有较好的适应性,实现了网格资源的平衡分配.
Aimed at resources are distributed, heterogeneous characteristics in grid environment, a optimal investment decision model based on T. Cover is presented. Running the model onto the simulator GridSim and comparing it to random algorithm. The results imply that this distribution strategy achieves better performance in the time of completing gridlets and cost, improving the efficiency of resource allocation, it has good adaptability in the dynamic, heterogeneous grid environment, realizes the balancing distribution of grid resources.
