基于信誉度效益最优的网格调度算法研究

Research of Grid Dispatch Algorithm Based on Optimal Credit Benefit

基于经济模型的网格调度算法是目前网格环境中非常重要的算法,而信誉度是经济模型的一个概念。文中将信誉度问题引入到网格资源分配中,通过信誉度与效益相结合,提出了基于信誉度的网格资源分配算法。将信誉度融入到网格资源调度中,用户可以选择信誉度高的资源,提高了资源的信誉度,同时使得网格资源的质量有所提高。通过实验对算法进行了验证。实验结果表明,在费用和时间限制相同的情况下,该算法在使网格资源获得效益上优于时间最优化算法和代价最优化算法,并且提高了资源调度的效率。

The grid scheduling algorithm based on the economic model is very important in grid environment, and creditworthiness is a concept of economic model. Introduced creditworthiness into the grid resource allocation. Through combining creditworthiness with benefit, proposed the grid dispatch algorithm based on the optimal credit benefit. Will credit into grid resources scheduling, the user can choose high credibility of resources, improve the credibility of the resources of the grid resources, while making the quality improvement. And the experimental results show that in the same limit situation of expense and time, this algorithm is superior to time optimization algorithms and cost optimization algorithm in the efficiency of grid resources allocation, and improve the efficiency of the grid resources scheduling.
