摘要
网格由分布在地理上的各种各样的计算机资源组成,用户在调用资源时,只会根据资源提供商所制定的条件来选择适合自己的资源,但是资源质量的优劣只有在至少用完一次后才可以得出结论。现今许多基于经济模型的资源调度策略只是在提高资源提供商的效益及资源调用时的负载平衡方面加以研究,而网格资源的质量并无过多深入的分析。文中提出的基于信誉度的网格资源调度算法,在用户与资源之间插入一个信誉度计算器,用户每调用一次便会对此资源进行一次信誉度评估。实验证明此算法不仅提高了资源提供商获得的效益,并且使得网格资源的质量得到进一步的优化。
The grid is composed by various computing resource which are geographical distribution,when the user sends out the resources request,resources is selected only according to the condition which is formulated by the resources provider,but the resources quality cannot be known unless they were used up at least once.Many economic models based on that resource scheduling strategy is to improve the benefit of resource providers and to adjust the load balancing of resources called,and the quality of grid resources is not too much in-depth analysis.Propose a grid scheduling of resources algorithm based on creditworthiness,this algorithm inserts a creditworthiness calculator between the user and the resources.Each time the user call for a resource,the algorithm will conduct a credibility assessment about the resource.Experiments show that the algorithm not only improves the resource provider to obtain benefits,but also makes the quality of grid resources can be further optimized.
