网格计算资源管理中的信誉度模型

网格资源管理作为网格研究的核心内容,受到研究人员的高度关注。目前已经提出的诸多管理模型中,基于计算经济的模型被人们普遍看好。文中针对计算经济模型,提出了资源信誉度、资源提供者信誉度、资源消费者信誉度的概念。在此基础上,深入研究了信誉度评价的评价模型和算法以及信誉度评价实现中的一些处理策略。对信誉度评价所需的资源使用记录进行了定义,根据评价需要对现有RUR进行了扩展。最后通过仿真实验对信誉度评价算法进行验证,得到了相应的实验结果和结论。

Credit model of Grid resource management

Resource management is the central part of Grid computing system and the model is a prime concern. A lot of models have been brought forward by researchers and the most highlight is the computational economy model. In this paper, a credit model in which the resource credit, GSP credit and GSC credit model were defined was presented. In contrast to traditional resource management, the credit is public in Grid-wide according to the need and Integration into resource allocation algorithm. Then the implementation of the model was proposed and the credit algorithms, including the problems of Extended Resource Usage Record(ERUR) were designed. At last, some emulation experiments were offered to show that the credit model was efficient and valuable within Grid computing economy environments.
