一种基于灰色聚类的仿真网格系统性能评估方法

Study on Performance Assessmenting for Simulation Grid System Based on Grey Cluster

从仿真网格中节点的整体性能角度出发,针对如何确定包括任务量和通信量的负载问题,通过对底层网格物理资源和仿真联邦应用的相关性能参数进行分析,提出了灰色聚类的动态性能评估方法,建立了影响仿真网格系统性能的负载指标模型。该方法不仅可以避免以往评估算法的片面性,而且描述出了影响性能各因素间关系的强弱、大小和次序,达到了以网格动态性为中心的对系统进行评估的目的。

From the overall performance of simulation grid system,aiming at how to determine balance load including mission and traffic,according to analysis relevant performance parameters which related to the bottom of the grid physical resources and the federate application,the performance assessment methods with simulation grid system based on grey cluster were provided,which not only prevented one-sided assessment of the ancient algorithm,but also described the factors that affected the performance between strong and weak,size and order.Finally,the aim of dynamic assessment was achieved,and the performance assessment methods with simulation grid system based on grey cluster were provided.
