网格中比较CPU计算能力的一种方法

Method of Comparing CPUs’Computational Ability in Grid Environment

采用计算量动态选择的算法,在网格节点上运行计算量适中的基准计算程序,获得CPU的MFLOPS值作为直接比较不同CPU计算能力的指标,为用户选择计算资源提供参考.实验证明,本方法能够稳定、灵敏地反映CPU的计算能力,使用它比较CPU的计算能力正确、有效.

By using the algorithm that can dynamically select computation cost and running a benchmark program with moderate computation cost in different grid nodes, the obtained MFLOPS value of CPU can be used as a parameter to compare different CPUs’ computational ability directly so that users can make choices among various computing resources by means of it. Our experiments have proved that this method can reflect a CPUs’ computational ability stably and sensitively and that using it to compare CPUs’ computational ability is proper and efficient.
