Research of Scalability Model Based on Beowulf Cluster
Hou Xiu-jie · Computer Technology and Development · 2009
Scalability has become an important indicator to measure the match degree of parallel algorithms and parallel system.The iso ratio of parallel overhead to computation is reviewed in this paper,the merit and deficiencies of this metric are pointed out.Then in order to apply the distributed parallel computation environment based on Beowulf cluster it is improved,obtain the new extensible function which reflects the scalability of distributed parallel systems more directly and precisely when the size of machines and the scale of problems are extending in the environment of Beowulf cluster.Finally,the new metric is used to analyze and prove the scalability of parallel algorithms and Beowulf cluster.
