The Research And Design Of Large Scale Cluster Software Consistency Maintenance Technique

In recent years, large scale clusters are widely used in environment like high performance computation. But because large scale clusters are always consisted of lots of nodes with a complex architecture, the work management and maintenance on them always are inefficient and bad-automatic by this time. A consistency maintenance system specially designed for large scale cluster will be beneficial to large scale clusters'running and popularization.According to the research of cluster maintenance technology and related project models, to improve the performance of consistency maintenance, we get a complete set of solutions. The main tasks of this article include:1.By the research of existing technology, we design a high performance consistency maintenance system. A layered agent model is used in this system. The model split the tasks into smaller pieces and agents take these pieces. This makes the system scalable.2.This article pointed out a set of precept to control and harmonize the process of data transmission. Based on the precept, a virtual logical model was designed. This model makes the process of data transmission automatic and more efficient.3.Designed and realized a large scale cluster coherent maintenance system-Efficient Cluster Maintainer (ECM for short).
