【摘要】 在多个计算机机群构成的网格环境下,为了提高异构资源的利用率,提出了一个数据负载均衡模型。根据查询节点的计算能力、存储能力、通信能力,研究了查询节点的性能模型。利用数据饱和度、数据负载矩阵、数据迁移技术描述了系统的数据负载均衡机制。试验结果表明:该模型适合海量数据的查询。更多还原

【Abstract】 To improve the utilization efficiency of heterogeneous resources in Multi-Cluster Grid (MCG) composed of many computer clusters, a data load balance model was proposed. According to computation power, storage power, and communication power of query node, the performance model of query node was studied. By using data saturation, matrix of data load balance and data migration technology, system’s data load balance mechanism was described. Experiment results show:The model can be fit for querying massive data.更多还原
