Data-Intensive Applications Management Framework with QoS Guarantee in Grid Environments
有服务质量保证的数据密集型网格应用管理研究

Effectively management of data-intensive applications in grid environments is challenging, due to a need to consider for both computational resources and data storage resources. This paper proposes a management framework for such applications with QoS Guarantee. This framework includes two parts, one is replica management based on availability of data, and the other is deadline-based job scheduling model. In the end, a simulation evaluation and two real applications evaluation over HUSTGrid are presented, the results of the evaluations show that this framework is suitable for data-intensive applications, and the performance of this scheduling method is better than the related methods.
