网格环境中的资源发现机制研究

Research on resource discovery mechanisms in grid

网格环境中高效的资源发现是直接关系网格性能的核心因素之一。现有资源发现机制都未考虑资源自身在资源发现过程中的主动作用,据此提出了一种资源主动声明机制。处于可用状态的资源,可以通过向潜在用户发送声明信息,声明其可用状态,主动供用户选择。并且介绍了该机制的关键技术、实现过程,指出了该机制在提高资源利用率,缩短资源发现时间,改善资源管理性能方面的优势。

Efficient resources discovery is a crucial problem for the performance of grid. The existing resource discovery mechanisms don＇t think of the activity of resources. A active declaration mechanism is proposed. The available resources can send declaration to their potential consumers, to declare their states. And then the key technology and working process are introduced and the result show this mechanism has a good capacity to increase the rate of resources utilization, decrease the time of resource discovery and improve the resources management performance.
