RSDictionary——一种用于分布式计算环境的全局名字空间
RSDictionary—A Global Namespace for Distributed Computing Environment
-
摘要: 资源管理是网格、P2P等分布式计算等领域的一个重要研究课题之一.提出了一种字典式的资源管理技术RSDictionary，能够打破网络拓扑结构的界限，将分散于网络结点上的各种资源依其名称组织起来，形成管理整个计算环境的全局名字空间；借助XML格式化消息传递机制，全局名字空间能够将资源加入和退出局限在尽量小的局部网络内，使得系统维护所需开销最小化，同时也简化了在整个名字空间中进行资源定位操作，系统管理和任务执行均可获得较高的效率.Abstract: Resource management plays a very important role in a grid or P2P computing environment. A global name space RSDictionary is presented to organize distributed resources based on the name instead of their hosting information such as the IP address and/or server name, etc. The RSDictionay defines a logical view and a physical view to manage the resources of such distributed environments to satisfy the efficiency requirements. The physical view organizes the resources into a static B-tree-like structure and mimics the organization of a dictionary, while the logical view is constructed at runtime according to the needs of a specific task. With the RSDictionary global name space, the computation resources can be solely deployed and referred by their name, and a local synchronization model is also introduced to minimize the maintenance costs.
