基于校园网格系统的资源管理

Resource Management in the Campus Grid System

资源管理是整个校园网格系统中的关键和基础,通过对各种分布的、异构的资源的统一管理,以此实现对整个网格系统资源的一致访问并且使资源管理模块具有可扩展性。通过对资源的抽象、全局惟一资源ID号的分配和资源目录信息树的建立实现对网格资源的统一管理。孩子兄弟表示法的存储方式,大大节省了目录信息树的存储空间。网格系统中资源的注册和查询是按照IP是否位于同一网段内来实现的,在以后的任务执行中减少了主机之间的通信开销。

Resource management is a key and fundamental problem in the campus grid system. The resources in the grid are distributed and heterogeneous, by the uniform management, the model of the resource management can be extensible. This article implements the resource management by the abstraction of the resources,the allotment of overall situation unique resources number and the establishment of the directory information tree. The method of storage with child and parent saves the saving place of the directory information tree greatly. The register and search of the resources in the college grid system is realized according to the IP, so that the cost of communication between the hosts can be decreased when the task is performing.
