科学计算工具网格设计与实现

Design and implementation of science computational tool grid

为了整合科学计算资源并为用户提供一个简单的使用方式,在面向服务,着力于用户需求的开发原则下,进行了科学计算工具网格总体设计,包括功能目标、总体结构设计、模块间的相互作用.整合了科学计算软硬件资源,提供了对特定应用作业调度的支持,利用Portlet框架以及XML Schema等技术为网格用户访问底层科学计算资源提供了简单的网格服务访问方式.目前在合肥网格结点建设中完成了原型实现,证实了该工作的有效性.

The application requirements of science computation present strong demands of grid computing. Based on the principal of service oriented, focusing on user＇s needs, an architecture design and a prototype implementation of science computational tool grid in Hefei grid node construction were presented, including function goals, systematic structure design and interaction among modules. Computational resources were aggregated and support of specific application＇s job scheduling was provided. Based on Portlet framework and XML（extensible markup language） Schema technology, it also provides a simple way to access grid resources. The implementation in Hefei grid node construction confirmed the validity of the job.
