基于Globus Toolkit的网格服务实现

在下一个十年里，许多业务将通过使用支持网格计算架构的Web服务在因特网上进行集成而实现彻底的转变。本文采用Globus提出的开放网格服务体系结构（OCSA）中的接口定义来实现网格服务，以数字化虚拟中国人（VCH）重建中的关键算法为例，简单的介绍了在Globus Toolkit3下服务封装的过程。用户使用网格门户页面或应用程序，对封装后的算法资源、计算资源进行访问，避免复杂算法的重复开发，打破了计算能力大小的限制、地理位置的限制。

Grid Service Based on Globus Toolkit

During the next decade,a lot of operations will be thoroughly changed via integrating the Web service which supports the fabric of grid computing service on internet.Taking the reconstruction of Visible Chinese Human(VCH) as an example,some conception and the processes of grid service development based on Globus Toolkit are introduced in detail in this paper.Users can access the algorithmic resources,computational resources via Grid Portal or application.
