摘要
网格计算领域一个重要进展就是采用WEB服务计算模型作为其基本的体系结构,这就是开放网格服务体系结构(OGSA),它已经逐渐成为一种重要的分布式计算基础实施。对网格服务的使用者和提供者来说,一种全新的以网格服务集成和通过组装已有网格服务来创建新的增值服务的应用模式已经出现。网格服务的组合已经成为网格研究领域中一个重要课题。鉴于此,该文提出了一个OGSA框架下的网格服务组合语言GSCoL,讨论了GSCoL的设计,并介绍了在OGSA参考实现GT3核心的基础上完成的GSCoL的概念验证原型。
One of the most important achievements in Grid community is to adopt the web services model as its basic architecture.The result is called Open Grid Services Architecture(OGSA),which becomes a prominent paradigm for distribution computing.It is an emerging opportunity for both service providers and service consumers to create the value-added service by assembling new Grid service out of existing ones.This paper presents a grid service composition language named as GSCoL to address this issue within OGSA framework.This paper specifies the main ideals of the GSCoL design and an implementation of concept verification prototype of this language on the basis of Globus Toolkit3,the reference implementation of OGSA.
