摘    要：提出了一种基于网格的现代设计框架(GMCD),并就其体系结构、关键技术如任务分解、协同环境等进行了讨论;通过定义一组任务关联性规则,对Globus工具包的资源描述语言进行扩展,以保证设计任务合理分解;为了有效解决协同环境中的冲突问题,提出了一种三级冲突消解策略;结合这些关键技术,利用Globus工具包、高级网络技术和网格中间件技术,GMCD具备了适应网格环境变化的“弹性”,克服了传统设计手段的封闭性、局限性和设计能力的不完备性,减少了设计资源的重复投入,缩短了产品研究和开发周期。

Abstract: This article introduces a GMCD framework based on grid, and discusses its architecture as well as key techniques such as job decomposing and collaborative environment. The resource description language of Globus toolkits was extended by defining a set of job relative rules to ensure the reasonable decomposition of design jobs. In order to resolve the conflicts in collaborative environment effectively, a three-level conflictresolving policy is brought forward. By combining these key techniques, and utilizing Globus toolkits, high level network technology and Grid middleware, GMCD has the flexibility of adapting to the dynamic environment of grid, overcomes the obturation, limitation and incompleteness of traditional designing methods, avoids the repeated investment of design resources, and shortens the developing period of products.
