摘    要:将工作流技术应用到网格领域中。作为复杂网格应用的一种编程模式是出现网格工作流这一概念的目的。但网格动态、异构、分布的运行环境给传统工作流技术的应用带来了许多新的挑战。其中,主要包括活动的协调、数据流管理、服务的动态绑定、事务性与异常处理、流程的验证和优化以及流程运行的监测等方面的内容,针对这些问题,文章从工作流生命周期的角度出发,并结合具体相关的研究项目作出较为深入的分析,并指出了可行的解决方向。

关 键 词:网格工作流  动态绑定  服务协调  语义

Abstract:In order to run complex grid application automatically, the grid workflow technology is referred to. But when it comes to apply the traditional workflow technology to the grid, the underlying environment, which are dynamic, heterogeneity and distributed, will bring lots of new challenges. Most of all, the coordination of activity, the management of dataflow, the dynamic binding of services, transaction and exception handling, the verification and optimization of workflow, and the monitor of worktlow running consist of the main parts. As for those challenges, the article based on the analyzing many related research projects concludes the essences of those problems and gives some corresponding solutions in the views of the workflow lifecycle lifetime.
Keywords:Gird worktlow  Dynamic binding  Service coordination  Semantic
