【摘要】 <正>1引言随着网格技术的飞速发展,网格在越来越多的领域得到应用。为了克服这些应用中的人物关系、时序、空间以及权限等资源方面的约束条件所带来的工作效率低下问题,一些网格项目开始引进工作流技术来管理网格应用。例如美国能源部的GridAnt、NASA AMES研究中心的GridFlow、英国的GeneGrid等都采用了网格工作流技术。更多还原

【Abstract】 With the development of Grid technology,Grid Workflow is being applied to more and more area.However, the Grid Workflow is different with the traditional one:it will be managed by both the webservice ower and the workflow manager,as well as the dynamic of roles in the workflow.In order to solve these problem,we propose a Norm Method for role assignment in grid workflow.We treat the role and the entity separately to satisfy both sides of managers.What’more,according to the collaboration and relationship between the roles in grid workflow, we set a session of rules to make sure that roles will be assigned dynamicly and properly when the workflow is running. In the end,we will give an experiment on a data sorting workflow to show the benefit the Norm Method brings to us.更多还原
