Study of a Grid User Whole Life Cycle Management Model Based on State Chart

This thesis took the user's state and activity of grid user management as the studying matter.First,this paper introduced the location and role of user's state and activity in the user management architecture,presented a kind of user state chart based on meta and sub state and gave the classification and de-finition of each metastate.The definition and elements of each substate attached to each type of metastate and their relations were studied.Based on the state de-finition,this paper studied and defined user's activity-transition action and gave the grid user's state transition chart.Finally,this paper introduced the application of this model in the portal of high performance computing environment.
