Abstract: Complicated and dynamic environment of the grid requires urgently supporting of autonomic paradigim.The paper proposes a new architecture of grid with autonomic computing feature.Autonomic grid service layer，autonomic multi-agent collaboration layer and policy layer that can express user needs accomplish self-managing function of the grid.In order to well implement the autonomic cooperation of agents，the paper presents the algorithm of constructing similarity-association tree of multi-agent.Running of grid prototype system implemented in the simulation environment shows that grid system with above architecture has abilities of self-configuration，self-optimization，self-protection and self-healing.

Key words: autonomic computing, grid architecture, autonomic grid service, multi-agent, policy, similarity-association tree
