Abstract: Grid computing is a new distributed technology, which connects distributed and heterogeneons resources with high-speed network integrating a super computer of processing capacity? The paper not only explain significanee and architecture of grid computing, but also expand on several kernel technology such as OGS1, resource management, task management, task scheduling , high rate communication, security, ect. Aiming at the particularity of the grid computing environmerits, We designed a mechanism similar to technology of search engine with which we may registry, discovery, locate resources in Grid. The whole model of resource management is built by connecting task manager in local resource management system and others with P2P model. Task may migrate among task managers in order to balanee load? Task users summit may be executed in relatively tight resource sets, which will not only decrease the total comm uni cation overheads of the whole task but also enhance the performance of system? Then , we analyze the new Standardof the Grid: OGSA. In the endof thisarticle 、 we design the keypartsof Grid computing in enterprises application: thefunctionof dispatch and thefindfor the Grid service.

Key words: grid computing technology； computing knot； supercomputer； supe r processing capacity； resource management OGSA , Gridservice , Enterprise Applicati on
