Abstract: This paper analyzes the features of a grid system. According to the requirements of the grid system , it puts forward the architecture of the grid supporting middleware-grid operating system. The architecture consists of the kernel layer, constitution module layer and the aggregation module layer. According to the characteristics of the grid computing and services, it studies and analyzes the module and services that the grid OS should provide, then takes the Globus Toolkit2.0 as an example, analyzes and explains its function and shortcoming. Finally it explains the layer in which each module should be and introduces its latest advance.
