An information pool based grid architecture （IPBGA） was presented. Requests from resources for tasks and appeals from tasks for resources were upgraded as information services by using information pool protocol （IPP）. Thus

grid resource management and task scheduling were regarded as information matching by IPP which was adaptive to het- erogeneous

dynamic and distributed characteristic of grid system. Dividing virtual organization into information services layer and cooperation layer

it is helpful to build general view of information. Experiments and theory analysis show that information pool protocol of IPBGA is more efficient in searching and dealing with information while bandwidth cost and process cost are less.
