Some Views on Building Computational Grids Infrastructure

This paper gives some opinions about grid bottleneck problem, and makes some suggestions about grid structure. It also introduces how to construct the global grid with sub grids, and to make use of the advantages of administrative hierarchy. The paper presents the conceptions of static resources, dynamic resources and the ways of scheduling resources. Also, the functions of resource marketplace are discussed. Finally, we describe the relationship, function and structural the principle of virtual organizations.
