Research On Constructing And Management Of University Computing Grid

The development and wider application of grid makes kinds of computing resources utilized in a deep degree. Considering status quo of computing resources in ChengDu University of Technology and the urgent needs of high-performance computing on school research, teaching in this campus, we put forward the demand of building university computing grid. In this paper, the architecture of university computing grid based on globus middleware is designed and implemented through the research on the existing university grid model and analysis of the characteristices of CDUT's resources.University computing grid in the design and realization of the architecture, not only makes campus computing resources are fully utilized, makes user group who use expensive resources which can not be replicated expanded, but also to eliminiate information and resources isolated island and to provide users with a safe, reliable, extensible web application environment. Any user through the identification can access the Internet at any one computer can submit their serial or parallel jobs through our university computing grid application platform. Through job monitoring module and resource management and discovery module, grid user can inspect and manage their jobs duly.To achieve both effective integration of resources and the safe use, we designed university computing grid into three-tier model, resource layer, grid services layer and user portal layer. This paper uses SGE to integrate resources, designs job scheduler to implement grid services layer, use Jsp/Servelt to achieve user portal. We give the university grid-building programme and through the use of example given a grid envirionment to achieve.
