Research On Constructing Of University Computing Grid

The variety of computing resources in colleges and universities can't be fully utilized because of the heterogenity and distribution of computing resources, which exacerbate the situation of campus computing resources can not meet the teaching, scientific research and other areas of the urgent need of high-performance computing to a large extent. Fortunately, grid technology provides an opportunity to solve this problem. Thus, the research on the construction of campus computing grid platform, which focus on how to use grid technology to efficiently organize various computing resources on the campus network, shield these resources' internal heterogeneity and dynamic characteristic, and form a campus computing grid platform with the characteristics of fully-sharing, teamwork, relatively transparent to the users, is a very meaningful research subject.At the beginning of the paper, we made an in-depth research about grid technology, especially on the grid architecture.Further, we also analyzed the demand of campus computing grid platform and the characteristics of campus computing resources.Then, we designed a campus computing platform model, and proposed its specific implementation solution. At the same time, we paid more attention to the research on grid task scheduling problem, analyzed some of the existing grid task scheduling algorithm, and proposed a grid task scheduling algorithm based on users' demand. This algorithm add users' demand to the process of task scheduling as an important factor so that task schduling can better meet users' needs. Simulation experimental results show that the algorithm has good practicality in respect of scheduling a large number of independent grid tasks.Finally, we used Gt4, Condor-G, Java Cog Kit and other software tools to design, implement a small campus computing grid experimental platform on the basis of previous theoretical research. Authorized users can submit jobs through platform's grid protal, and monitor the implementation of their jobs, as well as download the results of the implementation of their jobs.
