Base On Grid Computing Of Distributed Computing Related Works Method And Technology

With the increasing complexity of scientific calculation, the organization and implementation of large scientific project are facing cooperation and interaction among the human resources, heterogeneous computational resource and Multidimensional Information System.In this essay, we first researched on the grid computing technique which is popular in home and abroad. We analyzed and compared the grid computing technique and discussed Distributed Coherent computing technique. At the same time, according to the need of the research work, we studied the technical theory of Grid resource management and scheduling and summarized the current application area and development tendency of it.Secondly, based on the research work of Grid resource scheduling, we made in-depth study on grid job scheduling and co-allocation in the grid.Third, we emphasized the research work on resource cooperation scheduling in grid computing. According to the need of resource cooperation scheduling, we put forward a Distributed Coherent computing model based on Globus Toolkit software platform. After studying the grid job scheduling bidding mechanisms based on the economic mode, cost function model and related job finish time Prediction Model were introduced. Using cost function model to realize subjective initiative of recourse supply, which will make recourse scheduling rational and fast. And the distributed computing model also has the job scheduling Fault Tolerance.In the last part, we point out the deficiencies of out proposal in this paper, and forecast the development tendency of grid job scheduling.
