The Research on Scheduling Algorithms Of Grid Spatial Database

摘要：

First, this paper describes several scheduling algorithms of grid spatial database, that is ,the random scheduling algorithm, queue length algorithm, visit cost algorithm and queue visit cost algorithm; Second, we make some simulation experiments on the operating capacity, operating time as well as processing unit utilization to these algorithms respectively with task capacity of 500,1000,2000,5000;at last, the results show that queue visit cost algorithm is the best one among them to deal with tasks under the grid spatial database environment, which can improve the efficiency of system operation, and let the system achieve the best operation status.
