The scheduling problem that maps independent tasks to heterogeneous resources in distributed computing systems is known as NP-complete[1]. GRID[2] is an example of distributed systems that consisted of heterogeneous resources. Many algorithms to solve this problem have been presented[1,3,4,5]. The scheduling algorithm can be classified into static scheduling algorithms and dynmic scheduling algorithms. A dynamic scheduling algorithm can be used when we can not predict the priority of tasks. Moreover, a dynamic scheduling algorithm can be divided into on-line mode algorithm and batch mode algorithm according to the scheduling time[1,6]. In this paper, we propose a new on-line mode scheduling algorithm. By extensive simulation, we can see that our scheduling algorithm outperforms previous scheduling algorithms.
