| Abstract: | The paper proposed a grid scheduling algorithm under the constraints of trust. Firstly, the algorithm combined direct experience and recommended experience to compute the trust of grid resources, secondly it ascertained the critical tasks according to execution time on candidate resource, and lastly it chose resources to meet integrated function of execution time and trust. A large number of experimental results show that the algorithm not only reduces the completion time, but also improves the success rate of scheduling. |
