QoS Matching Offset Algorithm Based on Trust-Driven for Computing Grid

Job schedule algorithm TDQMO based on trust-driven is presented for computing grid. In the paper, by introducing the conception of QoS matching offset between tasks and resources in Grid scheduling tasks are able to be allocated on demand. Meanwhile, we take into consideration the utility of QoS between tasks and resources in the scheduling. The simulation results show that the algorithm’s performance is better than TD Trust-Relation, TDMin-min in the aspects of trust utility, effective resource utility, load balance.
