A GSPN-based Grid Resource Schedule Algorithm

The paper analyses the load imbalance problem and the QoS-based fault-tolerant scheduling algorithm in Grid Resource Scheduling, and proposes a new scheduling algorithm based on the priority of a task-based parameters of Qos constrained scheduling strategy. The method is based on using the generalized stochastic Petri nets with inhibitor arc to establish the grid scheduling model and improve the Min-Min algorithm. Experimental results show that the algorithm can decrease the overall cost of time and cost, when the Grid Resource Schedule runs an urgent task.
