Xiaoping Wang · Jisuanji gongcheng · 2010
This paper analyses the load imbalance problem and the QoS-based fault-tolerant schedule algorithm in grid resource schedule,and proposes a schedule algorithm based on the priority of a task-based parameters of QoS constrained schedule strategy. The method is based on using the generalized stochastic Petri net with inhibitor arc to establish the grid schedule 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.
