基于多服务质量属性联合效用函数的网格资源调度

Grid resource scheduling based on the multi-QoS attributes joint utility function

基于经济模型研究网格服务质量(QoS)控制的资源分配问题,给出了多QoS属性多任务的资源分配优化的效用模型.该效用模型描述了网格任务的动态需求和偏好,以效用最大化为目标计算了需要提供QoS的资源分配.设计了时间和预算限制条件下基于多QoS属性的联合效用函数调度算法,并与其他经济的和非经济的算法进行比较,验证了该算法的有效性.

The economic model was applied to solve the QoS （quality of service） guarantees problem, and a utility model expressed in multi-QoS attributes was presented, which can be used to dynamically allocate resource in the Grid. A multi-QoS attributes-based joint utility function scheduling （JUFS） algorithm under the deadline and budget constrain was proposed. The performance of the algorithm was evaluated through a series of simulations. Comparisons with other economic and non-economic algorithms show that the performance of the JUFS algorithm matches well with the service on demand in the Grid.
