Research on grid resource scheduling for multi-QoS demands
基于多QoS需求驱动的网格资源调度研究

To solve the resource scheduling problem for multi-QoS demands, this paper adopted satisfaction function model and classical Min-Min algorithm. Firstly, it classified the numerous QoS parameters into two types which were performance QoS and trust QoS. Based on the priority, timeliness, precision of performance QoS and the security, reliability of trust QoS, it constructed five QoS satisfaction function models and formulated the overall satisfaction function model. Then it designed a multi-QoS constrained grid resource scheduling Q-Min-Min algorithm to compare with the classical Min-Min algorithm, in which the QSM replaced the ETC matrix. The simulation results show that Q-Min-Min algorithm gives more advantages over Min-Min algorithm in makespan and cost indexes, and prove the validity of grid resource scheduling based on multi-QoS demands.
