Abstract: Trust mechanism and computation performance are more important in a realistic grid resource management.Based on the grid service model and utilization function,grid task scheduling problem of trust and computation balance is proposed.Balance factor is added to utilization function of grid task scheduling.BF-ACA(Balance Factor Ant Colony Algorithm) is presented.Value of balance factor is decided by experiments.BF-ACA is evaluated with large scale simulation.Simulation result demonstrates BF-ACA performance better than BF-Min-min and BF-Sufferage on make-span and service ratio.

摘要: 针对当前网格资源管理中信任机制与计算性能结合的要求,基于网格服务模型与效益函数,提出信任机制与计算性能平衡的网格任务调度问题。在网格任务调度的效益函数中引入平衡因子,提出平衡因子蚁群算法,通过实验确定平衡因子值。对网格任务调度的平衡因子蚁群算法进行大规模仿真实验,有力地证明了平衡因子蚁群算法优于平衡因子极小-极小算法和平衡因子忍耐度算法,在最短完成时间和服务率方面具有较好的综合性能。
