Grid scheduling strategies of trust mechanism and computation performance
Ming He · Computer Engineering and Applications Journal · 2010
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.
