| Abstract: | Aiming at cluster system,which has feature of without key node,high availability,better loading balance and rapid response time,the prevalent process migration algorithms have shortcoming of low migration speed and residual dependency.Regarding these problems,an improved preemptive process migration algorithm,which combines the merit of demand-page and pre-copy algorithm,is presented based on analysis of current process migration algorithm.According to experimental results,the improved migration algorithm can effectively improve the speed of process migration. |
