Abstract:
There are many replicas in data grid,In order to efficiently and fastly make sure the most effective replica, we use simulated annealing algorithm to fulfil the requirement of the running job and minimize the cost of the job and improve the overall profit.Through using OptorSim simulator,test results prove the effectivity of the policy.[著者文摘]
