Abstract:
As the energy problem of cloud data center is becoming more and more serious, the BoT ( Bag olTasks) seheduling algorithm considering only timespan can not adapt to the cloud computing environment. lnorder to guarantee users to perlom experienee, and also eleclively reduee the energy consumplion, this papeipresents a two-step energy-aware task scheduling algorithm, called DH-CRO algorihm. DH-CRO takingmakespan as the main optimization goals, meanwhile adjusts energy consumplion by DVFS technique. Experimental results verily DH-CRO algorithm is more efficient than other algorithms, such as GA, Min-Min, CROand so on. DH.CRO using in cloud environment can optimize the makespan to the maximum extent, and re.duce the total energy consumption at the same time.
