 \section{Conclusion}
 \label{sec.concl}
 In this paper, we have presented a new online heterogeneous scaling algorithm
 that selects the best possible vector of frequency scaling factors. This vector 
-gives the maximum distance (optimal tradeoff) between the normalized energy and

 cluster. The proposed method evaluated on Simgrid/SMPI  simulator to built a heterogeneous 
 platform to executes NAS parallel benchmarks. The results of the experiments showed the ability of
