Abstract : Energy aware data centers are new demand of the high performance computing (HPC) industry. In recent years,increasing research efforts have also been devoted to the design of practical power saving techniques in HPC which is a integral part of content delivery networks (CDN)s. This paper gives survey of latest researches on power optimization and estimation. We firstly highlight the necessities of saving power i n HPC,followed by the identification of major power-saving strategies that have been widely exploited in the literature. Furthermore,We present high-level overview of the basic mechanisms to handle the power characteristics of H PC system. Then we review the power optimization research at various levels of HPC architecture. Based on this,discussion over the opportunities and problems present in the current techniques,We believe that this paper will help future researchers to explore more on this area. An d before conclusion,some ideas that are come across during writing this paper
