Excessive power consumption emerged as a major obstacle to achieving exascale performance in next-generation supercomputers, creating a need to explore new ways to reduce those requirements. In this study, we present a comprehensive empirical investigation of a power advantage anticipated in the mergesort method based on identifying a feature expected to be physically power efficient. We use a highperformance quicksort as a realistic baseline to compare. Results show a generic mergosort to have a distinct advantage over an optimized quicksort lending support to our expectation. They also help develop some insights toward power efficiency gains likely meaningful in a future exascale context where trading some of the abundant performance for much needed power savings in a ubiquitous computation may prove interesting.

Power and energy efficiency are among the most crucial requirements in high-performance and other computing platforms. In this work, extensive experimental methods and procedures were used to assess the power and energy efficiency of fundamental hardware building blocks inside a typical high-performance CPU, focusing on the dynamic branch predictor (DBP). The investigation relied on the Running Average Power Limit (RAPL) interface from Intel, a software tool for credibly reporting the power and energy based on instrumentation inside the CPU. We used well-known microbenchmarks under various run conditions to explore potential pitfalls and to develop precautions to raise the precision of the measurements obtained from RAPL for more reliable power estimation. The authors discuss the factors that affect the measurements and share the difficulties encountered and the lessons learned.

“…When the research objects of energy efficiency are different, the calculation methods of energy efficiency are generally different. Energy efficiency refers to the use of relatively less energy while maintaining the same service or efficient output [9][10]. The results obtained by using different definitions and indicators are often quite different, which makes it difficult to judge the current level of energy efficiency in the region.…”

With the continuous increase of energy demand, the use of energy has caused many environmental problems, and the energy crisis has gradually attracted people's attention. By understanding energy efficiency, it provides good policy suggestions for improving my country's energy efficiency. The purpose of this paper is to use the Malmquist index model to analyze the energy efficiency evaluation model. In the experiment, the correlation matrix data of the original variables in the energy efficiency evaluation model, the standard values of the energy subsystem indicators over the years and the evaluation table of the energy subsystem evaluation results are analyzed and summary. The experimental results show that the correlation coefficients between the selected indicators are all less than 0.7, that is, the correlation between the indicators is weak, and there is no strong correlation indicator (repetitive indicator). Energy consumption structure, improve energy efficiency, and improve the energy efficiency evaluation system model.
