Last ten years the top performance of the fastest high-performance systems in the world increased more than thirty times. The energy efficiency of high-performance calculations became the most important because of the growth of carbon footprint from supercomputers. In this work, we will show the energy efficiency research of our plasma physics code. We propose the supercomputer’s carbon footprint value for typical plasma physics problem calculations as well as the method for evaluation of the power rate of the HPC code. We also provide information about the difference in energy efficiency between the AVX2 and AVX512 autovectorized programs.
