Molecular dynamics simulations are widely used for sim ulating the motion of molecules in order to gain a deeper understanding of chemical reactions, fluid flow, phase tran sitions, and other physical phenomena due to molecular in teractions. However, these simulations require huge com puter resources. In addition, the problem of energy con sumption must be solved. Recently, GPGPU has attracted attention as a possible solution to these problems. In this paper, we performed molecular dynamics simulations on a CPU and GPU, and compare calculation time, power con sumption and energy consumption results between them.
