Abstract

Presently the power consumption of supercomputer system becomes a critical issue to develop the exascale supercomputer system. On the other hand, the power consumption character of applications is not so considered by the applications developers because their main interest is how fast to run their applications. In this study, we examine and evaluate the power consumption behavior of our Magnetohydrodynamic simulation code which solves the planetary magnetosphere under the constrained power of CPU and DRAM on the x86 computer system. As the results, we found there are some regions in the simulation code which decrease the calculation performance or do not affect the performance under the power capping. This indicates the capability of power optimization without performance degradation using the dynamic power capping in running the application. In addition, we obtained the specific power consumption combinations between CPU and DRAM which greatly affect the calculation performance.
