最近为了实现Exa-flops下一代计算机系统，功耗成为重要问题。另一方面，现在不太考虑应用程序的功耗特性。在本研究中，我们检查了全球磁层磁流体动力学 (MHD) 仿真代码的功耗特性，以评估并行计算机系统上 CPU 功耗上限下仿真代码的功耗行为。结果证实，MHD仿真代码中存在不同的功耗部分，这些部分在CPU功率上限下执行性能下降或没有变化。这表明了通过功率上限进行性能优化的能力。
Recently to achieve the Exa-flops next generation computer system, the power consumption becomes the important issue. On the other hand, the power consumption character of application program is not so considered now. In this study we examine the power character of our Magneto hydrodynamic (MHD) simulation code for the global magnetosphere to evaluate the power consumption behavior of the simulation code under the CPU power capping on the parallel computer system. As a result, it is confirmed that there are different power consumption parts in the MHD simulation code, which the execution performance decreases or does not change under the CPU power capping. This indicates the capability of performance optimization with the power capping.
