To know the effective performance of A64FX, the evaluation using the MHD simulation code of planetary magnetosphere (not benchmark code) has been conducted. As the results, the execution efficiency of A64FX become higher than the Xeon Phi KNL which configuration resembles A64FX and achieved the good effective performance compared to the latest Xeon.
