Compared to the previous system, the new plasma simulator performs more than eight times better, and that performance is the twelfth best in the world and the second best in Japan (performance benchmark; HPCG benchmark (as of June 2015)). In conducting deuterium plasma turbulence simulation in the LHD, in the old system calculation itself took more than 400 hours, and (from the beginning of the simulation until the final results were obtained) more than six months were necessary for the completion of all analyses. Using the new plasma simulator, calculation took 50 hours, and all analyses were completed in approximately one month, and regarding the many problematic conditions in the previous computer, it is now possible to undertake simulation analyses.
