Japan Atomic Energy Research Institute started the public competition research and development on software for computational science and engineering in 1997, and closed it in 2002. This report describes the system of the competition research and development, application situations, R & D subjects adopted, evaluation findings, outputs produced, achievements and problems, as a summative report of practice of the system for six years.

We present the implementation and performance evaluation results of the plasma physics simulation code called GT5D on a GPU cluster. In this study, an iterative matrix solver, which is identified as a performance bottleneck in the code, is tuned on the GPU. The measured performance is compared with attainable performance calculated by the roofline model. Additionally, we show the implementation with direction communications between GPUs for utilizing many GPUs.
