FDPS is a library for massively parallel particle simulations, which has been developed by our team. The current released version of FDPS can generate a parallel code that scales up to the K computer (Iwasawa et al. 2015, PASJ, 68, 54). However, it is not clear that FDPS generate a scalable code in the next generation of supercomputers. In order to identify potential problems of FDPS and to improve FDPS more, we need to analyze FDPS in a system larger than the K computer. In late January, we started the development of FDPS on Sunway Taihulight, which is the most powerful supercomputer in the world (as of Nov. 2016, 125.4 PFlops). In this talk, I'd like to introduce the current status of this project.
