History

Japanese

RIKEN Center for Computational Science (R-CCS) (previously Advanced Institute for Computational Science (AICS)) was established in July 2010 with aims to operate the K computer as a shared facility, collaborate and integrate the fields of computational science and computer science, as well as to form an international research base for advanced scientific studies and technological breakthroughs.

The K computer was positioned as the core of innovative high performance computing infrastructure (HPCI)The webpage will open in a new tab. promoted by the Ministry of Education, Culture, Sports, Science and Technology, and had been utilized by many researchers and industrial users for about seven years since its launch in September 2012. It contributed tremendously to scientific development, and now Fugaku, its successor supercomputer, is playing the same role.

As a core base for the development of computational science in Japan, R-CCS collaborates proactively with research institutes and universities in the fields of computational science and computer science, both domestically and overseas, for research development and human capital development.
