HPCI, the innovative High-Performance Computing Infrastructure, is a world top class supercomputing infrastructure built by the Japanese government. In the HPCI, the flagship system, Fugaku, and the systems of major universities and national laboratories throughout Japan are connected via a high-speed network.
This website introduces activities of the HPCI including the supercomputer Fugaku, and research achievements by awarded projects.

HPCI, Your Gateway to HPC

HPCI is open to the world. Applications from all researchers are welcome, from academia to industry*1. This site also outlines public call for projects which can access the HPCI supercomputing resources including the supercomputer Fugaku.
*1 PI from industry needs to belong to a private company registered in Japan.

About US

Research Organization for Information Science and Technology (RIST) is a general incorporated foundation which has been carrying out usage promotion services of the Japanese flagship computers (first the K computer, then the successor supercomputer Fugaku since 2020), commissioned by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), since 2014. Our scope includes project selection, user support, and help spreading research results of projects. In addition, since 2017, RIST has also taken a role as the operation office of the innovative High-Performance Computing Infrastructure (HPCI). Within a framework of HPCI, we are in charge of managing computational resources and promoting usage.
