The Information Technology Center (ITC) (https://www.itc.u-tokyo.ac.jp/en/) was organized in 1999, and it consists of 4 research divisions (Campus-wide Computing, Data Science, Network, and Supercomputing). ITC is also a core organization of the “Joint Usage/Research Center for Interdisciplinary Large-Scale Information Infrastructures (JHPCN)” , and a part of HPCI (the High-Performance Computing Infrastructure) operated by the Japanese Government. The Supercomputing Division, Information Technology Center, The University of Tokyo (http://www.cc.u-tokyo.ac.jp/) was originally established as the Supercomputing Center of the University of Tokyo in 1965, making it the oldest academic supercomputer center in Japan. ITC was organized in 1999, and the Supercomputing Center became the Supercomputing Division (SCD) of the ITC. The three main missions of SCD/ITC are (i) Operations of Supercomputers & Services, (ii) Research & Development, and (iii) Education & Training. Currently, SCD/ITC consists of about 10 faculty members. SCD/ITC is now operating two supercomputer systems, “Massively Parallel Supercomputer System (Oakbridge-CX)” by Fujitsu with 6.61 PFLOPS, and “Integrated Supercomputer System for Simulation, Data and Learning (Wisteria/BDEC-01)” by Fujitsu with 33.1 PFLOPS. The two systems operated by SCD/ITC have 2,600+ users; 55+% of these users are from outside the university. Hands-on tutorials for parallel programming (on-line) are held 20+ times per year. Up to 10% of the total computational resources of each system are open to users from the industry.
