The Information Technology Center at Nagoya University began with the general purpose computer Fujitsu FACOM230-60 in 1971. A supercomputer was first installed in 1987 and has since been used by a number of researchers in the field of scientific computing. We installed the new-system Supercomputer "Flow" and started computing services in July 2020. We support academic research at a wide range of universities and other institutes by supplying services such as computing that accommodates researcher demand for large-scale computing, "Post Processing" to enable visualization, computer statistics, big data mining, "Data Intensive Computing" to provide new services in distributed data processing, distributed databases, and small virtual computers for laboratories. As a partner institute in the Joint Usage/Research Center (JHPCN) in Japan since 2010, we have played a role in the research and development of high-performance computing technology.
Furthermore, since 2010, we have participated in a joint research project in cooperation with the Institute for Space-Earth Environmental Research (ISEE) at Nagoya University to promote academic research and advanced technology in high-performance computing in fluid, plasma, machine learning, and general computational science. Moreover, since 2012, we have worked as resource providers for the High Performance Computing Infrastructure (HPCI) in Japan, helping to accelerate a wide range of HPC utilization from exploratory research to large-scale and industrial research, to enlarge and foster the computational science community, and to utilize the best achievements for the good of society by matching needs and available resources on a nationwide scale.

History of ITC-NU
- 1971 Nagoya University established Computation Center (NUCC), and installed Fujitsu FACOM 230 series for national joint use.
- 1979 NUCC began computing services using Fujitsu FACOM M series.
- 1987 NUCC acquired Fujitsu FACOM VP series of the vector supercomputer, and launched high‐performance computing service.
- 1995 NUCC updates supercomputer to Fujitsu FACOM VPP series. VPP500/42 was ranked 12th in the 6th TOP500 list (1995, Dec.), and VPP5000/56 was ranked 25th in the 7th TOP500 list (1996, Jun.).
- 2000 Fujitsu GP7000F/90, NUCC's first SPARC64 system, was installed.
- 2002 NUCC was reorganized into the Information Technology Center, Nagoya University (ITC‐NU).
- 2005 ITC‐NU installed a scalar‐type supercomputer system, Fujitsu HPC2500 with a peak performance of 14 Tflops. It was ranked 41th in the 25th TOP500 list (2005, Jun.).
- 2009 For diversified computing demand, ITC‐NU installed Fujitsu HX600 by T2K open supercomputer specification, and Fujitsu M9000 of large SMP system. ITC‐NU installed Fujitsu FX1 with a peak performance of 30 Tflops.
- 2010 ITC-NU is certified as one of the Joint Usage/Research Center for Interdisciplinary Large-scale Information Infrastructures (JHPCN).
- 2013 ITC‐NU installed Fujitsu FX10 with a liquid‐cooled system, and a petabyte-scale distributed storage system. Fujitsu CX400, oome of the nodes equip many-core co-processor (KNC) was installed.
- 2014 ITC‐NU launched Visualization Lab with SGI UV2000 and an 8K tiled display system.
- 2015 ITC‐NU updated the supercomputer system to Fujitsu FX100 with a peak performance of 3.2 Pflops. FX100 was ranked 21st in the 46th TOP500 list (2015, Nov.), and also 12th in HPCG (2015, Nov.).
- 2020 To meet the increasing computational demand on both large‐scale numerical simulation and data science, ITC‐NU installed Supercomputer "Flow", a complex supercomputer system, consisting of four compute subsystems and two storage systems with the total peak performance of 15.9 Pflops.
