Pioneering the Computing Services for Academic Studies in Japan

1. Pioneering the Computing Services for Academic Studies in Japan • Mission • 40 Years of HPCServices • Though the R. I. I. T. is a newly-established institute (founded in 2007), its computing services have a long history, nearly 40 years. It was formerly known as "Computer Center" or "Computing and Communications Center". Since the early days of the Computer Center, it has been one of the seven national supercomputer centers in Japan. • High-Performance Computing is now an essential tool for various fields of science. It shows us what we cannot see in a laboratory, such as turbulences in the supersonic stream around turbine blades of a jet engine, or the mantle convection inside our own planet. • User Support • Computer centers usually have professional staff supporting users in programming, debugging or performance tuning. However, they usually do not know much about various research fields such as materials engineering or molecular science. • To bridge the gap between Computational Science and Computer Science, the R. I. I. T. has computational scientists and computer scientists working together. The unique collaboration of these two types of experts is the key to their cutting edge to assist users in the fundamental part of studies. • The Research Institute for Information Technology(R. I. I. T.) of Kyushu University consists of scientists and supporting employees, but it is not just a "pure" institute. Though it is related to various aspects of information technology, its mission also includes the following IT-related services and studies: • network services for the university; • other IT-related campus-wide services; • high-performance computing services; • advanced studies for the future of these services.
