Analysis of the Characteristics and Development Trends of the Next-Generation of Supercomputers in Foreign Countries (report by IDC): International Data Corporation (IDC) was commissioned by RIKEN to produce a report on global trends of next-generation supercomputers (period of survey: May to December, 2016).

The report analyzed supercomputers of various architectures regarding their hardware, software, R&D, systems, costs, and user facility, as well as certain topics shared by regions and countries (such as power consumption), and issues that are specific to certain locations.

Note: The information and views set out in this publication are those of the author (IDC) and do not necessarily reflect the official opinion of RIKEN. RIKEN does not guarantee the accuracy of the data included in this study.

A special study of the ripple effects of the K and the post-K (report by IDC): From April to December 2016, IDC (International Data Corporation) investigated the ripple effects of using the K computer and the post-K computer through an evaluation of the financial return-on-investment (ROI) and scientific return-on-research (ROR), using the same methodology applied in similar studies for the US Department of Energy (DOE) and the EU.

The results showed a much higher cost saving ROI compared to other countries, generated by cost savings in such areas as disaster research related to earthquakes and tsunamis, and on the effectiveness of high-cost cancer drugs.

It was also found that Japan leads other countries in ROR innovations, due in part to the priority placed on long-term (5-year) research in national strategic programs and key technologies.

The results of the IDC study were reported at a meeting of the 6th MEXT evaluation committee for the K computer held on December 5, 2016.
