Final report

The final report on high-end computing in Japan is available in PDF format. ( ~ 11.7 MB )
Individual chapters are also available.


While the Earth Simulator itself is fairly well known, the main task for this study is to determine what comes after the Earth Simulator in Japan. The WTEC panelists will address this task by gathering information and analyses from a variety of sources: (a) their own existing knowledge of and insights into U.S. and Japanese HEC R&D activities; (b) a review of the published literature and any "gray literature" reports that can be found on the subject; (c)
correspondence with U.S. and Japanese colleagues, as part of a careful process of preparation for the Japan site visits; (d) a week of site visits in Japan, following several months of careful preparations for those visits; (e) a
workshop at which the panelists present their preliminary findings and receive comments on those findings from sponsors, U.S. colleagues, and invited Japanese site visit hosts and, (a) reviews of the panel's draft site reports and draft final report by the sponsors and Japanese hosts. After collecting all this information, the WTEC expert panelists add their own analyses and report their findings back to the U.S. government sponsors in the most timely manner
possible. The details of the study scope will be agreed on at the study kickoff meeting, in consultation with both panelists and sponsors. A preliminary list of issues to be covered might include the following:
