Abstract

Speaker: Satoshi Matsuoka, Global Scientific Information and Computing Center, Department of Mathematical and Computing Sciences, Tokyo Institute of Technology

HPCI is the Japanese High Performance Computer Infrastructure, which encompasses the national operations of major supercomputers, such as the K supercomputer and Tsubame2.0, much like the XSEDE in the United States and PRACE in Europe. Recently it was announced that the Japanese MEXT (Ministry of Education, Culture, Sports, Science and Technology) is intending to initiate a project towards an exascale supercomputer to be deployed around 2020. However, the workshop report that recommenedt the project also calls out for a comprehensive infrastructure where a flagship machine will be supplemented with leadership machines to complement the abilities of the flagship. Although it is still early, I will attempt to discuss the current status of Tsubame2.0 evolution to 2.5 and 3.0 in this context, as well as the activities in Japan to initiate an exascale effort, with collaborative elements with the US Department of Energy partners in system software development.
