Colloq: Abstract: 
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 recommended 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.
Colloq: Speaker Bio: 
Satoshi Matsuoka is a Professor at the Global Scientific Information and Computing Center of Tokyo Institute of Technology (GSIC). He is the leader of TSUBAME series of supercomputers, which became the 4th fastest in the world on the Top500 and awarded the "Greenest Production Supercomputer in the World" by the Green 500 in November, 2010 and June 2011. He has also co-lead the Japanese national grid project NAREGI during 2003-2007, and is currently leading various projects such as the JST-CREST Ultra Low Power HPC and JSPS Billion-Scale Supercomputer Resilience. He has authored over 500 papers according to Google Scholar, and has chaired many ACM/IEEE conferences, including the Technical Papers Chair, Community Chair, and the upcoming Program Chair for Supercomputing Conferences 09, 11 and 13 respectively. He is a fellow of ACM and European ISC, and has won many awards including the JSPS Prize from the Japan Society for Promotion of Science in 2006, awarded by his Highness Prince Akishinomiya, the ACM Gordon Bell Prizes for 2011, and the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology in 2012.
