Abstract:

From K to Post K: Great Opportunity and Great Challenge in Advanced Computing

RIKEN AICS is the Japanese flagship research institution in computational science, and is meant to be the COE for various simulation fields such as biology, physics, chemistry, weather and climate, disaster mitigation, cosmology, engineering, etc. We also focus on computer science research such as processor design and system software, as well as fundamental technologies including programming framework and visualization. The K computer is the general purpose massively parallel supercomputer and won the top position on TOP500 in 2011 achieving a LINPACK benchmark performance of 10 petaflops. On the latest TOP500, K is the 7th position but K is still one of the most powerful supercomputers in the world. Indeed K is still No.1 both on the Graph500 rankings and on the HPCG rankings. The architecture of the K balances processing speed, memory, and network. This guarantees high performance for whole area of science. More than 4 years have passed since the start of K operation. In many areas we see many great results. Many projects that use the K computer would be difficult or impossible to do elsewhere. Now the K computer is being used in many different fronts and extending the boundaries of computational science. K is providing great opportunity and great challenge in advanced computing. Supercomputer has become a fundamental technology which supports the society today, and pioneers the society of tomorrow. Continued development of world top-class supercomputer is vital for the world leadership in science and technology. AICS is now developing a world’s top-class supercomputer, “post K” launching in around 2020 to spearhead the quest for knowledge of human kind. An overview of the Japan's HPC and some highlights of results obtained by using K will be given in my talk.

Biography:

Kimihiko Hirao was born in November 9, 1945 in Niihama, Japan. He obtained his B.S. degree in 1969 and the Ph.D. degree in 1974 both from Kyoto University, Japan. He worked as a Professor at Nagoya University in 1988 and moved to The University of Tokyo in 1993. In the period 1989-1990 and 2002-2003, he served as a Visiting Professor at the Institute for Molecular Science (IMS). Hirao also worked as a Visiting Professor at the University of the Air from 2003 to 2007, the Dean of the School of Engineering, The University of Tokyo from 2004 till 2006, and the Vice President of the University of Tokyo since 2007. In addition, he is the Fellow of the International Academy of Quantum Molecular Science (2002), the Fellow of the World Association of Theoretically Oriented Chemists (2002), and the President of Asian-Pacific Association of Theoretical and Computational Chemists (since 2003). He authored more than 300 scientific articles in Theoretical Chemistry.
