Toward Formation of the International Hub of Computational Sciences
The Center for Computational Sciences (CCS) conducts research activities grounded in the central concept of “Multidisciplinary Computational Science” through collaboration and cooperation among various computer-related and scientific fields. The Liaison Office for Multidisciplinary Computational Sciences is a key part of the Center’s efforts aimed at maintaining its position as an international hub for computational science information.
■ Cooperation among Different Fields
In order to promote multidisciplinary computational science, cooperation among different fields is essential. In 2011, using the research results of first-principles electronic state calculation for 100,000 atom silicon nanowires using K computer, a research group from RIKEN, the University of Tsukuba, the University of Tokyo, and Fujitsu Limited won the Gordon Bell Prize for Peak-Performance, which is recognized as an outstanding achievement in high-performance computing. This is just one of the results of cooperation among different fields that have taken place at the Center in recent years.
■ International Cooperation
As for international cooperation, partnership agreements have been concluded between University of Tsukuba and the University of Edin- burgh in the UK, as well as with Lawrence Berkeley National Laboratory in the US. Furthermore, as part of the efforts to deepen the computational science research exchanges, the CCS and the University of Edinburgh Parallel Processing Center (EPPC) are currently hosting joint symposiums, and the Center is cosponsoring workshops with Lawrence Berkeley National Laboratory. Additionally, bilateral exchange joint research projects into computational materials science are being conducted with Vanderbilt University and the University of Washington in the US under the sponsorship of the Japan Society for the Promotion of Science (JSPS).
■ Multidisciplinary Pioneering Program
The Multidisciplinary Pioneering Program encourages the promotion of research efforts that require collaboration and cooperation among divergent scientific fields. For example, there is a current project underway that requires cooperation between the computational physics (science) and numerical analysis (engineering) fields in order to implement calculation code with high execution efficiency, and to perform the necessary large-scale simulations using the code. There are also projects that aim at new research deployments and developments by facilitating organic cooperation among different fields utilizing the same techniques in computational science.
This Multidisciplinary Pioneering Program has been carried out in conjunction with the collaborative multidisciplinary program of the center.
■ Organization for Collaborative Research on Computational Astrobiology
In the last decade, the field of “Astrobiology” has attracted a significant deal of attention owing to advanced observations of extrasolar planets as well as interstellar molecules. This organization aims at the creation of a computational astrobiology by exploring key processes related to the origin of life in the universe through ab initio calculations based on collaboration among the Computational Astrophysics, Computational Biology, Computational Planetary Science, and Computer Science fields.
These research efforts are targeted on the potentials of interstellar molecular biology, planetary biology, and the astrophysics of star and planet formation. At present, 51 researchers from 20 institutes are participating in the organization, which was formed at the initiative of the CCS, University of Tsukuba.
