Objective of External Review (1)

The objective of the review is to receive an outside
examination on the research activities and their outcomes of
the Center in view of the founding objectives, and toincorporate the recommendations from the review for future
developments of the Center.
Timeframe to be evaluated: 2004 – 2007 (present)

In 2004, the center was re-organized from “center for computationalphysics” to “center for computational sciences”
On April 2004, the Japanese National University system underwent a
major transition. Their legal status was changed to that ofindependent institutes.
We have made 6-years plan (FY2004-FY2009). We need a mid-term
evaluation at this moment to make a plan for the next.

Inter-university Activities (1)① Acquire (and development) and operate leading-edge advanced

computing systems as inter-university facilities for large-scalecomputational scienceSince 1998 to September 2005, we have conducted “Large-scale simulationproject”. In this project, we has been inviting proposals, twice per year, forlarge-scale numerical research with CP-PACS, making the computational powerof the CP-PACS accessible to researchers throughout Japan. We accepted
proposals and allocated computing resources according to review result byreview committee including external reviewers.
From October 2007, we execute “Interdisciplinary Computational Science
Promotion Programs” to make the best use of PACS-CS.
The Interdisciplinary collaboration program is to promote interdisciplinary research
activities of different disciplines.
 The Large-scale scientific simulation program is to push forward the grand challengeof several fields in computational sciences by providing the computational power of
the PACS-CS.

Highlights of Researches in CCSCP-PACS Project(1992 – 1996 ): Developed the CP-PACS parallel computer (rankedas No. 1 in the Top 500 List of November 1996), which has produced ground-breaking
results in computational particle physics, astrophysics and condensed matter physics.

Research for the Future Project “Development of Next-Generation Massively
Parallel Computers” (1997-2001): Carried out basic research for high performance
processor and, developed the concept of Heterogeneous Multi-Computer System(HMCS) to integrate different type of computersThe project was extended into FIRST Project (2004 – 2007), which developed a specialpurpose simulator FIRST for pioneering large-scale astrophysical astronomical radiationhydrodynamic hydro-dynamics calculation.

PACS-CS Project (2005 – 2007): Developed a massively parallel cluster PACS-CS
with a peak performance of 14.3 Tflops. The system started operation in July 2006,and calculations are actively pursued to carry out several projects including nano- andbio-sciences and lattice QCD simulation, and climate simulation.
International Collaboration for global infrastructure on computational science toconnect major research sites such as ILDG (International Lattice Data Grid) for sharing
Lattice data world-wide.

Besides the above researches, researchers in CCS win several funds (Grand-in-Aid forscientific research by MEXT, JST-CREST) and conduct research projects actively.
