Abstract

From the year 2000 to 2002, the super computer system located on Naka Fusion Research Establishment, Japan Atomic Energy Research Institute (JAERI) has been replaced. Since it is the massively parallel scalar computer with 768Gflops, the amount of data outputted from the numerical simulation becomes much larger and is about several hundred Gbytes. In this paper, which scientific visual analysis system is more useful to extract and understand physical phenomena from the large amount of data is investigated and the performance of the established system is estimated.From the year 2001, Information Technology-Based Laboratory (ITBL) project has progressed and its basic technology has been developed collaboratively between Center for Promotion of Computational Science and Engineering (CCSE), JAERI and Institute of Physical and Chemical Research. ITBL aims to construct the virtual collaborative research laboratory on SuperSINET, where large-scale simulations can be carried out as well as large-scale experimental institutions can be used through Internet. The visualization software PATRAS, which has been developed on ITBL, is introduced.
