e-Science in high energy density science research

We present three achievements related to e-Science in high energy density science research. We have developed a test module of new data base system for nation-wide users of the high power lasers at Osaka University with web technology, flexible control system and XML-database, which provide efficient, accurate and flexible R&D processing. We also constructed a EUV-GRID portal system for integrated computer simulations of laser produced plasma–extreme ultraviolet (LPP–EUV) light source development, which provides flexible framework for automatic sequencing of workflow for the integrated simulations. A dynamical domain decomposition method in molecular dynamic (MD) simulations is required to obtain a good adaptive load balancing for heterogeneous computing environments such as grid. We have developed a new algorithm of the dynamical domain decomposition. We successfully performed large scale MD-message passing interface (MPI) simulations on cluster computers connected through Super-SINET using the National Research Grid Initiative (NAREGI GRID) grid middleware and the new algorithm.
