Learning Computer Simulation with an MDGRAPE Accelerator Tetsu Narumi 1, Fumikazu Konishi 2, Ryo Umetsu 2, Makoto Taiji 2, Toshikazu Ebisuzaki 3, Kenji Yasuoka 1 1 Department of Mechanical Engineering, Keio University 2 Genomic Sciences Center, RIKEN 3 Computational Astrophysics Lab., RIKEN

Background Computer Simulation becomes important Fluid dynamics (Car, Airplane) Structural analysis (Building, Mobile phone) N-body simulation (Droplet of inkjet printer) Little experience on simulation at school Hands-on Simulation

N-body Simulation Astrophysical simulation Galaxy collision Cosmology Molecular dynamics simulation Bio sciences (protein folding) Nano sciences (carbon nano tube) Requires Huge Computational Power

Tool for Simulation : MDGRAPE Accelerator for N-body simulation Gravitational or molecular dynamics simulation Fast and good performance/cost Developed by University of Tokyo, RIKEN, NAOJ Host Computer (PC) Accelerator (MDGRAPE) Force calculation Newtons Equations of Motion, etc. Positions Forces

MDGRAPE at Hand Expensive hardware Freely distributed by RIKEN Difficult to use All-in-one CDROM (Bootable, Device driver, Demos, Sources) MDGRAPE-2 Board

Demonstration Astrophysical simulation Galaxy collision Developed by Toshiyuki Takahei Molecular dynamics simulation NaCl Developed by Takahiro Koishi, Fukui Univ. OS : Customized KNOPPIX CD bootable linux ( Customized by Ryo Umetsu, RIKEN GSC

Summary Propose Hands-on Simulation Learning simulation at school is important Tools for N-body simulation are ready Free MDGRAPE-2 board All-in-one CDROM Need Help for Making Contents, Lecturing at School etc.
