Ideas Computers -- What size when - Parallel ? - Shared or Distributed (larger) Application Area - 3D Simulations - "Intelligent" Datamining (data from nature or model) - Crisis Management/Training Application Software - Individual or Group (as in Japan) - Qualitative Structure "Irregular FEM" "Fast Multipole" Systems and Tools Software - MPI - Grid Generation - Multipole - Visualization Data Storage and Access Education and Training - Parallel Computing - Training -- Teach MPI - Education Systems Integration - PSE/Toolkit (web-based portal) - (XML) Standards for data / program interfaces Can one integrate US and Japanses/Australian "programs" Is it Innovative Is there anything special needed to be done or will MHPCC/Ames/PACI suffice Data Explorer Free Computational Steering Immersive PDE Solvers Group Approach 1) Rupture Dynamics -- link waves in bulk; complex boundaries (lot of Jazpan/Australia Interest) 2) NASA Data Support 3) Real Time Issues Mora wants "plug and play" bulk/surface codes Lessons from other fields? (Minster) Australia/Japan collaboration including code linkage at boundaries Unclear how to set up "Steve Day" problem -- is it ready to go yet. Doubt it Bosl: Component Technology Can we define interface between volume and boundary simulations (boundary = fault) SCEC ************ 3 year proposal ********************** 1) Micro Scale Calculate Friction 2) Meso Scale Rupture Dynamics and link to Earthquake Dynamics Scenarios What about CMU Group? 3) Macro Scale Large Systems What about IT? Education (Jordan likes but others not much interest) Mora: doesn't agree - believes in more ambitious program Japan: $600M Computer over 5 years $30M Software over 5 years China $100 million yuan over ? years SCEC $5.5M year Deliberatley disorganized approach to Science
