  1. Where do we go from here?---- KDI ASC Wai Mo Suen Washington University wms@wugrav.wustl.edu

  2. The Astrophysics Simulation Collaboratory:Enabling Large Scale Simulations in Relativistic Astrophysics PIs: U of ChicagoIan Foster • RutgersManish Parashar • UIUC Mike Norman John Shalf Ed Seidel • Wash U Wai-Mo Suen (lead PI) • Potsdam Ed Seidel

  3. Challenges of the Project (1)Build a Collaboratory based on Cactus that contains: General Relativitistic Astrophysics Codes AMR Advanced Viz Metacomputing capabilities (2) Build it as a useful tool for the whole community (3) The accretion collapse of a neutron star as the driving problem

  4. Distribution of Effort U Chicago Meta- Computing NCSA Advanced Viz Zeus Newtonian astrophysics codes Rutgers AMR Wash U/Potsdam Einstein-GRHydro-EOS codes Accretion collapse
