  1. CUMULVSDemonstrationNeSSI Workshop Dr. James Arthur Kohl Computer Science and Mathematics Division Oak Ridge National Laboratory October 14, 2003 12:30pm – 1:00pm Research sponsored by the Applied Mathematical Sciences Research Program, Office of Mathematical, Information, and Computer Sciences, U.S. Department of Energy, under contract No. DE-AC05-00OR22725 with UT-Battelle, LLC.

  2. Potential Benefits fromComputer Science Infrastructure: • On-The-Fly Collaborative Visualization • Interactive Access to Intermediate/Online Results • Remote Monitoring of Experiment by Team • Comparative Analysis of Model and Experiment • Computational Steering • Apply Visual Feedback to Alter Experiment Course • “Close Loop” on Experimentation Cycle • (Instrument Control…?)

  3. Note: NOT a Climate Modeling Tool…  (Collaborative, User Migration, User Library for Visualization and Steering) • Collaborative Infrastructure for Interacting With Scientific Simulations (or Experiments) • Middleware for Run-Time Visualization • Multiple, Independent Viewers (Several Provided) • Can Be Geographically Distributed… • Attach as Needed, Minimize Overhead • Coordinated Computational Steering • Heterogeneous Checkpointing / Fault Tolerance • Coupled Models… (Verification vs. Live Data?)

  4. Collaborative Combustion Simulation
