  1. Brains to Bays --Scaleable Visualization Toolkits Arthur J. Olson Interaction Environments Thrust Area Leader Professor, Molecular Biology The Scripps Research Institute La Jolla, CA

  2. Evolution of Alpha Project • IE Thrust Area Vision • User Community feedback • State of art challenges • Successful projects/prototypes • Successful and important applications • Strong inter-thrust linkages

  3. IE Thrust Area Vision Provide a customizable collaborative scientific computing environment to explore data, facilitate simulation, and communicate ideas in groung-breaking research

  4. User Community Feedback • #1 Priority --Visualization Toolkits • Aid in the exploration of scientific data and simulations • Communicate results to the broader community • Scaleable from desktop to teraflop systems

  5. Important Infrastructure Challenge • Large DataVisualization • Parallel Visualization-- computing resources • Interactive Navigation -- client/server control • Compression/processing -- out-of-core manipulation • Combining data at multiple scales

  6. Successful projects/prototypes • IE Thrust • MPIRE -massively parallel volume rendering -- SDSC • VisualEyes -- multi-modal visualization and analysis toolkit -- U. Texas • Déjà vu -- platform independent viewing component -- TSRI

  7. Successful and important applications • Brain mapping -- Understanding the nature of the human brain -- Toga, Ellisman, et al. • Ocean modeling -- Simulating and predicting the long range nature of global climate change -- Wunsch, et al.

  8. Strong Cross Thrust Linkages • Data Intensive -- SRB, MCAT, XML • Metasystems -- Legion • Parallel Tools -- ADR, KELP • EOT -- Materials transfer for teaching
