  3. Analytic Molecular Dynamics Monte Carlo Mesoscopic Time 10-14 sec Years Space 10-10 m 10-1 m From Molecule to Man… • First Principle Modeling • Genetic Regulatory Networks • Metabolic Networks • Immunological Networks • … Silicon Cell • Hierarchical data Modeling • G-P-M & Patient Dbases AI – GA’s, NN’s, Fuzzy L. Molecule Man

  4. Time 10-14 sec Years Space 10-10 m 10-1 m From Molecule to Man…GRID • High Performance Computing => Mesoscopic Simulation • High Throughput Computing => Parameter Space Exploration • Data Disclosure => Dbase Federation and Integration • Data Fusion => Parameter Transfer • Access => Visualization/VR && Roaming and Remote &&PDA

  5. X#

  6. What DRIVeS the X# ? • Distributed • Real-time • Interactive • Visualization • (E) • Simulation

  7. Goal of WP 1 • Applications in health and environment • Data gathering, processing and interpretation in geographically distributed locations • Fast, interactive decision making • Interactive access to distributed • Databases • Super computers and High Performance Clusters • Visualisation engines • Medical scanners • Environmental data input devices

  8. CrossGrid structure The applications are rooted in the underlying common environment. The more they share, the firmer the stand. Distinct Applications (WP 1) Application programming environment (WP 2) New grid services (WP 3) General grid services (a.o. Globus)

  9. -Links with European National efforts - Links with US projects (GriPhyN, PPDG, iVDGL,…) Applications EGSO CROSSGRID GRIA EUROGRID DATAGRID GRIP GRIDLAB DAMIEN Middleware & Tools DATATAG Underlying Infrastructures Industry / business Science A new IST Grid project space (Kyriakos Baxevanidis)

  10. Three central functionalities • Data gathering • Data generators and data bases geographically distributed • Selected on demand • Processing • Needs large processing capacity on demand • Interactive • Presentation • Complex data require versatile 3D visualisation • Support interaction and feedback to other components

  11. WP 1 structure Task 1.1 Surgery planning & visualisation Task 1.2 Flooding control MIS Task 1.3 HEP data analysis Task 1.4 weather & pollution modelling Task 1.0 Co-ordination & management

  17. WP 1.1 • Nature March 2002

  18. Some Key Data for WP 1.1 • New Scanners 1024 x 1024 • 128 slices of 2 byte depth==> 256 MByte • 10 images per systole= 1 per second

  19. Design Considerations • High Quality presentation • High Frame rate • Intuitive interaction • Real-time response • Interactive Algorithms • High performance computing and networking… • Distributed Resources and Data

  20. Runtime Support • Need generic framework to support modalities • Need interoperability • High Level Architecture (HLA): • data distribution across heterogeneous platforms • flexible attribute and ownership mechanisms • advanced time management

  21. Provoking a bit… Progress in natural sciences comes from taking things apart ... Progress in the X# comes from bringing things together...
