4. 4 MAGIC for addressing the coordination problem? A team under the Large Scale Network (interagency coordination) Meets Monthly (1st Wed of each month) Federal participants ANL, DOE, LANL, LBL, NASA, NCO, NIH, NIST, NOAA, NSF, PNL, UCAR Other participants Boeing, Cisco, Educause, HP, IBM, Internet2, ISI, Level3, Microsoft, U-Chicago, UIUC, U-Wisconsin Workshop held in Chicago, Aug 26-28 editors, contributors and participants from Federal Government, agencies and labs; industry, universities, and international organizations ~100 participants “Blueprint for Future Science Middleware and Grid Research and Infrastructure” Middleware And Grid Infrastructure Coordination

5. 5 Driving Factors for Middleware and Grids New classes of scientific problems are enabled from technologies development High energy physicists will harness tens of thousands of CPUs in a worldwide data grid On-line digital sky survey requires mechanisms for data federation and effective navigation Advances in medical imaging and technologies enable collaboration across disciplines and scale Coupling of expertise, collaboration, and disciplines encourage the development of new science and research. Continuing exponential advances in sensor, computer, storage and network capabilities will occur. Sensor networks will create experimental facilities. PetaByte and ExaByte databases will become feasible. Increase in numerical and computer modeling capabilities broaden the base of science disciplines. Increase in network speeds makes it feasible to connect distributed resources as never before. Science Push Technology Pull
