4 4 IWLSC, Kolkata India 2006 Jérôme Lauret for the Open Science Grid consortium Once upon a time in America … Trillium Meeting, May 20 th 2004 In the U.S., three big Grid collaborationIn the U.S., three big Grid collaboration –iVDGL (International Virtual data Grid Laboratory) –GriPhyn (Grid Physics Network); VDT –PPDG (Particle Physics Data Grid) Met with two primary goals –Identify and Plan for Joint Projects for 2004 i.e. “Grid2003(s) for 2004” –Bring into initial existence the Open Science Grid Consortium

5 5 IWLSC, Kolkata India 2006 Jérôme Lauret for the Open Science Grid consortium Open Science Grid Build on and evolve Grid3 towards a sustained production common grid infrastructure through “grass-roots” collaboration. Goals –Continue collaboration of US-ATLAS & US-CMS. Provide base for US Grid contributions to LHC –Expand Grid3 participants and users to all PPDG and to all HENP experiments. –Support existing VO in the Trillium (CDF, D0, STAR, –Invite and encourage other sciences to participate, contribute and benefit: molecular biology, genetics, protein chemistry, nanotechnology, climate, geophysics of the earth and the hydrodynamics of the ocean, human reasoning, economics, natural language processing, behavioral psychology, geographic information science and many more. –Invite partners across the world to “plug” to a common, scalable and shared infrastructure
