3. 20 July 2005 3 Open Science Grid Operating OSG, Olson, Milwaukee The Roles OSG Doc 47 Logical View Users (scientists, students, engineers, …) and Applications e.g. VDT (Globus, Condor, …) Compute, storage, (network in future) Catalog, discovery, identity, brokering, … (see later slides)

4. 20 July 2005 4 Open Science Grid Operating OSG, Olson, Milwaukee Roles (II) Physical View Real support organizations often play multiple roles Lines represent communication paths and, in our model, agreements. We have not progressed very far with agreements yet. Gray shading indicates that OSG Operations composed of effort from all the support centers.

5. 20 July 2005 5 Open Science Grid Operating OSG, Olson, Milwaukee Roles (III) Physical View Have recognized need for general open support, but no one is contracted to provide it, so a “best effort” community support activity has started and is still taking shape. See Fred Luehring & Burt Holzman. Community Support
