6. August 2007 Requesting Allocations of Time TeraGrid resources are provided for free to academic researchers and educators Development Allocations Committee (DAC) for start-up accounts up to 30,000 hours of time are requests processed in two weeks - start-up and courses Medium Resource Allocations Committee (MRAC) for requests of up to 500,000 hours of time are reviewed four times a year Large Resource Allocations Committee (LRAC) for requests of over 500,000 hours of time are reviewed twice a year

7. August 2007 TeraGrid Usage 33% Annual Growth Specific AllocationsRoaming Allocations 200 100 Normalized Units (millions) TeraGrid currently delivers an average of 420,000 cpu-hours per day -> ~21,000 CPUs DC Dave Hart (dhart@sdsc.edu)

9. August 2007 Science Gateways Broadening Participation in TeraGrid Increasing investment by communities in their own cyberinfrastructure, but heterogeneous: Resources Users – from expert to K-12 Software stacks, policies Science Gateways –Provide “TeraGrid Inside” capabilities –Leverage community investment Three common forms: –Web-based Portals –Application programs running on users' machines but accessing services in TeraGrid –Coordinated access points enabling users to move seamlessly between TeraGrid and other grids.
