Caltech, SLAC and FNAL use advanced networks to demonstrate analysis tools that will enable physicists to control worldwide grid resources when analyzing major high-energy physics events. Components of this “Grid Analysis Environment” are being developed by such projects as UltraLight, FAST, PPDG, GriPhyN and iVDGL. The iGrid demonstration shows how a physicist can issue on-demand network and resource provisioning in response to event analysis requests from his desktop computer. A request’s complex workflows are translated using provisioning algorithms into network flow allocations and scheduled resource bookings on remote computers / clusters. Caltech’s MonALISA monitoring framework illustrates the progress of the analysis tasks, data flows in the network, and the effects on the global system.
