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.

Note:
First prize for the SC|05 Bandwidth Challenge went to the team from CalTech, Fermi and SLAC for their entry "Distributed TeraByte Particle Physics Data Sample Analysis," which was measured at a peak of 131.57 Gbps of IP traffic. This entry demonstrated high-speed transfers of particle physics data between host labs and collaborating institutes in the USA and worldwide. Using state-of-the-art WAN infrastructure and Grid Web Services based on the LHC Tiered Architecture, they showed real-time particle event analysis requiring transfers of Terabyte-scale datasets.
