Distributed TeraByte Particle Physics Data Sample Analysis Session: Bandwidth Challenge Showcase: Stretching the Bounds of Network Capacity Event Type: Bandwidth Challenge Time: 10:40am - 10:50am Speaker(s): Julian James Bunn, Harvey Newman, Les Cottrell, Don Petravik Location: 611-614 Abstract: The Caltech-CERN-Florida-FNAL-Michigan-Manchester-SLAC entry will demonstrate high speed transfers of particle physics data between host labs and collaborating institutes in the USA and worldwide. Caltech and FNAL are major participants in CERN’s CMS experiment at the LHC. SLAC is the host of the BaBar collaboration. Using state of the art WAN infrastructure and Grid Web Services based on the LHC Tiered Architecture, we will show real-time particle event analysis requiring transfers of Terabyte-scale datasets. We aim to maximize the utilization of the available waves to and from the Seattle show floor. The traffic will consist of a realistic mixture of streams: transfers of TeraByte event datasets, and sets of background flows of varied character to absorb remaining capacity. This will simulate the environment in which distributed physics analysis will be carried out at the LHC. We expect to easily beat our SC2004 record of ~100Gbits/sec (roughly equivalent to downloading 1000 DVDs in less than an hour).
