"Global Lambdas for Particle Physics Analysis" - Bandwidth Challenge
Supercomputing 2005 - Seattle
Caltech Booth 428. SLAC/FNAL Booth 302
We reached a peak speed of 151 Gbits/sec aggregated across the waves connected to the CACR and SLAC/FNAL Booths. We sustained > 100Gbits.sec for more than four hours, equivalent to transferring over one PetaByte in a day. The network traffic was generated by a rich mixture of real physics applications, including bbcp, xrootd, Clarens, Root, gridftp and dCache transfers. We used FAST TCP predominantly, as well as vanilla TCP stacks.
Harvey's presentation, giving full details of the event and partners, is here (~10MByte).

Synopsis (as prepared for HP's booth):
entry will demonstrate high speed transfers of physics data between host labs
and collaborating institutes in the USA and worldwide. Caltech and FNAL are
major participants in the CMS collaboration at CERNís Large Hadron Collider (LHC).
SLAC is the host of the BaBar collaboration. Using state of the art WAN
infrastructure and Grid-based Web Services based on the LHC Tiered Architecture,
our demonstration will show real-time particle event analysis requiring
transfers of Terabyte-scale datasets.
