100G: it may be voodoo, but it certainly works


SC10, Thursday morning.

During the SC10 conference, NASA, NOAA, ESnet, the Dutch Research Consortium, US LHCNet and CANARIE announced that they would transmit 100Gbps of scientific data between Chicago and New Orleans.  Through the use of 14 10GigE interconnects, researchers attempted to  completely utilize the full 100 Gbps worth of bandwidth by producing up to twelve 8.5-to-10Gbps individual data flows.

Brian Tierney reports: “We are very excited that a team from NASA Goddard completely filled the 100G connection from the show floor to Chicago.  It is certainly the first time for the supercomputing conference that a single wavelength over the WAN achieved 100Gbps. The other thing that is so exciting about it that they used a single sending host to do it.”

“Was this just voodoo?” asked NERSC’s Brent Draney.

Tierney assures us that indeed it must have been… but whatever they did, it certainly works.
