Its their own new proprietary interconnect, runs at 80Gb/s (similar
speed to IB 8x), switches are low port count. What the article missed is
that they are also using their own CPUs and host chipset (along with
Intel) in that system as well.

"wrests", bah.  you get exactly the rank on top500 that you pay for.

this url:

mentions 160 Gbps as the speed of the interconnect, but also says 
"twice QDR".  afaik QDR is 40 GB before encoding, so Galaxy would 
be 80, not 160.

anyone have further details on what the "galaxy" interconnect is?
