Interesting article. It prompted me to look up Cray, Inc.

 From Wikipedia>>>>

 >>>As of November 2009^[update]
<http://en.wikipedia.org/w/index.php?title=Cray&action=edit> , the
largest computer system Cray has delivered is the XT5 system at .^
<http://en.wikipedia.org/wiki/Cray#cite_note-nccs-jaguar-4>   National
Center for Computational Sciences at Oak Ridge National Laboratories.
This system, with over 224,000 processing cores, is dubbed "Jaguar" and
is the fastest computer in the world as measured by the LIN PACK
benchmark  with the speed of 1.75 petaflops.^
<http://en.wikipedia.org/wiki/Cray#cite_note-cnet-jaguar-6> It is also
the fastest system available for open science and the first system to
exceed a petaflops sustained performance on a 64-bit scientific
application.<<<
