"Among the world's fastest-500 supercomputers, Cplant Cluster --
the one at Sandia National Labs in Albuquerque, New Mexico -- ranks
"The 44th spot might not sound like a big deal, but Sandia
computer researchers say otherwise -- mainly because Cplant is one
of the few on the list that are "homemade...."
"The Sandia scientists wrote customized communication software
to get the off-the-shelf computers talking at maximum speed. Then
they developed their own utilities and used the Linux operating
system for networking."
