Are the 6-Way machines that are in question the Western Scientific
"SuperCluster" servers ( www.wsm.com )?  If so, these are actually three
Dual-CPU nodes in a 1U case.  The arguments about power might still hold
but a lot of other stuff ( Memory bandwidth, etc) goes out the window.

The cost per Gflop still might make the P4's attractive.  I don't know the
prices.  

If the machines that you are talking about really are 6-Way SMP nodes,
what are they?
