And turnkey beowulf systems (built of COTS components) have been around
for many years now.  In fact, some list members (ahem;-) have built and
sold them.

So the new computer cluster (orien?), with a new CPU, is actually
FARTHER from COTS -- especially if the new CPU is designed only for use
in the cluster market.  Hopefully it isn't -- it's questionable as to
whether the cluster market can sustain a specialty CPU with so many COTS
alternatives that stay cheap because they are mass marketed.

Wal Mart sells compute nodes, too, if you want to use their cheap
systems for that purpose.
