Not to mention that the Debian Linux maintainers care about the stuff
they package and eat their own dog food.  Camm packages atlas and
other packages for Debian - I also owe him a debt of gratitude because
he took over LAM from me and packaged it properly so that it played
nicely with MPI :) There were long threads on this a few months back -
the bottom line is that (some of) the commercial distributions may
not include all the apps/libraries you need - so you'll end up hand
compiling/relying on someone's unofficial repository. (Some of) the
commercial distributions cost high licensing fees per node / have 
upgrade hell.

	BUT

If you need a turnkey solution to run out of the box from a major vendor
like IBM/HP or you have a need for something right now and your needs
are well defined and met by a pre-existing package, you need to go with
what the vendor will support.  As noted elsewhere in the thread, some
vendors may be more flexible.  I run a (very) toy cluster at work on
Debian because it's a prototype for someone else already running Debian. 
The big cluster coming soon to a building near me will be a commercial 
off the shelf product running a different Linux - because it's
supported. I can support Debian on any size of cluster they want - but
they don't want it dependent on one employee, which is sad but sort of
understandable :)
