Doing a full install will give you the latest errata as of the time the
CD was done, it will also do the entire install easily for you. As for
what it sets up, off the top of my head the only files I can remember it
doing special are /etc/beowulf/config and /etc/exports (If you want to
know for certain, let me know and I will double-check my anaconda
patches for you) Scyld Beowulf uses beoserv to give nodes their IPs
over RARP instead of dhcp, so dhcp does no need to be setup, and we also
use beonss which provides a hostname lookup facility that ties directly
into BProc and bypasses DNS (however, programs such as ping will work
like you want just by having the beonss package installed).
Other than the new errata and those two files there is nothing extra you
get from doing the full install off of the CD except for the ease of
having the installer just do it all for you.
I must note, my above answer was given as if you were installing over
RH6.2 I do *NOT* recommend installing the binary rpms from a
RHL6.2-based Scyld Beowulf over a RHL7.2 system. This is by no means a
supported method. I don't know if anything will or won't break in doing
it, but I would assume that something will considering how much has
changed between RHL6.2 and RHL7.2 If you really want to try, you're
free to try, but if you want something right now, I'd suggesting going
to the RHL6.2 based setup.

Yes! Our most recent version is 27z-9 (starting with -8 the first
character was used to distinguish architectures and basic/profesional,
but the general version is referrned to without it.. ie 27z-8 or 27z-9
as opposed to 27az-8, 27bz-8, 27cz-8, etc) As far as I know, there are
no available iso images for Scyld Beowulf (the bandwidth to serve them
is expensive). I recommend contacting sales at scyld.com and ordering the
most recent version.

Um.. erm.. there isn't one :) ftp://ftp.scyld.com/pub/beowulf/ is where
we keep our rpms. We only have binary rpms up for 27bz-7 and 27bz-6.
For the newer versions, we only have the original srpms and the binary
and srpms for any updates we did. Oh, and remember, don't mix RHL7.2
with our RHL6.2 based product, that's just a bad combination if you ask
