It works but honestly I can't say it is 'production'. If you are
interested in the 'roll' it is located at:
http://www.osgdc.org/project/kusu/wiki/RocksRoll
We tried it with Rocks 4.1 (not Rocks 4.2) and Platform OCS
(http://my.platform.com/products/platform-ocs)
The roll takes the existing rocks repository on the frontend and builds
a vnfs image out of it for the compute nodes. It also turns off the
standard rocks DHCP and PXE changes and replaces them with warewulf...it
isn't pretty but it does work.
Regards,
Bill.

Hi Bill,
I will try to email them and let everyone know what they have to say.
How did the Rocks -> warewulf conversion go?
Thanks,
Eric

Hi Eric,
You may want to send the Perceus guys an email and ask them how hard
it
is to replace cAos Linux with RHEL or CentOS. I don't believe it
should
be that hard for them to do....we modified Warewulf to install on top
of
a stock Rocks cluster effectively turning a Rocks cluster into a
Warewulf cluster - and the cluster was running RHEL....so it is
possible.
Regards,
Bill.

Scyld CW4 is based on RHEL4 and also supported on Centos 4. That does
not give you different
operating systems though, just flexible deployment of RHEL4 based HPC
compute nodes.
Note that we had to reimplement the PXE boot part to allow reasonable
scaling.

Not to diverge this conversation, but has anyone had any experience
using this pxe boot / nfs model with a rhel variant? I have been
wanting to do a nfs root or ramdisk model for some-time but our
software
stack requires a rhel base so Scyld and Perceus most likely will not
work (although I am still looking into both of them to make sure)
Thanks for any help,
Eric Shook

I agree with what Joe says about a few hundred nodes being the time
you would start to look closer at this approach.
I have started to explore the possibility of using this technology
because I would really like to see us with the ability to change OSs
and
OS Personalities as needed. The question I have is with 2000+ compute
nodes what kind of infrastructure do I need to support this?
