[Beowulf] SATA II - PXE+NFS - diskless compute nodes

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

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?
