ubuntu + oscar clusters?

[calcpage at aol.com]

I am wondering if anyone out there has experience setting up an OSCAR 
cluster over Ubuntu?  See 
http://svn.oscar.openclustergroup.org/trac/oscar

OSCAR is a clustering bundle built around openMPI that can be installed 
on top of your current distro.  I haven't tried it, but it looks 
interesting.  I recently tried using 
http://www.rocksclusters.org/wordpress which automates the install 
process by taking over the whole partition table on each node of the 
cluster installing some sort of paired down version of RHEL like 
CentOS.  Rocks has a lot of other restrictions like making eth0 private 
and eth1 public.  I just can't get into it!

So, now that I have installed Ubuntu 10.04 64bit on 25 dual-core AMD 
Athons, I thought I could try out OSCAR instead.  I'd like to get an 
hdd installed cluster that acts something like the pelicanHPC CD which 
uses openMPI+MPITB+Octave to write parallel code in Octave (like 
MATLAB).
