well, the site I was referring to didn't run LCG - they have installed
NorduGrid's m/w (which only needs the front-end) and ran ATLAS jobs on
the worker nodes via chroot. The cluster is in Ljubljana, the manager is
certain Andrej Filipcic, and he might be able to help you. Please let me
know if you are still interested.
Cheers,
Oxana
PS: FWIW, NorduGrid also supports SGE, so your main cluster can easily
contribute to ATLAS Data Challenges via that m/w without much hassle,
like e.g. the cluster in Umea did. But beware of the overfilled Storage
Elements :-)
