Hi Ron,
We successfully run a mixture of WN hardware reaching from
8-core/8-slots via 8-core/16-slots w/ hyperthreading to
48-core/48-slots hosts at DESY-HH.
In our experience, it is crucial to intelligently distribute jobs over
the hardware in order to make optimal use of the resources.
You might be interested in our contribution to CHEP2012 containing the
poster and the paper:

Cheers
