This is the "traditional" config Heinz and Jeremy mentioned yesterday.
Since _LCG_ were never interested in SMP processing, there wasn't a
penalty in making the site look like a larger number of smaller single-CPU
boxes.
Of course other VOs now might want such resources, but a bigger risk is
that with pilot jobs frameworks, the pilot may look at the node it's
running on and request work packets suitable for the physical resources it
sees without taking into account that these will have to be shared with
others!
At least one part of biomed seems to be using boinc as a pilot job
framework for example (though they may have hacked their client of
course).
Thanks
