yes, I would try something in that direction - but tbh I have not done 
it here ð
...but I would expect it to work "in principle" (fingers crossed...)


Thinking about it - maybe instead coming from the slot side, you could 
try to tweak the core count and increase it for Condor via something like

NUM_CPUS = $INT($(DETECTED_CPUS) * N)
MEMORY = $(DETECTED_MEMORY)
SLOT_WEIGHT = Cpus * (1.0/N)

(and then on the submitted side some quantization/re-scaling if necessary)

I would be curious how it works out :)

Cheers,
  Thomas
