knowing nothing about the jobs themselves, wouldn't it be possible to 
spawn all 10 jobs via a wrapper and start all 10 jobs via the wrapper 
after requiring, say, 10 CPU cores on a single machine?

That way, they would only launch on a single node and only if there was 
enough room in the (dynamic) slot.

Cheers
