Re: [condor-users] Condor and Hyperthreading

Adam,

This one is a "hard" one as it requires some ability to "plan" the future 
and to enforce some kind of a reservation to guarantee that a job that 
requires two hyperthreads does not starve ...  Doing it "right" forces all 
the challenges of multi-processor scheduling.
