Re: [condor-users] Condor and Hyperthreading


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.

Is there any way to do this on a per job basis, ie in the submit file. We
have a pool of dual xeons with 2GB per node giving 500 Mb per hyperthreded
processor, for most jobs this will be plenty memory but for other more
memory intensive jobs we'll need aroung 1Gb. So is there any way to
specify in the submit file that if 1Gb of RAM is required, use one
physical processor instead of the hyperthreaded ones?
