[Condor-users] How to avoid matching lower ranked jobs to machines

[Horvátth Szabolcs <szabolcs@xxxxxxxxxxxxx>]

Hi,

I see quite a lot of jobs matched to free machines and then get vacated at the next negotiation cycle in favor of a higher machine-ranked job (that was also in the queue when the first negotiation happened).
I'd like to minimize this by making the negotiator respect the machine rank preferences and avoid a lower ranked job matching before a higher ranked one, but I'm not sure which attribute(s) to use.
I was looking at NEGOTIATOR_PRE_JOB_RANK and NEGOTIATOR_POST_JOB_RANK but I don't know how to use them for this purpose.

Cheers,
Szabolcs
