Re: [HTCondor-users] System setpriority()

[William Strecker-Kellogg <willsk@xxxxxxx>]

Hi Brian,

It looks you are interested in JOB_RENICE_INCREMENT: 

http://research.cs.wisc.edu/htcondor/manual/v8.4/3_3Configuration.html#25185

This is a machine-owner-policy totally independent from the priority in condor 
jobs. Job-priority only affects the order that your *own* jobs are considered 
in, it can't even override cross-user priority factors unless they aren't 
configured.

Thanks,
Will
