[HTCondor-users] Setting JOB_RENICE_INCREMENT to be greater than 19


On our cluster we run sshd with niceness of -20 to make interactive maintenance of overloaded worker nodes less painful. It seems to me it's not possible possible to get Condor to run jobs with niceness 19 if the shell that started Condor has negative niceness. Is this correct?

According to documentation, Condor auto-decreases provided JOB_RENICE_INCREMENT value to 19. This means that if condor is started by a -20 niceness shell, jobs will have -1 niceness, which is better than what system processes have by default.

Unless I am missing something, it would be nice to be able to configure jobs' absolute niceness value, or at least allow JOB_RENICE_INCREMENT to be over 19.
