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

[Vladimir Brik <vladimir.brik@xxxxxxxxxxxxxxxx>]

Hello.

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.
