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.
