At least for the Power machines, that isn't conservative at all. -j1 is conservative. -j24 is not conservative on a machine with 20 CPUs (gcc112), or 32 CPUs (gcc135). The AIX (gcc119) jobs seem to run for over an hour on half the machine? That's no good :-( There are two important considerations for automated jobs. Are things set up so that your task cannot monopolise a system; and, are things set up so that your automated tasks do not hinder interactive work. Could you please work on making those two things true?
