Also depends on external criteria too. For instance we have to try to balance usage between the 8 different universities who are partners in VPAC, and they have hugely varying usage profiles. So we are not given the luxury of just letting the scheduler completely reorder queued jobs for backfill and we have to impose limits on number of CPUs per user and institute as well as using fair share to count in prioritising jobs. We could get a higher utilisation if we gave carte blanche to the handful of users who queue hundreds of single CPU jobs each and had them backfill every gap, but then we'd get hammered by the members on the board (quite rightly) for not giving others a look in. :-) cheers, Chris -- Christopher Samuel - (03) 9925 4751 - Systems Manager The Victorian Partnership for Advanced Computing P.O.
