How do I set up > scheduling policy to suspend scheduling serial jobs until higher-priority > parallel jobs are scheduled? You will need slot reservation for the parallel job. Mainly as a starting point: $ qconf -ssconf ... max_reservation 20 default_duration 8760:00:00 and submit the parallel jobs with "-R y". The best would be to supply all jobs (serial and parallel) with a sensible expected run time by "-l h_rt=…". This will both reserve slots for the large parallel job (which may reserve some slots which keep them idle until enough slots are collected) and backfilling, which will still allow serial (or smaller parallel jobs) to start on idle reserved cores if it's known for sure, that they will finish before the last necessary slot for the parallel job becomes free. - -- Reuti http://gridengine.org/pipermail/users/2012-July/004090.html -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iEYEARECAAYFAlm5mJ0ACgkQo/GbGkBRnRoGhQCeMU0RBHIVWLdeNddKse2sw/jd RNQAnj7PXXealFk0DYpmv53rca2MFqAM =5awF -----END PGP SIGNATURE----- _______________________________________________ SGE-discuss mailing list SGE-discuss@liv.ac.uk https://arc.liv.ac.uk/mailman/listinfo/sge-discuss
