This sounds like you are submitting a multi-core job without requesting a parallel environment (PE). It would be good to request for all parallel jobs a PE for the job where you specify 16 resp. 64 cores. Then this can't happen at all due to lack of free cores on node 1. A plain PE with the default values when you define a new one is sufficient, often it's named "smp" if it should stay on one node only for all slots. `man sge_pe` and submit: $ qsub -pe smp 64 job.sh (It's necessary to set the proper slot count [i.e. "64"] in the queue definition.) -- Reuti _______________________________________________ users mailing list [email protected] https://gridengine.org/mailman/listinfo/users
