For parallel jobs you need to configure a (or some) so called PE (Parallel Environment). Purpose of this is, to make preparations for the parallel jobs like rearranging the list of granted slots, prepare shared directories between the nodes,... These PEs were of higher importance in former times, when parallel libraries were not programmed to integrate automatically in SGE for a tight integration. Your submissions could read: qsub -pe smp 4 myjob # allocation_rule $peslots, control_slaves true qsub -pe orte 16 myjob # allovation_rule $round_robin, control_slaves tue where smp resp. orte is the chosen parallel environment for OpenMP resp. Open MPI. Its settings are explained in `man sge_pe`, the "-pe" parameter to in the submission command in `man qsub`. -- Reuti _______________________________________________ users mailing list users@gridengine.org https://gridengine.org/mailman/listinfo/users
