Hi Ralph, this problem is not fixed completely by today's latest ticket #4383, I guess ...
https://svn.open-mpi.org/trac/ompi/ticket/4383 For example, in case of returing with ORTE_ERR_SILENT from the line 514 in rmaps_rr_mapper.c file, the problem still occurs. I executed the job under the unmanaged condition - rsh without torque: [mishima@manage openmpi-1.7.5rc2]$ mpirun -np 6 -host node05,node06 -nooversubscribe ~/mis/openmpi/demos/myprog -------------------------------------------------------------------------- There are not enough slots available in the system to satisfy the 6 slots that were requested by the application: /home/mishima/mis/openmpi/demos/myprog Either request fewer slots for your application, or make more slots available for use. -------------------------------------------------------------------------- Abort is in progress...hit ctrl-c again within 5 seconds to forcibly terminate Abort is in progress...hit ctrl-c again within 5 seconds to forcibly terminate ..... rmaps_rr_mapper.c: 509 /* quick check to see if we can map all the procs */ 510 if (num_slots < (app->num_procs * orte_rmaps_base.cpus_per_rank)) { 511 if (ORTE_MAPPING_NO_OVERSUBSCRIBE & ORTE_GET_MAPPING_DIRECTIVE(jdata->map->mapping)) { 512 orte_show_help("help-orte-rmaps-base.txt", "orte-rmaps-base:alloc-error", 513 true, app->num_procs, app->app); 514 return ORTE_ERR_SILENT; 515 } Tetsuya
