Seems like connected problem: I can't use rankfile with app, even after all those fixes ( working with trunk 1.4a1r21657). This is my case :
$cat rankfile rank 0=+n1 slot=0 rank 1=+n0 slot=0 $cat appfile -np 1 hostname -np 1 hostname $mpirun -np 2 -H witch1,witch2 -rf rankfile -app appfile -------------------------------------------------------------------------- Rankfile claimed host +n1 by index that is bigger than number of allocated hosts. -------------------------------------------------------------------------- [dellix7:13414] [[10851,0],0] ORTE_ERROR_LOG: Bad parameter in file ../../../../../orte/mca/rmaps/rank_file/rmaps_rank_file.c at line 422 [dellix7:13414] [[10851,0],0] ORTE_ERROR_LOG: Bad parameter in file ../../../../orte/mca/rmaps/base/rmaps_base_map_job.c at line 85 [dellix7:13414] [[10851,0],0] ORTE_ERROR_LOG: Bad parameter in file ../../../../orte/mca/plm/base/plm_base_launch_support.c at line 103 [dellix7:13414] [[10851,0],0] ORTE_ERROR_LOG: Bad parameter in file ../../../../../orte/mca/plm/rsh/plm_rsh_module.c at line 1001 The problem is, that rankfile mapper tries to find an appropriate host in the partial ( and not full ) hostlist. Any suggestions how to fix it? Thanks Lenny.
