On yet another test platform I see the following: $ mpirun -mca btl sm,self -np 1 examples/ring_c -------------------------------------------------------------------------- Open MPI was unable to obtain the username in order to create a path for its required temporary directories. This type of error is usually caused by a transient failure of network-based authentication services (e.g., LDAP or NIS failure due to network congestion), but can also be an indication of system misconfiguration.
Please consult your system administrator about these issues and try again. -------------------------------------------------------------------------- [biou2.rice.edu:30021] [[40214,0],0] ORTE_ERROR_LOG: Out of resource in file /home/phh1/SCRATCH/OMPI/openmpi-1.7-latest-linux-ppc32-xlc-11.1/openmpi-1.7.4rc2r30361/orte/util/session_dir.c at line 380 [biou2.rice.edu:30021] [[40214,0],0] ORTE_ERROR_LOG: Out of resource in file /home/phh1/SCRATCH/OMPI/openmpi-1.7-latest-linux-ppc32-xlc-11.1/openmpi-1.7.4rc2r30361/orte/mca/ess/hnp/ess_hnp_module.c at line 599 -------------------------------------------------------------------------- It looks like orte_init failed for some reason; your parallel process is likely to abort. There are many reasons that a parallel process can fail during orte_init; some of which are due to configuration or environment problems. This failure appears to be an internal failure; here's some additional information (which may only be relevant to an Open MPI developer): orte_session_dir failed --> Returned value Out of resource (-2) instead of ORTE_SUCCESS -------------------------------------------------------------------------- An "-np 2" run fails in the same manner. This is a production system and there is no problem with "whoami" or "id", leaving me doubting the explanation provided by the error message.
