Subject: [OMPI devel] 1.7.4rc: yet another launch failure
From: Paul Hargrove (phhargrove_at_[hidden])
Date: 2014-01-22 22:02:09


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.

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.

[phh1_at_biou2 ~]$ whoami
phh1
[phh1_at_biou2 ~]$ id
uid=44154(phh1) gid=2016(hpc)
groups=2016(hpc),3803(hpcusers),3805(sshgw),3808(biou)

The "ompi_info --all" output is attached.
Please let me know what additional info is needed.
