Hi Ralph,
the problem occurs when you add --host with a different machine. Without
--host or with "--host <same machine>" everything works well.

I’ll remove the debug, but it looks like this was already fixed.

Hi,
I've installed openmpi-v3.0.0 on my "SUSE Linux Enterprise Server 12.3
(x86_64)" with gcc-6.4.0. Today I discovered that I get an error for --map-by
that I don't
get with older versions.

The request to bind processes could not be completed due to
an internal error - the locale of the following process was
not set by the mapper code:
Process: [[57386,1],3]
Please contact the OMPI developers for assistance. Meantime,
you will still be able to run your application without binding
by specifying "--bind-to none" on your command line.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
ORTE has lost communication with a remote daemon.
HNP daemon : [[57386,0],0] on node loki
Remote daemon: [[57386,0],2] on node pc03
This is usually due to either a failure of the TCP network
connection to the node, or possibly an internal failure of
the daemon itself. We cannot recover from this failure, and
therefore will terminate the job.

I would be grateful, if somebody can fix the problem. Do you need anything
else? Thank you very much for any help in advance.
Kind regards
