Hi all,
we are facing a serious problem with OpenMPI (4.0.2) that we have
deployed on a cluster. We do not manage this large cluster and the names
of the nodes do not agree with Internet standards for protocols: they
contain a "_" (underscore) character.
So OpenMPI complains about this and d
Patrick,
I am not sure Open MPI can do that out of the box.
Maybe hacking pmix_net_get_hostname() in
opal/mca/pmix/pmix3x/pmix/src/util/net.c
can do the trick.
Cheers,
Gilles

Patrick,
you will likely also need to apply the same hack to opal_net_get_hostname()
in opal/util/net.c
Cheers,

Hi Gilles and Jeff,
@Gilles I will have a look at these files, thanks.
@Jeff this is the error message (screen dump attached) and of course the
nodes names do not agree with the standard.

This error seems to be initiated from the PMIX regex framework. Not sure
exactly which one is used, but a good starting point is in one of the files
in 3rd-party/openpmix/src/mca/preg/. Look for the generate_node_regex
function in the different components, one of them is raising the error.

Ah; this is a slightly different error than what Gilles was guessing from your
prior description. This is what you're running in to:
https://github.com/open-mpi/ompi/blob/v4.0.x/orte/mca/regx/fwd/regx_fwd.c#L130-L134
Try running with:
mpirun --mca regex naive ...
Specifically: the "fwd" regex
