could you check that the install location of the library is the same

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
e legacy openib btl?
If the former, is it built with multi threading support?
If the latter, I suggest you give UCX - built with multi threading
support - a try and see how it goes
Cheers,

Hi all,
I ran many tests today. I saw that an older 4.0.2 version of OpenMPI
packaged with Nix was running using openib. So I add the --with-verbs
option to setup this module.
That I can see now is that:
mpirun -hostfile $OAR_NODEFILE *--mca mtl psm -mca btl_openib_allow_ib
true*
- the
07 but expect 4007
but it fails too.

Solved.
Strange conflict (not explained) after several compilation test of OpenMPI with
gcc7. Solved by removing the destination directory before any new "make install"
command.

You can override this protection by adding the "overload-allowed"
