Hello,
In spite of the delay, I was not able to solve my problem. Thanks to
Joseph and Prentice for their interesting suggestions.
I uninstalled AppAmor (SElinux is not installed ) as suggested by
Prentice but there were no changes, mpirun sttill hangs.
The result of gdb stack trace is the

Hi, in context of the PRRTE Distributed Virtual Machine, is there a way
to tell the task mapper inside prun to not share a node across separate
prun jobs?
For example, inside a resource allocation from Cobalt/ALPS: 2 nodes with
64 cores each:
prte --daemonize

IIRC, the correct syntax is:

prun -host +e:2 ...
I haven't tested that in a bit, so please let us know if it works or not so we
can fix it if necessary.

Hello
The hwloc/X11 stuff is caused by OpenMPI using a hwloc that was built
with the GL backend enabled (in your case, it's because package
libhwloc-plugins is installed). That backend is used for querying the
locality of X11 displays running on NVIDIA GPUs (using libxnvctrl). Does
