I do not think Open MPI explicitly asks SLURM which cores have been
assigned on each node.
So if you are planning to run multiple jobs on the same node, your best bet
is probably to have SLURM

for this kind of BS. However, I have a much lower threshold for your
gross mischaracterization of the Open MPI community, its values, and how
the work gets done.

Daniel,
the test works in my environment (1 node, 32 GB memory) with all the
mentioned parameters.
Did you check the memory usage on your nodes and made sure the oom
killer did not shoot any process?

Vineet,
probably *not* what you expect, but I guess you can try
$ cat host-file
host1 slots=3
host2 slots=3
host3 slots=3
$ mpirun -hostfile host-file -np 2 ./EXE1 : -np 1 ./EXE2 : -np 2
./EXE1 : -np 1 ./EXE2 : -np 2 ./EXE1 : -np 1 ./EXE2

Hi Patrick,
Glad to hear you are now able to move forward.
Please keep in mind this is not a fix but a temporary workaround.
At first glance, I did not spot any issue in the current code.
It turned out that the memory leak disappeared when doing things differently

) but not with the v3.1.x branch
(this suggests there could be an error in the latest Open MPI ... or
in the code)
- the attached patch seems to have a positive effect, can you please
give it a try?

Patrick,
I'm afraid there is no simple way to check this. The main reason being
that OMPI use handles for MPI objects, and these handles are not
tracked by the library
will be very much appreciated in order to improve ompio

Patrick,
In recent Open MPI releases, the default component for MPI-IO is ompio
(and no more romio)
unless the file is on a Lustre filesystem.
You can force romio with
mpirun --mca io ^ompio ...

Dean,
That typically occurs when some nodes have multiple interfaces, and
several nodes have a similar IP on a private/unused interface.
I suggest you explicitly restrict the interface Open MPI should be using.
For example, you can
mpirun --mca btl_tcp_if_include eth0 ...

but
you should first ask yourself if you really want to run 12 MPI tasks
on your machine.

Alan,
thanks for the report, I addressed this issue in
https://github.com/open-mpi/ompi/pull/8116
As a temporary workaround, you can apply the attached patch.
FWIW, f18 (shipped with LLVM 11.0.0) is still in development and uses
gfortran under the hood.

If a firewall is running on your nodes, I suggest you disable it and try again
