Thanks you so much for the support.

ps. One take away for everyone working with MPI.
Turn up the error logging or debug level.
then PAY ATTENTION to the error messages.
I have spent a LOT of my time doing just that - with OpenMPI and with Intel
MPI over Omnipath and other interconnects in the dim and distant past.

If I might interject here before lots of time is wasted. Spectrum MPI is an IBM
-product- and is not free. What you are likely running into is that their
license manager is blocking you from running, albeit without a really nice
error message. I’m sure that’s something they are working on.

hi Gabriele,
You can check some of the available options here -
https://www.ibm.com/support/knowledgecenter/en/SSZTET_10.1.0/smpi02/smpi02_interconnect.html
The "-pami_noib" option might be of help in this scenario. Alternatively,
on a single node, the vader BTL can also be used.
Regards

Gabriele,
can you
mpirun --mca btl_base_verbose 100 -np 2 ...
so we can figure out why nor sm nor vader is used ?

Gabriele,
as Gilles says if you are running within a single host system, you don not
need the pami layer.
Usually you would use the btls sm,selfthough I guess 'vader' is the
more up to date choice

Gabriele,
so it seems pml/pami assumes there is an infiniband card available (!)
i guess IBM folks will comment on that shortly.
meanwhile, you do not need pami since you are running on a single node
mpirun --mca pml ^pami ...
should do the trick

Infiniband is not used, there is a single node on this machine.

Gabriele, pleae run 'ibv_devinfo'
It looks to me like you may have the physical interface cards in these
systems, but you do not have the correct drivers or libraries loaded.
I have had similar messages when using Infiniband on x86 systems - which
did not have libibverbs installed.

Another thing Gabriele might want to check is whether the Spectrum MPI
launcher is being used. In Spectrum MPI, "mpirun" is a script that, among
other things, sets up the environment for Spectrum-specific libraries to be found.
In my experience, trying to "short circuit" the use of that script
Gabriele,
can you
ompi_info --all | grep pml
also, make sure there is nothing in your environment pointing to an other
Open MPI install
for example
ldd a.out
should only point to IBM libraries

Gilles

One very stupid question...what does 'ibv_devinfo' say when you run
it on the compute nodes?
ps. I know nothing about IBM MPI or pami but I think this is as you say
some simple library being missing etc.

Gabriele, as this is based on OpenMPI can you run ompi_info
then look for the btl which are available and the mtl which are available?
