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
(if it does not work, can run and post the logs)
mpirun --mca pml ^pami --mca pml_base_verbose 100 ...
Cheers,
Gilles

Hi John,
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.

No components were able to be opened in the pml framework.
This typically means that either no components of this type were
installed, or none of the installed componnets can be loaded.
Sometimes this means that shared libraries required by these
components are unable to be found/loaded.

Gabriele,
pml/pami is here, at least according to ompi_info
can you update your mpirun command like this
mpirun --mca pml_base_verbose 100 ..
and post the output ?
Cheers,
Gilles

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
Cheers,
Gilles

Dear OpenMPI users and developers, I'm using

some MPI expert

When I run a simple Hello World MPI program, I
get the follow
error message:
A requested component was not found, or was
unable to be
opened. This
means that this component is either not
installed or is unable
to be
used on your system (e.g., sometimes this

Open MPI stopped checking at the first

It looks like MPI_INIT failed for some reason;
your parallel
process is
likely to abort. There are many reasons that a
parallel
process can
fail during MPI_INIT; some of which are due to
configuration
or environment
problems. This failure appears to be an
internal failure;
here's some
additional information (which may only be
relevant to an Open MPI
developer):
mca_pml_base_open() failed
--> Returned "Not found" (-13) instead of
"Success" (0)
--------------------------------------------------------------------------
*** An error occurred in MPI_Init
*** on a NULL communicator
*** MPI_ERRORS_ARE_FATAL (processes in this
communicator will
now abort,
*** and potentially your MPI job)
My sysadmin used official IBM Spectrum
packages to install
MPI, so It's quite strange that there are some
components
missing (pami). Any help? Thanks
