Dear OpenMPI users and developers, I'm using IBM Spectrum MPI 10.1.0 based
on OpenMPI, so I hope there are some MPI expert can help me to solve the
problem.
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

I noticed this on IBM's website too. Is this freely available? Up to now I was
always bounced back to their former Platform MPI when trying to download the
communit
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?

Hi Reuti, I think is it freely available. I posted also on IBM Spectrum
forum, I'm waiting some reply.

Hi John, about btl this is the output of ompi_info:
MCA btl: self (MCA v2.1.0, API v3.0.0, Component v10.1.0)
MCA btl: sm (MCA v2.1.0, API v3.0.0, Component v10.1.0)
MCA btl: tcp (MCA v2.1.0, API v3.0.0, Component v10.1.0)
MCA btl: vader (MCA v2.1.0, API v3.0.0, Component v10.1.0)
MCA fbtl: posix
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,
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

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
Hi Gilles, attached the requested info

I experiencing many different errors with openmpi version 2.1.1. I have
had a suspicion that this might be related to the way the servers were
connected and configured. Regardless below is a diagram of how the
server are configured.

Allan,
- on which node is mpirun invoked ?
- are you running from a batch manager ?
- is there any firewall running on your nodes ?
- how many interfaces are part of bond0 ?
the error is likely occuring when wiring-up mpirun/orted
what if you
mpirun -np 2 --hostfile nodes --mca oob_tcp_if
Hi Gilles, using your command:
[openpower:88536] mca: base: components_register: registering framework pml
components
[openpower:88536] mca: base: components_register: found loaded component
pami
[openpower:88536] mca: base: components_register: component pami register
function successful

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.
