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.

If this is Power 8 in LE mode, its most likely a libtool issue. You need
libtool >= 2.4.3, which has the LE patches, and need to run autogen.pl
again. I have an issue open for this -

Collecting MPI Profile information might help narrow down the issue. You
could use some of the tools mentioned here -

Hi Brian,
This problem was first reported by Paul H. Hargrove in the developer mailing
list. It is a bug in libtool and has been fixed in the latest release
(2.2.8). More details are available here -

Hi Eloi,
Sorry for the delay in response. I haven't read the entire email thread, but
do you have a test case which can reproduce this error? Without that it will
be difficult to nail down the cause. Just to clarify, I do not work for an
iwarp vendor. I can certainly try to reproduce it on an IB sy
Hi Gilbert,
Checksums are turned off by default. If you need checksums to be activated
add "-mca pml csum" to the mpirun command line.
Checksums are enabled only for inter-node communication. Intra-node
communication is typically over shared memory and hence checksum is disabled
for this case.

What interconnect are you using? Infiniband? Use "--without-memory-manager"
option while building ompi in order to disable ptmalloc.

You can find the template for a BTL in ompi/mca/btl/template (You will find
this on the subversion trunk). Copy and rename the folder/files. Use this as
a starting point.
For details on creating a new component (such as a new BTL) look here -
https://svn.open-mpi.org/trac/ompi/wiki/devel/CreateComp
OMPI_COMM_WORLD_RANK can be used to get the MPI rank. For other environment
variables -

__cxa_get_exception_ptr should be defined in libstdc++ shared library.

This probably got fixed in https://svn.open-mpi.org/trac/ompi/ticket/2386
Can you try 1.4.2, the fix should be in there.

You could try statically linking the Intel-provided libraries. Use

fs1 is selecting the "cm" PML whereas other nodes are selecting the
"ob1" PML component. You can force ob1 to be used via "--mca pml ob1"
What kind of hardware/NIC does fs1 have?

Can you try with Open MPI 1.2.6. It has a parameter to disable early
