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 -

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.

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 -

OMPI_COMM_WORLD_RANK can be used to get the MPI rank. For other environment

I wonder if this is something that needs to be tuned in the Infiniband

Thanks Jeff!
What is considered to be very large IB fabrics?
I assume that with just over 180 compute nodes,
our cluster does not fall into this category.

I'm using the latest of Open MPI compiled with debug turned on, and
