[OMPI users] QP error

[Nicolas Morey-Chaisemartin]

Hi,

I'm trying to run MPI applications (using openmpi 1.10 or 2.10) on a SUSE SLE12-SP3.
I have two server connected through IB and run a simple:
mpirun --prefix /usr/lib64/mpi/gcc/openmpi2/   --host 192.168.0.1,192.168.0.2 -npernode 1 --allow-run-as-root /usr/lib64/mpi/gcc/openmpi2/tests/IMB/IMB-MPI1

And I get this error:
mlx4: local QP operation err (QPN 000c09, WQE index 0, vendor syndrome 6c, opcode = 5e)


Note that this happens with all the MPI tests I've tried.
I've checked the setup with ib verbs testsuites and with mvapich2 MPI and both work fine.

I couldn't find any information on this. Has any one seen this before ?

Thanks

Nicolas
