There is a known issue with OpenIB on PPC machines at the moment -- see:
https://svn.open-mpi.org/trac/ompi/ticket/23
<https://svn.open-mpi.org/trac/ompi/ticket/23>
A temporary workaround is to either use the SRQ or disable eager RDMA.
See the bug for the details of both of these options.

Subject: [OMPI users] pallas assistance ?
So I have 64bit ppc versions of openmpi, openib and the pallas
files (IMB_MP1 being the important one). ldd checks out okay and shows
nothing missing. However when I try to execute the pallas run it dies
like so:
[root@thing ompi]# /opt/ompi/bin/mpirun -np 2 -machinefile
machine.list ./IMB-MPI1
Signal:11 info.si_errno:0(Success) si_code:1(SEGV_MAPERR)

*** End of error message ***
are there any special things that need to be done with pallas,
open-ib, open-mpi ? Pallas compiled fine and linked okay with the needed
libraries. Currently machine.list is just localhost twice.
