MVAPICH or OpenMPI with MDCE?

I've managed to get MDCE to work nicely with our installation of torque/mpich2-1.5, but I'd like to get it to use our IB network. So I've tried MVAPICH2-1.9 and OpenMPI-1.8.5. Neither seem to work. MVAPICH2 will execute, but I'm getting strange numerical errors. OpenMPI just seg faults. Can anyone verify that MDCE can work with IB and which MPI flavor is supported? BTW, mpich-3 also seg faults.

The following documentation describes how to use different MPI builds: http://www.mathworks.com/help/mdce/use-different-mpi-builds-on-unix-systems.html
Your build must be a shared library MPI, binary compatible with MPICH2-1.4.1p1 for R2013b and later.

Thanks for your answer. Since MPICH2 only works over ethernet, is it true that MDCE cannot use Infiniband?
