First of, we haven't released 0.9.11 yet. However, the ibverbs parcelport was disabled for 0.9.10 because it was not properly maintained and contained some severe bugs. We are working on a new version of an infiniband based parcelport which should be ready soon. In the mean time, using the MPI based parcelport is your best shot.
