In openib SVN we have a stripped down version of MVAPICH and only gen2
based devices (ch_gen2 and ch_gen2_multirail) are supported at this
SVN. To be able to use IPoIB, we
would encourage you to use the complete package available from the OSU
download page:

http://nowlab.cse.ohio-state.edu/projects/mpi-iba/download-mvapich/register.html

In the top directory is a make script for TCP, make.mvapich.tcp.
Please let us know if you
find any problems.

Thanks,
