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.
