The quickstart guide you are referring to is for MPICH2, not MVAPICH2.
The user guide and code base for MVAPICH2 is available from
http://mvapich.cse.ohio-state.edu. MVAPICH2 is based on MPICH2.  However,
it is designed and optimized for InfiniBand, RDMAoE, etc.

If you are experiencing any issues in running MPICH2, somebody on this
list can extend help to you.

If you are running your MPI application on an InfiniBand cluster and using
MVAPICH2 you can post your question to mvapich-discuss at cse.ohio-state.edu.

Hope this helps.
