Perhaps your sysadmin installed mpiexec with "ib" as the default
communication library, for use with MVAPICH (not 2).

Mvapich2, a version of mpich2 from Argonne, uses the PMI startup
mechanism as do all mpich2 implementations.  To tell mpiexec
about this, do:

    mpiexec --comm=pmi a.out

I'll add some text on the website about mvapich2.
