Maybe you need to compile gmx without MPI (so that gmx tune_pme
is a serial executable), and a separate mdrun which naturally
needs to be MPI-enabled (the latter you pass via -mdrun argument).

What output is there on the command line?

Are you running on GPU nodes? Are all shared libraries needed by
mdrun actually found?
