[Wien] mpiexec_mpt

[Oleg Rubel]

Dear Luis,

It looks like the problem is not in Wien2k. I would recommend to make sure
that you can get a list of host names correctly before proceeding with
wien. There are slight difference between various mpi implementation in a
way of passing the host name list.
