you cannot run a binary that has been compiled with myrinet support on a 
node that does not have a working and configured myrinet card.

this is not an error from QE but from your (myrinet) MPI library.
before reporting MPI related problems, please first make
sure you can actually run MPI based executables _at all_.

cheers,
   axel.
