/** \file
  \brief MPI bindings for thread_mpi/tmpi.h

  This file contains only macros and redefinitions to expose the standard 
  MPI API with thread_mpi calls. 
  
  This is different from the API exposed through thread_mpi/tmpi.h, which 
  uses names like \a tMPI_Send() instead of \a MPI_Send()

  \sa thread_mpi/tmpi.h for documentation of the available data types and 
      functions
  \sa http://www.mpi-forum.org/docs/docs.html for MPI documentation.
