Hi, If this requirement is to be interpreted literally, then yes, the standard must define all datatypes in all languages. However, the example following this statement shows how an MPI_REAL is transformed into an equivalent C data type. Whether or not this is indeed MPI_REAL is not clear. It may well be an MPI_FLOAT. By the way, this example shows that MPI::Fint may be necessary: MPI_Fint is used here to pass Fortran datatype thru the C function boundary. Imagine a C++ function. There was a ticket #4 calling for removal of the MPI::Fint until it was redefined. Best regards.

You're right, I was not checking 2.1 implementations.
While 2.1 changelog item 2 does specifically mention those constants in all 3 languages, what about the other datatypes? (e.g., MPI_INT vs.
MPI_INTEGER, etc.?)
