One of the reasons is that the MPI C routines return a function value and most of the Fortran bindings are subroutines without a return value. The language you refer to is a requirement on the implementer as to what the name of the wrapper routine is.</div><div><br></div><div>For example, if the user calls MPI_Isend and uses the MPI_F08 module, then the wrapper routine shall (must) be called MPI_Isend_f08. Another requirement we have placed on implementors is that the wrapper name can't be hidden within a module so that Fortran module name mangling won't be done for the MPI_Isend_f08 routine.</div><br><div apple-content-edited="true">
