Hi Andrew,<br>
<br>
Yes, the fortran and c++ bindings are just wrappers over the C bindings. The C binding implements the functionality directly.</blockquote><div><br>Are they wrappers of MPI_XXX() or PMPI_XXX()?<br><br>Best<br><br>Andrew <br>

Hello, everyone,<br>
<br>
I am working with MPICH2 on Windows platfrom. The fortran MIP application is linked to fmpich.lib, and fmpich2.dll is loaded in runtime, which in turn loads mipch2mpi.dll.<br>
mpich2mpi.dll contains all MPI APIs which exported C interface. What I want to know is: what is the 'underlying' relation between fmpich2.dll and mpich2mip.dll? Do all<br>
Fortran MPI calls are converted to c bindings in mpich2mpi.dll? For example, does MPI_BCAST() in fmich2.dll directly calls MPI_Bcast() in mpich2mpi.dll? Is MPI_BCAST() just a stub while MPI_Bcast() do the real job?<br>
<br>
Thanks<br>
<br>
Andrew<br>
