Notes on C and Fortran

• C and Fortran bindings correspond closely

• In C:

  • mpi.h must be #included
  • MPI functions return error codes or MPI_SUCCESS

• In Fortran:

  • mpif.h must be included, or use MPI module (MPI-2)
  • All MPI calls are to subroutines, with a place for the return code in the last argument.

• C++ bindings, and Fortran-90 issues, are part of MPI-2.
