What do you mean by "Fortran 77 codes"? There are codes that are written in fixed source form and others in free source form. If by F77 you mean fixed source form, then that should be accommodated. Otherwise, old codes that were written in the before ~ 1993 are still Fortran programs and should compile with modern compilers for today's incarnation of standard Fortran. Apart from supporting fixed source form, what retrofit is necessary? Cheers, Bill Craig Rasmussen wrote:
Jeff raised an interesting question with me. Should new features that are being considered for MPI-3 be retrofitted if possible for Fortran 77 codes? Some users might say yes as they never intend to use modern Fortran features. On the other hand, F77 is over 30 years old and so perhaps we should move on and not put support (money) into adding new features.
The new Fortran MPI-3 bindings will allow users to link to codes using F77 bindings so if users want new bindings they only have to use MPI3 locally.
