I dunno. I haven't looked at what's going on with FORTRAN in a meaningful way in years. It might largely fall on how algorithms designed to exploit long-obsolete vector processors have been adapted to work on modern, highly parallelized supercomputer networks, with powerful but conventional individual nodes separated by really slow networks.
