Got some working and fully functional C code for use under MPI. I want to take a look at running it under Fortran and Fortran 90 Is there an efficient C to Fortran converter out there anywhere ? Similar to the reverse: FreeBSD in particular provides a Fortran "compiler" named f77 that uses the freely-available Fortran to C converter f2c in combination with gcc to compile Fortran code.
