You can pass data to the Apple frameworks directly from FORTRAN, just be
sure to observer the proper conventions for passing data from FORTRAN to C.
Most FORTRAN compiler manuals have a short section about this. It's really
pretty simple. And from what I remember, Apple's frameworks are pretty
robust in their ability to deal with data alignment and other issues
internally, so you don't have to.
There's an example on Apple's website that shows how to call a vecLib
function from FORTRAN (among other things), which ought to give a good
start:
http://developer.apple.com/hardware/ve/fortran.html
If you have the time to spare, you can build a simple test program to verify
the process, and then compile your bigger code.
