Did you look at the VAST PDF here?

I've looked at that many times and its not really helped me.
Any real-world examples? Any before/after code snippets?

Thanks!

Anyone have any Fortran examples using the velocity-engine (vector processor) to improve performance?

The developer documentation has a small code sample from Ian.
http://developer.apple.com/hardware/ve/fortran.html

the code is here:
http://developer.apple.com/hardware/ve/downloads/fortran_sample.tar.gz

information about optimizing with VAST (including a small optimized Fortran source) is here:
http://hpc.sourceforge.net/index2.php

and finally, the VAST user guide for Altivec & Fortran has a lot of good general info, even if you aren't planning on using VAST.
