Perhaps there's interest in her talk at the GCC Summit.
Here's the underlying paper - sorry, the URL is quite long because it
comes from Google's cache:
http://www.google.com/search?q=cach...cc+summit&hl=nl
[ It turns up slightly garbled in my Mozilla (1.6) screen, but still
readable ]
Hope this is useful.

I am under the impression that you skip the last few steps - the
Intel compiler will inform you which of the loops it managed to
vectorize.
