If the inner loops are about the same size for each pass of the 
outer loop, you can just simply parallel on the outer loop and 
get the same benefit.

Even if they aren't equal, you'll get decent benefit from 
parallel on the outer one alone, but not as good since the work 
won't be balanced.

Still, that's what I'd try.
