PS:


I ran your example on my computer (AMD XP-3200+, 512mb) with my array
language and find that to execute your expression for eight arrays (i1
through i8) array with 1 million elements takes about 400 ms. This
used double floats, so single floats should run correspondingly
faster, at least from moving half of the memory around.
