i wonder which are the fastest math functions out there... to all asm hackers/gurus whatever: i''d love to see your fastest implementations of dot, acos, rsq etc... and their number of cycles ;-)

I agree; I would love to see some good code for different math functions. In the mean time, check out Paul Hsieh's page for a few good routines: http://www.azillionmonkeys.com/qed/tech.shtml.

Fastest implementation of... dot?

You can''t exactly optimise the dot product. It''s not even that slow to begin with, anyway...
