If you were a worm, and especially in PF_ALG to play with crypto or
intensive tasks. You would lie and name yourself any of the above test

If and only if, you were a Intel Research employee that work on Intel C compiler
you'd be interested, and may require some omissions for time investments
with the best possible outcome being an article about it.
