Maybe I'm not on the right track, but do you speak about
multiprocessor machines?
Isn't it the job of the system kernel to provide parallelism
to your application?
Why should the user do coding low-level hardware-stuff in the
user-space programs?  This does not make sense to me.

The OS should be able to hide special treatment of multiprocessor
architectures or CPU-internal modifications from the user and
do all this parallelism stuff transparently.

On Linux for example: don't forget to compile your kernel
with SMP-options and so on.

So, if I've overseen something, let me know it.
