Getting it out is my main priority for 2010.

Now compiling with -msse2 is enough to trigger simdisation. If you use
nt2 container it does everythign already (alignment+padding). If you
happen to pass some naked pointer, we have a split strategy: we ofund
the first aligned element, the last one and apply SSE on these. The pre
and prologue are done in a scalar way. That's the best we can do. To
prevent further pollution of this ML, I direct you to

No problem :) Soon, the git will contain the bare container system based
on proto with a selection of usable functions. Tests and deploiement
will be very welcome.

We have a post-doc on that already. Current prototype for openCL based
nt2 is on the par with comemrcial product liek Rapidmind.
