Hi together,
i think about to port my algorithm from SSE to AVX - but the AVX abilities for integer arithmetic and logical manipulation are poor...
So i think the overhead to emulate this instructions for full 256-bit support isn't worth the trouble.
Or have someone of you other experiences?!?
Hi phaap,
I think AVX gives a lot of new opportunities and it's worth to migrate your SSE code to AVX.

That's not quite right. According to the manuals (Intel or AMD) for every SSE instruction you've an appropriate AVX instruction (for example: MULPS and VMULPS). Of course, a lot of AVX integer instructions have only a 128 bit encoding, while others have both. All things considered, AVX gives a great performance boost. You could check the following 64 bit example: http://masm32.com/board/index.php?topic=795.0 (http://masm32.com/board/index.php?topic=795.0) On the other hand: AVX2 will need some time.

I was not aware that we can port SSE to AVX or switching from one to the other. So this is how I am going get new information here and I am glad I can learn so much.
Hi noellerichmond,
first things first: Welcome to the forum.

Sure, we can, if the AVX instruction set is available (Sandy Bridge, Ivy Bridge, Bulldozer). For more information, please check out that (http://masm32.com/board/index.php?topic=795.0) or that (http://masm32.com/board/index.php?topic=1597.0) thread.

not everything will port back and forth smoothly
rather than thinking in terms of using "SSE or AVX", you might consider how they compliment each other
noellerichmond,
Answer us this question, does your membership in this forum have anything to do with assembler programming ? I notice that you have advertising for a non-programming activity as your signature which has nothing to do with this forum at all.
We do not allow any advertising at all and we do enforce it to keep a mountain of crap out of the forum.
Please let us know quickly or we will have to remove your post and membership.
Bravo hutch :eusa_clap:
I spotted that instantly and wanted to worn about it
but I waited to see if someone else will do it instead
I was surprised that Gunther & dedndave did not react
however, it is nice to see some female interested in assembly programming
even if just pretending :greenclp:

generally, i'd agree with you guys
i think you are reading too much into it, in this case - lol
maybe not
it is odd that she has a fully set-up profile on first post :P

Yeah, that's right. Let's wait if there is a second sign of life 8)
well - there are certainly a number of ways to contact her - lol
she set up an e-mail, AOL IM, and yahoo IM :lol:
If Jochen and habran are right, and that could be, and our message boxes are full of spam, Hutch needs only a few mouse clicks and the thing is over. So let's see what happens in the future.

the boy and girl question isn't so decisive. But in general, search engine optimization (SEO) isn't an easy task and I've doubts that a few mouse clicks more will bring forward the employer's site.
Gunther
Is there some easy way to get the search engines to ignore such links?

Good catch Tedd.

Hey Ted, are you sure that you are not reincarnation of Sherlock :t
that's a neat trick, Tedd - lol

Well done, Tedd. :t The rest should be very easy.
