GPUs are, but do they support CUDA or similar*?
Of the three machines here that are on, one does (GeForce 8800GTS) one
doesn't (GeForce FX 5200) and one I don't know (a fairly recent HP laptop).
*) Actually the real question is: will they when you have finished your
port.

I don't think so. I really think you should not have asked that. Whether
jokingly or not. I also know that I would feel uncomfortable when I
would have been in his place, so that is why I apologized for possibly
having caused that (whether he would have felt the same way is immaterial).

Apology accepted, though not needed, andrel. I have heard much worse
then 'sweetie' and 'dear' in various MMOs. You learn more about a person
by the words they choose to address others by, and the same verbal
jujitsu works.

they will once code is complete. By the time povray 3.7 was started,
the thought of running raytracing on GPU was a distant dream. Looks
like hardware evolves far faster than software. You can certainly tell
that by how slow paradigms change and new languages with radically new
ideas flourish (motivated by hardware changes anyway)...

The first is the only one that counts, since it's the most recent (and
fairly old already BTW). Laptops always use yesterday's technology.
We shouldn't have to wait for the iPhone to have a proper GPU to begin
any such coding...

I hope you have learned that I'm a clown by heart. I enjoy making

Ah, still young and naive. I have seen a lot of promising technology and
software discontinued after a few years. I think it is highly like (
>70% ) that this particular type of GPU programming will be obsolete in
5 years time. Most probably replaced by an API where you don't know if
software is running on a GPU or not, if I can have a guess. Because of
backwards compatibility you know.

The laptop is the newest by far. The reason I have that 8800 is that I
don't do much things that require a fast graphics card (mainly signal
processing and some POV if I get a chance. Blender is the only thing
that might benefit from a better card.). I decided not to spend money on
that when I bought the machine and wait until I really needed one.
Assuming that by then I could get more performance for less money.

Ok, be my guest. I'll wait and see what you come up with.

Keep working on it, it does not come through on the internet, at least
not for me.

I look at heavyweights in the industry at large and they seem to think
differently. Either you are right and they will all be broke by
investing on a fad or you are

Like heterogeneous multiprocessing with OpenCL? Agreed.

It has a newer card? I don't like laptops precisely because you pay too
much to use old tech (that are finally miniaturized enough to fit and
consume less power).

yes, keep waiting.

sadly, my humorous side is often a victim of my troll side and thus
don't get as much recognition, specially when people are fed up already.

Right, so, which should be supported? CUDA, Stream, OpenCL, or do we
just do things with shaders and hack tricks in DirectX and OpenGL? Do we
go lower than that, skip the OS, and make POV-Ray something that runs at
a very low level, accessing the hardware in assembly just to get every
bit of speed and capability from the architectures? Support your answer
with examples of benefits and potential problems that will be faced
along the development path. Discuss the impact that future GPU
capabilities, such as shorter buses, integration into the CPU, and
branching, will offer.
