18560[PanoToolsNG] Re: Fast Gigapixel Stitching on the Playstation 3
- Mar 8, 2008Sony cell's processor is a good processor but it should be more viewed as
a super GPU than a real CPU. But I'm a bit disapointed about this approach
from Mr Dersch ... Everyone here has a big graphic card that is far better
for any image
manipulation than any CPU will ever be. And stitching is just done in CPU.
I would not spend such developpement time on PS3 stitching and would
on using standard GPU to accelerate that. Interface to do that are now
stable ( CUDA for
example ), and every paper talking about GPU processing show factor from 10x
to 100x ...
Why spend so much time with a PS3 when we can do better with the GPU of the
( example : nvidia series 7000, 8000 are enough and technics are cross
plateform ... ).
Our internal experimentation about that shows that with GPU processing, a
10x factor is an
average of what you can get.
As a game programmer, I should be happy about this use of PS3, but in fact
It's perhaps also because of that history that I don't like Sony PS*. It's
really a nightmare to
code well. Before doing the game, you that to create the tools to do it : no
real dev workflow
are provided like remote debugger, etc. XBOX is far easier to code with.
Anyway, off topic.

Congratulations to Helmut Dersch. This is a stunning result!
If the application evolves beyond prototye, it is be incentive enough to
buy a PS3 and install Linux :-))))

not sure what I'm asking but briefly how does one make them useful for
things other then games.. What OS are they running..etc.. I apologise ahead
of time if this is to broad a question.. If so where can one gain a few
insights as to how to mak euse of thes elittle power houses..
>Sony actively helped to develop a Linux version that runs on the PS3, so
you can use the console just like a "normal computer".
The difference is: Current "next generation" game consoles (Xbox, PS3)
use specialized hardware, optimized for tasks which are common in
computer games: Media streaming, image manipulation, vector processing
etcetc... Coincidentally, this is also what you need for fast
image/panorama manipulation. The Cell CPU used in the PS3 is a derivate
of the IBM Power CPU (used in their servers and supercomputers):
