Subject: Re: [osg-users] osgPPU CUDA Example - slower than expected?
Hi,
I don't have any other suggestions than to use a GL debugger to make
sure nothing is going to CPU or to try the new CUDA functions in osgPPU
or your own code. I remember something in the GL to CUDA stuff
Hi Thorsten,
the problem which you experience is because of lacking direct memory mapping
between OpenGL and CUDA memory. Even if CUDA (at least it was in version 2 so)
supports GPU-GPU memory mapping, whenever you access to OpenGL textures there
is a full memory copy performed.
I am not

Thanks for the answers. Actually I also know that there are new
interoperability features in CUDA 3, but I didn't have the time to check
them out yet, though if I find the time for it, I will let you know
about the results :)

Hi,
as I explained in some other mail to this list, I am currently working
on a graph based image processing framework using CUDA. Basically, this
is independent from OSG, but I am using OSG for my example application :-)
For my first implemented postprocessing algorithm I need color and
By the way: There are two CUDA-capable devices in the computer, but I
have tried using the rendering device as well as the CUDA-only device
- no difference!

Ok..I correct this: There is a difference of ~1 frame ;) ...now I will
stop replying to my own messages :D
