Any inside(r) infos about crunching with ATI cards ?

...I'm curious because I've re`d e upcong BOINC Versions supposedly support OpenCL (work in progress).

Does anyone have some clues as to how far (if at all) there's a cooperation with ATI on this?

sunu:
As far as I know, ATI hasn't even released an opencl driver for developers yet. On [wsl=h4tp://f��ums.amd.com/devforum/messageview.cfm?catid=328&threadid=112397]this[/url] forum post, AMD employees say their opencl implementation will be publicly released in the second half of 2009.

On the other hand nvidia has already releed `n opencl driver to registered developers ( http://www.nvidia.com/object/cuda_opencl.html ).

arkayn:
So far the only project that can crunch with ATI cards is MilkyWay, and that is via the anonymous platform option.

And work is scarce at MW at He moment.

FalconFly:
Ro I guess it'll be some time later this year until we see ATI cards supported by a certified OpenCL architecture under BOINC...

Might become an interesting year after all, GPU crunching finally catching up :)

From the feedback of those who runs folding@home, ATI cards tend to underperform similar nVidia cards at folding even though the theoretical FLOPS are higher.  There's plenty of work to be done before ATI is even competitive to CUDA which seems to be more widely supported, but I suppose their focus is on the graphics rather than the GPGPU side.
