Forum > GPU crunching

- POLL - : SETI@home on ATI GPU - you have, or you will buy an ATI GPU?

(1/6) > >>

Sutaru Tsureku:
AFAIK, the new BOINC DEV-V6.10.x support ATI GPUs.

I'm not up-to-date, it will be possible to crunch soon SETI@home WUs also on ATI GPUs?
If yes, when? ;)

And, who make this difficult/hard coding?

How will be the performance of the ATI GPUs?
From reports in the internet I read that they have double or much more GFLOPS as the nVIDIA GPUs.


Maybe interesting for the coder/SETI@home crew.. made a poll with this thread.  :)

Sutaru Tsureku:
Thanks a lot for voting! :)


But now I get the idea.. after posting about the poll here at the SETI@home forum.. that somebody could make funny things.. vote two times.. here anonymous and there public..


So.. sorry.. please vote ONLY in the SETI@home forum..
http://setiathome.berkeley.edu/forum_thread.php?id=55445
If you voted already here.. please vote also in the SETI@home thread. I'm sorry..  :-[

I guess everybody have an account at SETI@home.. ;)


So I close the poll here.

Sutaru Tsureku:
..also I extended the poll in the SETI@home forum/thread with number IX. ..

But maybe someone (of the opt. crew) could answer this..?

Thanks! :)

Hi Sutaru, [Posting on SaH thread]
   Myself I don't have an ATi GPU ...So my vote has to be "III. NO - I don't have an ATI GPU"...   well actually I do have some ancient AGP cards in a box somewhere that are not up to modern standards, so wouldn't work.  I do know there are at least a couple of us that do have more modern cards of that brand.  My GPU acquisitions have come from either kind friends, or the scrapheap, due to financial limitations.  I find it very difficult to justify, for my own situation, to buy a large card that will use lots of power, and need me to upgrade power supply etc.

IMO a multibeam port to Ati GPU would be difficult, not impossible.  Maybe OpenCL will help the convergence of builds, reducing the duplication of effort among brands.  Experience with that language though, takes as much time to learn as any other language though. 

There are technical challenges in working with GPU code & hardware we're all still coming to grips with. Perhaps over time the picture will change, though I doubt it would be quickly.  That's partly because of some specific technical challenges with the multibeam algorithms, mapping to new hardware. Time limitations, AFAIK, play some part for all of us, as well as hardware costs & development support tool/library/language capabilities & quality have been described as limited by some who've tried.  That slows things down.
