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. :)
-
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.
-
..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.

I have an old 2600 XT desktop card and a relative has a 3470 mobile card just waiting to crunch. On my 4650 mobility I'm folding at 98%, and I would love to crunch with the other cards, for seti. Since SETI has so many optimizations, the move towards an ati application seams logical. Plus the 6.10.x x64 client, running on collatz, gives too many errors, and seti would be ok if you have older cards, and you don't have to worry that you cannot finish a task in time (speaking of course about folding).

Sorry but I don't understand how to vote.
I do login but I don't see any button to press, using firefox on win-xp-home

The vote is being run in the thread on the SETI forums.

Any news on the ATI applications, maybe start a new thread for closed or open beta?

What ATI GPU you have?

mobility 4650 on win 7 x64 with Cat 9.7 (I'm using what's available from win update, don't want to manual install the drivers)
-

Catalyst 9.2 or less required if you want do alpha testing.

From SETI main forums I know that also you have lesser GPUs doing nothing now.
"
2. It's really a waste that I cannot fold on the other cards, especially if I could limit the gpu usage somehow to go unnoticed, but still crunch better than the cpu version.
"
You could join alpha testing with these lesses GPUs if requirement of Catalyst <=9.2 is acceptable for that hosts.

one computer upgraded:
win xp x64 SP2 (MUI Spaniard)
Athlon x2
ATI HD 3850 Driver and CCC 9.2 installed
I'm willing to do Alpha, Beta ... Omega testing ;)
now running with this computer MW ATI 0.20 x64 (like a thunderstrom)
-
I can do alpha testing if you want
WinXP 32 bit
HD4870 and 9800gtx+ in the same PC
-
Does the requirement for Catalyst 9.2 still stay? I have an HD3870 with catalyst 9.8 and i really want to join alpha.
-
beta already run and yes, no more than 9.2 required.
Blame ATI for driver degradation, new versions dont support large arrays...

Well, time to hear the 4870x2 does on full load.

Is there any outlook on it changing anytime soon? Have my 3870-OC crunching away at MW, but would love seti to share in the fun as well. The only problem I have is my win7 x64 isn't entirely stable with drivers prior to 9.5; when accelerating high definition movies, or is this an issue we'll have to take up with ATI?
-
Absolutely and solely with ATI.
Surely have no intentions to debug their drivers! >:(
-
That would indeed be slightly beyond what of end-users or even developers are supposed to do :-).
Is it a bug, or have they purpousfully scrapped it? If its a bug, I'll report it; if they have scrapped it all we can do is beg (politely)...
-
My 4830 has no problem running the 9.2 drivers on Win 7-64. Of course I did install it without CCC, so that might be part of it.

I'm with you. If you post a beg/bug report post the link here so all users interested (including myself) can support the request!

This limitation may (or may not) go away with new OpenCL-enabled drivers.
BTW, OpenCL SDK from ATI supports GPUs starting from 4xxx only, that is, currently supported HD2xxx-HD3xxx will be abandoned in OpenCL ports :(
-
And more:
"
This is a performance hit compared to a streaming model because the GPU is natively a streaming device. There is another performance hit for the R7XX since it was not designed with OpenCL in mind, our new HD5XXX series was.
"
So don't expect much from OpenCL on HD4xxx .... ATI is clearly behind nVidia in general purpose computing.

I have a Radeon HD4870 running Windows 7 and catalyst version 9.9. MW ATI app works fine. Like to run SETI (Beta) ATI app. Possible???
-
catalyst 9.2 and "Squire" status required.

Thnx Raistmer. I will downgrade to catalyst 9.2. I hope to get Squire status soon.

A collection of ATI cards waiting to test ;D 4890, 4850 an even a 3200 IGP. Currently burning through WU's on MW@home.
