For the moment i have a GTX 260 and 280.
I would like to knon if it's possible to put them together?

If this is the case, it seems to me to have read in a post on the forum, that you could put an application for this purpose.
Is this true and when i can expected to made some test?

Jim PROFIT

If you are ready, we are ready.

The current BOINC client (6.3.8) should detect multiple GPUs and run one GPUGRID instance per device. However, we have not yet tested this feature so cannot guarantee that it will work.

Does the Windows version not support multigpu?
As I have 2 8800GT's, Boinc lists them both when it starts up, however only 1 task ever runs.

This is something to start off with.
So, you are on client 6.3.8. Can you paste here the message where the client report two GPUs?

The application should work.

When I run Boinc v6.3.8 after the "development" warning, and it's listing of my Computer info it shows:
CUDA devices found
Coprocessor: GeForce 8800 GT (1)
Coprocessor: GeForce 8800 GT (1)

I would suggest turning on debug flags for the scheduler. When I did this I got messages like this
8/20/2008 12:56:04 PM||insufficient coproc CUDA (1 + 1 > 1)
Which for me is correct since I only have 1 GPU it can not run 2.
This probably would help find out why it will not run 2.

Is that what is explained at http://boinc.berkeley.edu/wiki/Client_configuration , in the CPU scheduling bit?

It's saying "20/08/2008 23:45:59||insufficient coproc CUDA (1 + 1 > 1)"

I guess even though Boinc is seeing both 8800GT's, for some reason either it or the project thinks I only have 1?

Thanks for the testing. I've reported this to the developers to let them have a look into, I think GDF is asleep now. If they need more info I'll let you know.

I'm told by Dr.Anderson a fix for this has been checked in, It should appear in the next client release also.

New version 6.3.9 has the fix.

Please try.

And the BOINC Client is still crashing on Vista 64 bit... :(

Reported again to Berkeley.

gdf

I'm waiting until the new Windows app is released before I give it a try.
As if the new windows app brings the speed to near where Linux is then it be better to wait.

That's assuming It can actually do the workinuits without crashing :(

Boinc 6.3.9 is not working for me on Windows XP x64 either.
6.3.8 workes fine, however 6.3.9 just sits at "Connecting to Localhost"
And if I try to start the Boinc Service it just gives me an error about it "Terminating abnormally"

No, unfortunately not...
The BOINC Client isn't crashing anymore, but I still have problems with the coprocessor detection on the Vista 64bit host with 177.84 nvidia drivers on a GTX260 card with BOINC 6.3.10 Windows x86_64.

BOINC shows only
25.08.2008 19:51:11||CUDA devices found
25.08.2008 19:51:11||Coprocessor: Device Emulation (CPU) (1)
25.08.2008 19:51:11||Version change (6.2.18 -> 6.3.10)

I wait for the Linux version which will support multi GPU.

But, is there someone who know when we can expected this version?

Jim PROFIT

The new application 6.3.10 for linux is ready to download.

Member Feuerkater from our team is able to crunch on two 8800GT in parallel, so basically it works :) He is using 6.3.10 on Vista 64bit.

I can see that you are crunching on both GPUs, the GTX260 and GTX280, but are you doing it at the same time? Do you have two WUs running at once?

Boinc see only one GPU.
Maybe i have to use the same GPU.

If you have multiple GPUs, you'll need to disable SLI mode in order to use them both for crunching.
