Hi, I'm rather stuck and would appreciate some guidance to get my new GPU to crunch some work.

I've just installed an MSI 275gtx lighting (1792mb RAM) along with the new 190.32 drivers.

OS Ubuntu 9.04 Jaunty

BOINC log:

Mon 28 Sep 2009 10:34:10 BST SETI@home Message from server: No work sent


After reading through the forums a some, I've added

<use_all_gpus>1</use_all_gpus>
<no_gpus>0</no_gpus>

to the cc_config.xml

The card has been in for a few days now, but still no work?

I know that Lunatics is available, but for the time being would like to stick with the stock apps.

Is there anything I should do to prod the app/GPU to play nice?

Thanks.

Seti has only got a CUDA application for Windows. Not for the Mac, not for Linux. You can check available applications at http://setiathome.berkeley.edu/apps.php.
So you will have to do with the Lunatics or other 3rd party application anyway.

By the way, do you have any reason why you're using BOINC 6.10.6, which is a development version with certified bugs in it? If you're not testing the software, use the recommended 6.6.40 instead. If you are testing, I have said nothing. ;-)

Also, put on some log flags in your cc_config.xml file, which will make things more clear for a next time you add a log:
<cpu_sched_debug>: problems involving the choice of applications to run.
<work_fetch_debug>: problems involving work fetch (which projects are asked for work, and how much).

Last thing, your videocard only has one GPU, right? It's the only GPU in your system? Then you don't need <use_all_gpus>, as BOINC will be using all of them already. (Whether or not the project's science application will, is something different).

Thanks for prompt reply. I guess I didn't look hard enough to notice no CUDA for Linux. I 'assumed' that CUDA was available as the client was requesting WU's.

I was using 6.6.40, but it didn't detect the GPU at all, so I upgraded to 6.10.6.

I added the options flags as a brute force mechanism to be honest...

I guess I'll go have a look at the Lunatics stuff

Thanks.

Hi, this an ATI driver/DLL :

Yes, that was quite normal to get those errors on 6.10.6, as it wouldn't hide them under the <coproc_debug> flag which later versions do.

BOINC 6.10 will look for both Nvidia and ATI GPUs, looking if it can find the correct library files.

So with the <coproc_debug> flag set the newer messages are:
09-Oct-09 12:43:04 ATI GPU 0: ATI Radeon HD 3800 (RV670) (CAL version 1.4.403, 512MB, 428GFLOPS)
09-Oct-09 12:43:04 No NVIDIA library found

And vice versa of course if no ATI GPU is found.
