Hey guys,

some time ago i got a cuda capable graphic card and i tried to configure my boinc software to use ONLY the GPU cause i need the CPU for other tasks. :)

I Managed to disable the cpu by the settings on the webpage (in my profile) but i never got one GPU WU. I don't know whats going wrong.

Here is the data i get from my system:

First the startup with graphic card infos: (i'm using the latest nvidia beta driver for linux 195.22)

And here is the message i get over and over again:

Does anyone know whats going wrong here?

Thx

Did you set your SETI@home preferences to

Run only the selected applications -  SETI@home Enhanced: yes

or at least

If no work for selected applications is available, accept work from other applications? yes

? Since AstroPulse doesn't run on the CUDA GPU.

Gundolf

Computer sind nicht alles im Leben. (Kleiner Scherz)

SETI@home classic workunits 3,758
SETI@home classic CPU time 66,520 hours

Hi Gundolf,

this are my setting:

Run only the selected applications	SETI@home Enhanced: yes
Astropulse: yes
Astropulse v5: yes
If no work for selected applications is available, accept work from other applications?	yes

thx for your quick answer.

Sorry, then you'll have to wait for the client scheduling unix experts for help :-)

Gruß,
Gundolf

ok, thx anyway Gundolf, i will wait. ;)

I don't see any mention of an anonymous platform being used. Seti only has a CUDA application for Windows, the other platforms aren't supported yet. You will have to use a 3rd party application with anonymous platform file (app_info.xml) in order to use CUDA. Check Crunch3r's website for CUDA apps for Linux.

Hi Ageless,

thx for answering. I'm a bit confused, cause on the official seti@home page in the faq, CUDA support for linux is mentioned. See here: http://setiathome.berkeley.edu/cuda.php .

I looked for a cuda 32bit linux client on the page you mentioned but the link seems to be down. I think i will wait until seti releases a cuda enabled linux client. Its a bit strange.. boinc supports it but seti not.. :)

Anyway.. thx for your infos.

That page is a year old and hasn't been updated in a long time. It also says you can't run Seti tasks on CPU and GPU at the same time, which has been possible since December 2008.

I looked for a cuda 32bit linux client on the page you mentioned but the link seems to be down. I think i will wait until seti releases a cuda enabled linux client.

Watch your terminology.

Client = BOINC.
Application = Seti_Enhanced, Seti_Enhanced_CUDA, Astropulse.

I see he has taken down his Seti_Enhanced_CUDA applications for Linux. So sorry, there are none anymore. If you know your way around a compiler, you can try to compile the Seti CUDA source code all by your self.

Its a bit strange.. boinc supports it but seti not.. :)

Not too strange. BOINC is way more than just Seti. So you can attach to GPUGrid (requires Linux 64bit), Milkyway@Home (requires Linux 64bit), Collatz (both 32bit and 64bit Linux) or Einstein@Home (32bit Linux) and use your CUDA card there. Not all projects are stable, some require you to have the latest hardware and BOINC version. Drivers need always be very much up-to-date.

Thx Ageless for you words.

My terminology was wrong, you are right but i was talking about the right things. :) I know what boinc seti and cuda are, so i only used the wrong words to explain what i mean. :)

If http://setiathome.berkeley.edu/cuda.php is really that old, someone should update it cause its the first place new users are looking at. Documentation is as important as the program itself. ;)

thx for the sourcecode hint. I will try to compile it by myself, cause i'm only interested in seti. :)

Thx again for you help, maybe i will come back to you later. ;)

people should just look at my FAQ on the subject. It holds a lot more information. :-)

Yes i saw that FAQ before but its a general boinc FAQ and users like me does not necessarily know that seti@home does not support CUDA on linux. They read

1. You will need at minimum BOINC 6.4.5 (or newer) (Windows, Linux and Macintosh).

and think tahts it. :)

I think Chrunch3R took down the 32bit Linux Cuda app since it didn't work correctly, while the 64bit does work correctly, and is still there.

There are a couple of threads here on installing the Linux Cuda app, and a couple of different versions of the app spread about within the threads.
