I just upgraded from boinc_6.6.41_x86_64-pc-linux-gnu.sh to boinc_6.10.17_x86_64-pc-linux-gnu.sh. And suddenly my GPU is not detected anymore:

"No usable GPUs found"

Argh! 2 Lines above:

"cDriverGetVersion() missing from NVIDIA library"

I guess the "No usable GPUs found" is a follow up result of the missing "cuDriverGetVersion()" call, isn't it?

So, do I need a newer NVIDIA driver?

Since you don't say what driver you are using now, nor which Linux version, it's hard to tell.

Ubuntu 9.04, NVIDIA driver 180.44

Ah, and what Nvidia GPU? if anything, you could try the 190.42s.

9400. BUt hey, the GPU was correctly detected and used in the former 6.6.4 version!

I am also having the same problem after "upgrading" to BOINC 6.10.18 from 6.6.41. This is a newly built system, Windows 7-64 bit and has been running BOINC 24/7 for a couple of weeks. GTX 275, driver 191.07

I will downgrade to 6.6.38 and see if that fixes it. At the moment, I think there is a bug in 6.10.18.

Still no good. Next I will try downgrading the driver to 190.38 (Note: I did NOT upgrade the driver to 191.07 when upgrading BOINC to 6.10.18. It was running stable with 191.07 and BOINC 6.6.41)

Nope - that's not it either. Driver 190.38, BOINC 6.6.38 doesn't work either. I give up until someone can give me an idea of something else to try.

The problem is shown in the 4th line down:

Running as a daemon

In other words, you've installed BOINC in "protected mode", (formally known as "service mode").
As has been mentioned many times, you CAN'T run gpu's in this mode!

See also this FAQ.

Thank you. I feel like such a fool as it says it won't work with Vista (and I know implied Windows 7 too) right in the text next to the check box. My only excuse is that I have some Windows XP boxes too and as everyone knows the daemon service works just fine there.

I will now search the forum to see if there is any possibility to get the daemon service working on Vista / Win-7. I suspect the answer is "no" and is due to some MS issue. Thank you for the prompt answer. I am happily running my GPU now.

It IS an MS issue, as explained in the FAQ that I linked to. :)

Hello,

I'll write to this older thread since I have a similar issue on my test system (Ubuntu 9.10):

I installed BOINC normally so it is installed as a daemon. After that I downloaded the actual linux package (6.10.36) and made the necessary changes so it is used instead of the "original" one. Also I installed the CUDA drivers.

Now, when the system starts, BOINC reports no GPU:

But when I do a "sudo /etc/init.d/boinc-client restart" it IS found:

How can this be?
Or better said: How can I correct this?

Perhaps it's the access rights for the BOINC user to the /dev directory.

Computer sind nicht alles im Leben. (Kleiner Scherz)

Either that, or a slow/late loading video driver.

Thanks. Since the driver is found on restart, I'd think the it's the driver. Can I make sure BOINC is started afterwards?

Torsten

seemingly a change in /etc/rc2.d did it: I couldn't identify what is the driver in question, so I renamed "S20boinc-client" to "S80boinc-client".
2 restarts later the client still detects the GPU, so I believe it's solved. Otherwise I'll come back here. ;)

Torsten

too bad - today I've seen "no GPU's" again... :(
So, is there a way to further delay the start of the BOINC client or otherwise make sure the driver is completely loaded before?

Manually start BOINC after your OS has fully loaded, or add the start-up logic to a batch file that will only start the client after so many minutes. BOINC does come with a --start_delay option, but this is for applications only, not for the client itself.

Manually start BOINC after your OS has fully loaded.

I tend to forget manual actions. :-P
Normally I only see those issues only in Windows (not knowing which services start in which order); I thought *IX would handle it better... :(

I edited something into my answer above.

How to add a start-delay in a batch file? Ping 127.0.0.1 300 times will add a 5 minute delay. So something like this:

Rem Start delay BOINC
@ECHO OFF
Rem pinging localhost 300 times for 5 minute delay
ping 127.0.0.1 /n 300
/path/to/BOINC-binary/boinc-client
/path/to/BM-binary/boinc-manager
