Mixing GPUs in Seti

dekez · 27 Jan 2011 at 19:26

Guys I've just put a 460 in to my rig which already has a 260 in it running seti.

Now in boinc it says it's using GPU 1 (the 460) but it says GPU 0 (not used).

So it detects it fine but isn't using it, I've tried looking in the preferences and I can't find anywhere to enable multiple GPUs, any suggestions?

Cheers

cc_config.xml

<use_all_gpus>0|1</use_all_gpus>
If 1, use all GPUs (otherwise only the most capable ones are used). - New in 6.6.25

Cheers Biffa that worked

Although now, looking at the cuda tasks, one is completing a task, the other is just moving down through them, after about 19 seconds it turns to 100% - ready to report then does the same with the next task :confused:

I've suspended work for the moment as it just seems to be wasting tasks, I'm going to wait and see what error they come back with once they're processed.

Sounds like they are EUE'ing I use BoincTasks to monitor mine and the EUE's show as red.

Strange, I've been folding on both cards since I've turned boinc off with no problems, installed boinc tasks and you're right they are coming up in red. I guess the only thing left to try is to completely reinstall everything.

It could be that its trying to fold Fermi WU's on the 260? Might need to massage your app_info.xml

Thanks Biffa I've had a look at the xml but need to have a bit of a read up on what it all means when I have a bit more time.

Annoyingly now I can't even get folding to run on both cards now, and I know what I'm doing with that! This is the last time I mix GPUs!
