I have a 960 and 950 in a Win 7 system. I was previously only letting BOINC use the 950, this morning I removed that restriction so the 960 could be used. Moo is assigning both GPUs to the same work unit. i.e.

Running (0.2 CPUs + 2 NVIDIA GPUs (devices 0,1))

However if I look at the GPU usage only the 950 (device 1) is actually being used. It is also running these work units much more quickly than before, about 110 seconds each.

Copy and paste this into NOTEPAD and then save it as a txt type file with the name cc_config.xml
into the folder c:\programfiles\boinc and exit and then restart Boinc and it should start using both gpu's

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
</options>
</cc_config>

If you already have a cc_config.xml file just add the lines into the existing file.

Yes I have that in the cc_config already. The system is currently running 2 Enigma GPU tasks at the same time with no issue.

So it works elsewhere but you are saying here 2 units are both running on one gpu? I just checked the settings and they don't mention that at all.

No what I am saying is both GPUs are being assigned to a single work unit, something I have never seen before on other projects. So in Boinc manager status it looks like:

Moo! Wrapper Running(0.2 CPUs + 2 NVIDIA GPUs (devices 0, 1))

But again only one of the GPUs is showing any usage. I tried resetting the project but that did not change it. I will remove and re add it next, after I finish the current work units.

I didn't think that was possible using current thinking and Boinc. I know gamers do it all the time but not in Boinc.
