I'll be ending participation here shortly and I just wanted to say that I never saw or found any direct solution to the problem on the boards here or anywhere else. Using a (lesser) single AMD card was the only solution I found. For some, you have to either take a GPU out or live with the app using them all.

I'm not having the multiple CPU on one work unit problem, but clearly this project doesn't work reliably with BOINC. Projects running on VirtualBox are better behaved than this one, as far as respecting BOINC restrictions. I am crunching on an AMD card for now, but that is not optimal. Hopefully someone has a solution.

I also tried a project-specific exclusion in cc_config and that didn't work either.


Do this:

<cc_config>
<options>
<use_all_gpus>1</use_all_gpus>
<exclude_gpu>
<url>http://moowrap.net/</url>
<device_num>1</device_num>
</exclude_gpu>
</options>
</cc_config>

Thanks for the response. I had already tried that before posting. As I said, a project-specific exclusion in cc_config does not work. That includes this:

<exclude_gpu>
<url>http://moowrap.net/</url>
<device_num>1</device_num>
<type>NVIDIA</type>
</exclude_gpu>

as well as what you suggested.

I've been using this since I set up the client and it doesn't work either:

<ignore_nvidia_dev>1</ignore_nvidia_dev>

Is anyone successfully using cc_config or app_config to limit the CUDA app?

Thanks for the response. Each GPU has its own client, with GPU exclusions defined in cc_config so that shouldn't be necessary. I went ahead and tried this:

<app_config>

<app_version>
<app_name>dnetc</app_name>
<plan_class>cuda31</plan_class>
<avg_ncpus>1</avg_ncpus>
<ngpus>1</ngpus>
</app_version>

</app_config>


(Code tags seem broken, using it put the above all on one line.)

It had no effect.

I also tried a project-specific exclusion in cc_config and that didn't work either.

I have found I can suspend BOINC and edit the dnetc-gpu-1.3.ini file in the slot, changing run-work-limit from -1 to 1. Obviously that's not a practical solution. Edits to that file in the project folder do not hold, I suppose because changes cause it to no longer match the file signature and it downloads a new one.

Is there anything else I might try?

I thought I'd try crunching this again after a long absence. I found that the app ignores BOINC settings and uses every GPU in the system. Apparently this is how it is supposed to work. This is not desirable for a number of reasons. Is there a way to limit it to one?
