Ok so I have spent a few days trying to figure it out but have no luck.
What I thought of doing was running 2 instances of BOINC clients with seperate directories.


1st Client dedicating 1st slotted GPU towards Collatz.

<cc_config>
<options>
<data_dir>FIRST CLIENT LOCATION</data_dir>
<use_all_gpus>1</use_all_gpus>
<ignore_cuda_dev>1</ignore_cuda_dev>
</options>
</cc_config>

2nd Client dedicating 2nd slotted GPU towards DNETC.

<cc_config>
<options>
<data_dir>SECOND CLIENT LOCATION</data_dir>
<use_all_gpus>1</use_all_gpus>
<ignore_cuda_dev>0</ignore_cuda_dev>
</options>
</cc_config>

How would I get something like this to work?

Also looked into changing the "app_info.xml" but nothing worked the way I wanted to.

Is there an easier method, if so please point me to the right direction.

Thank you. :)

How did you separate the registry entries for the two clients? ;-)

I didn't thats why I am asking if there is a way to do it, hence this being a question. :p

Is there a method to dedicate 1 task per GPU?

Specifically DNETC likes to use 2 GPUs for 1 tasks, but there is other reasons why I am looking for a solution to this.

I'm open to suggestions.

Hi, is this cc_confiig.xml file sufficient to prevent GPU 0 from being used?

<cc_config>
<options>
<use_all_gpus>0</use_all_gpus>
<ignore_cuda_dev>0</ignore_cuda_dev>
</options>
</cc_config>

XPx86, i7-920, boinc 6.10.58, two GTX470's.

Thanks,

Could be, but you can make sure by looking at your Messages tab. There most configuration items are listed at startup time.

I would suggest <use_all_gpus>1</use_all_gpus> though.

After both a read and a restart nothing changed; still using 2 GPUs. Per chance, do existing tasks have to complete first?

- Or even, would I need to remove card 0 from the system, reboot, start Boinc and then shut down, install the card, reboot and start Boinc again?

Thanks,

OK, looks like running and queued tasks need to finish/get terminated, a project detatch or reset, several restarts and so on need to be done for this to work.

What about the log entries for the GPUs? Maybe one is marked as "not used".
