Hi,

I don't know about gui solution but here is the CC_CONFIG of one of my BOINC clients, among other thing it tells BOINC to ignore GPU #1. In this case (my case) it will use GPU #0.

<cc_config>
<options>
<allow_multiple_clients>1</allow_multiple_clients>
<allow_remote_gui_rpc>1</allow_remote_gui_rpc>
<use_all_gpus>1</use_all_gpus>
<ignore_nvidia_dev>1</ignore_nvidia_dev>
<report_results_immediately>1</report_results_immediately>
</options>
</cc_config>

What if i want specific PG tasks to run on card0 vs card1?

ie. Card0 - GFN17-mega, Card1 - PPS Sieve.

If I want to exclude a gpu from multiple apps, do simply create multiple <exclude_gpu> sections listing each app? (I tried this and it didn't work). Or is there some other magic like comma separating app names?

Nah, that can be done with some config file magic:

<exclude_gpu> <url>http://www.primegrid.com/</url> <device_num>0</device_num> <app>pps_sr2sieve</app> </exclude_gpu> <exclude_gpu> <url>http://www.primegrid.com/</url> <device_num>1</device_num> <app>genefer17mega</app> </exclude_gpu>

My system would only use 1 GPU until I updated my cc_config.xml in my BOINC directory:

Then my attempt to have my 1060 do generfer18 and the 2080ti do something else (in this case genefer19).

My cc_config.xml that is in my BOINC\projects\www.primegrid.com directory.

<cc_config> <options> <exclude_gpu> <url>http://www.primegrid.com/</url> <device_num>0</device_num> <app>genefer18</app> </exclude_gpu> <exclude_gpu> <url>http://www.primegrid.com/</url> <device_num>1</device_num> <app>genefer19</app> </exclude_gpu> </options> </cc_config>

Both GPU's are running 19's with this config. Clearly I need to learn something. :)

and that just goes in cc_config.xml in the primegrid project directory?

Correct. Under

Thanks.

What's confusing is where it all goes. In the responses above the cc_config.xml can go in the project directory (if I'm reading it right). So it appears it can go in both places?

I sort of think of the two files like this:

capitalization for effect only
CC_config.xml = Computer Config -> general configuration of BOINC for the computer.

APP_config.xml = All Project Preferences -> preferences for that particular project.

It's not perfect, but it keeps me from getting confused about the two.

Anything you change in cc_config.xml affects BOINC, everything in BOINC.

Anything you change in an app_config.xml only affects that specific project.

This is the reason for the locations of the files also.

cc_config.xml is in the C:\Program Data\BOINC folder on Windows because it affects all of BOINC.

The app_config.xml files are in specific project folders because they only affect that project and nothing else. Plus you can't have two files names app_config.xml in the same folder.

Like I said, this is how I look at it to make my life easier. I hope it helps someone else clear up any confusion.

Also, there is a great guide over on overclockers.net I believe for running multiple instances of BOINC on the same computer for various reasons. I do this and run 3 instances. One is CPU only, one is for GPU0 only and one for GPU1 only. Each GPU instance has it's own venue at each project I run and I can select not only which projects are ran by that card, but which sub-projects from that project if it offers sub-projects. I set it up on Linux after only using it for maybe a week. If anyone needs any help, PM me and I'll do what I can.

Thanks John, this was super helpful. It's a little tedious but I did eventually get it to work.
