BOINC first starts up and these message appear in the event log:

2/23/2024 2:53:33 PM | | OpenCL: NVIDIA GPU 1 (ignored by config): NVIDIA GeForce GTX 1070 (driver version 551.23, device version OpenCL 3.0 CUDA, 8192MB, 8192MB available, 6852 GFLOPS peak)

My cconfig does not have any GPU exclusions (via Options group). Where is this "ignored by config" coming from? (for the GTX 1070)

Thank you for your help,
Steve

You have two Nvidia GPUs. BOINC uses only the best of the same brand GPUs, when more than 1 is in the system and detected. The other one will be ignored. Because you don't have anything in cc_config.xml, BOINC follows those preferences.

If you want to use both GPUs, add the following to your cc_config.xml file.

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


You can make a cc_config.xml file with Notepad (if Windows).
Add the above, then save as an all files option, so it doesn't end in .txt
Save to your BOINC Data directory.

A restart of the BOINC client is required to make use of this.
