At issue is I run Seti and it "always" runs on the Gpu. The gpu is setup to use 1 core.

So is CSG doing some kind of cpu-based multi-threading or is there something else I need to troubleshoot?

Thanks,
Tom

Some GPU apps will work as you think they should and others you need to do the following:
If in Simple View click View then Advanced View.
From Advanced View click Options then Computing Preferences...
In the dialog that opens change "Use at most ____ % of the CPUs" from 100 to 87.5.

Hi Tom,

CSG does not do cpu multi-threading, nor does it have a GPU app so .. the only way I could think the you would have 9 tasks with accumulated work was if two of those tasks were in the waiting-to-run state ( having been started and then superceeded by CSG tasks with a earlier deadline ).

If nine CSG tasks were running along with a Seti GPU task .. I have not a clue. It should not happen.

What are the 9 tasks? 8 CPU and 1 GPU. That's normal for some projects.
