Perhaps this has been answered but I can't seem to find a related positing. I've got two (2) GPU's and according to the BOINC Manager Tasks tab both GPU's are processing work units. However, there is no load on GPU #2. Tasks assigned to it run, complete but it doesn't appear that the GPU is doing a thing. I'm monitoring with MSi Afterburner. GPU #1 at ~ 95%, GPU #2 at ~ 0%. Is this normal?

Yes, that's normal behaviour of SRbase, You can use only one gpu. BOINC does run two wu's but both of them are running on device 0.

In FAQ http://srbase.my-firewall.org/sr5/forum_thread.php?id=6&postid=5765#5765 is solution to run only one GPU and free another to other projects.

So your saying, no matter what I do I can only run one (1) GPU? The FAQ offers configuration info for the cc_config file. To exclude, which I wasn't planning to do, and to use all GPU's which I am using <use_all_gpus>1</use_all_gpus>. That's different behavior than with the other projects I participate in.

Very good. Thank you, all, for clarifying.

Hello,
I have two GPU.
WU runs on both. Two WU at same time. One on device 0 and a second on device 1 !
