As some one mentioned, we would DEARLY love to have the project crunch on individual GPUs rather than use all in the machine. It is more efficient for the computers and more work would get done for the project.

Hi,

I understand that request but unfortunately this is not up to me. Distributed.net Client doesn't allow selecting which GPU they use and they detect and use all of them. Until they support this switch, there's nothing much I can do. Sorry. :(

Assuming this project is built on DNETC sources: Was something changed in the ATI application.

I'm using Distributed.net Client without any changes just like they are on their download site. I don't have their sources so I can't build a custom client (there's also no need for such thing).

One of the two GPUs only gets back up to 50% GPU usage after it finished the first segment (block of work). Previously both GPUs were running over 90% GPU usage the whole time, except for the end when the faster GPU has to wait for the slower on to finish it's last segment.

Interesting as it should behave like the latter part. That's also how it works on my own system (and on many others too, I would hope). This can be a bug in the dnet client but there's also some changes I can do in my wrapper code to see if things improve.

I believe this is also something dnetc@home battled with some earlier versions of their apps. Not sure if they ever got it working since I obviously didn't have that problem. :)
