I've been using BOINC for a long time but up until now I've never had a GPU able to crunch with. I just purchased an AMD Radeon HD6950 2GB and I can't get BOINC to detect my GPU. I tried following the directions for GPU computing with Linux, but I can't seem to make it work. As soon as BOINC loads it says "No usable GPUs found."

I've tried it with both AMD's 12.4 and 12.6 Beta drivers and all sorts of options in the cc_config.xml file. Perhaps I'm missing something? I'm running BOINC 7.0.25 with the 2.6.37.6 kernel.

Thanks.

One question, have you tried shutting down the client and then restarting it.

Not restarting the machine, but the BOINC daemon.

I have seen where BOINC does not detect the GPU until later in the boot process.

Yes, I've tried that. also deleting the self-generated configuration files, and add/removing projects.

I posted on the regular boinc forums and got my answer.

http://boinc.berkeley.edu/dev/forum_thread.php?id=7681#44805

FYI, now that it's running, a work unit that took my CPU ~2 hours and 20 minutes to complete, takes my GPU ~1 minute and 50 seconds to complete. And it's only using 90% of the GPU.
