Hey,

I've been running SETI@home for a while now, and on Windows 7 and XP I used to be able to run both Astropulse and "classic" SETI WUs. However, on Ubuntu I'm only able to run Astropulse. I remember fixing this very same problem on Windows with adding CUDA_GRID_SIZE_COMPAT as an entry in environment variables. I've always been running SETI@home with my Gigabyte Geforce GTX 660 OC.

Is there any way to make "classic" units work on my GPU in Ubuntu rather than just the Astropulse ones? It takes 2-3 hours on one CPU core to complete a classic unit in Ubuntu, while on Windows these units would complete in 2-3 minutes on my GPU. I'm happy running Astropulse, but it would be nice to run SETI@home all week.

I would very much appreciate any help you could give me!

Your sincerely,
Ragnar

Have you checked Seti@home v7 in your computing preferences?

On your computer in Tools -> Computing Preferences -> Processor Usage, set Use at most xx% of processors to 0 to avoid MB (and AP) WUs running on your CPU.

Thanks for the suggestion! Hmm, I've already disabled the CPU tasks via berkeley.edu. I tried what you suggested, however, but no GPU work gets downloaded. The problem has to do with not receiving any other work units on my GPU besides the ones I get every now and then from Astropulse. I haven't been doing any CPU work for a long while, that's not the issue.

Also, on Tools -> Computing Preferences -> network usage, make sure min. work is (say) 2 days rather than 0 (the default). Otherwise BOINC won't send work for apps you don't already have work for.

So you want MB workunits on your GPU? At the moment there's no stock Linux NVIDIA apps for MB, only AP.

There's a thread somewhere on this board about a beta testing Linux apps. You could try that.
