SETI MB CUDA for Linux
IanJ:
Sunu,
Regarding my 9600GT Xid errors. I have 190.18 cuda libraries which as you know is 2.3, you speak of trying other higher 190.xx versions, where do I get them from the Nvidia download site, as it seems only to have one version, 190.18, the one I'm using?
Thanks
Ian

You can find them in ftp://download.nvidia.com/XFree86/Linux-x86_64/ Every folder has three files, you need the ...pkg2.run one.

Sunu,
I have tried 190.25, 190.32 and 190.36. They all continue to have the problem of the NVRM Xid. I will continue to use 190.36 for the time being.

Hey all.
I've recently upgraded to Kubuntu 9.10, which is running a 2.6.31 kernel, and, as I've noticed with any kernel 2.6.29 and beyond, the CUDA units take a REALLY long time.
Look at this unit :
http://setiathome.berkeley.edu/result.php?resultid=1407056493
compared with this one :
http://setiathome.berkeley.edu/result.php?resultid=1401862775
The "CPU" time is about the same, but the actual runtime goes from 13 minutes to over an hour.
Any suggestions ?
All other GPU/CUDA benchmarks indicate that everything else is working fine.

What priority do your seti apps (CPU and GPU) run?
In sidux (uses 2.6.31-5) I've seen way too slow crunching with the default priorities, 19 for CPU and 10 for GPU tasks. Renicing the GPU tasks to 0, they speeded up considerably. Maybe newer kernels need more aggressive priority levels for cuda.
I'm using the script attached below to renice the cuda tasks to 0 (it runs in infinite loop, checking every 5 seconds for seti cuda tasks, renicing them to 0).
