I did also run some tests on 9.10 with 2.6.31, but my hosts don't seem to fail even with 9.04.
9.10alpha6 is ~3% slower per wu.

Could get SETI to run with Optimized apps but they were alot slower than the Windows ones, had my GTX275 clocked higher than on Windows, but they still ran alot slower

In my case (64bit openSUSE 11.2) I have improved CUDA-crunching with simple renicing:

$ sudo crontab -e
*/2 * * * * if [ `ps -o nice --no-headers -p $(pgrep setiathome-6.08)` == 10 ]; then renice 6 `pgrep setiathome-6.08` > /dev/null; fi
:wq
$

How to do this on Dotsch_UX linux?
An if I may ask what is speed up with this command? -1% 5% 10% ?

Pepi, make a file named for example seti_gpu.sh and inside put:

Code: [Select]
#!/bin/sh
while true
do
for arg in `ps -Lo lwp --no-headers -p $(pgrep setiathome-6)`
do
renice 0 -p ${arg}
done
sleep 5
done

and then run it from a console (it might have to be a root console in your distro or run it with sudo).

You'll need to have the bsdutils and procps packages installed.
