Hi community. I don't know if this is the right place, here.
I installed nvidia-cuda-sdk-2.02.0807.1535 & nvidia-cuda-toolkit-2.3, both - at first ~x86, then ~amd64 .. which failed on ~amd64 at first because of missing librarys. (libcuda,libcufft etc.)
So i copied these librarys from /opt/cuda/lib64 to /lib64 and the install-process was succesfull.
But now i have system hangups btw. .. stability problems.. by using cuda client, - also with pyrit when cracking WPA/2 handshakes.
It's starting immediately. When i kill the process by hitting ctrl+c it's well, again. I also tried to change the process priority with nice.
I can't tell about CPU load. RAM is okay, no swapping. But the system load goes over 5.0.
And I really don't have an idea what to do.
Is this being a CUDA/Gentoo misconfiguration, or is it because of nvidia drivers?
~x86 version of the cuda-sdk tells me, that i have to downgrade nvidia-drivers.
I am using nvidia-drivers-190.42-r3 which is also needed by xorg-server-1.7.6.
GeForce 8800 GTS 512.

Sorry, i forgot: The dnetc (cuda-prerelease) client seems to use max. 30% CPU. But i don't know if it's true because of lacking stability.
Because of this, i thought it's a cuda thing..

Try cuda 3.1, and latest supported drivers for it. There's an ebuild for it on
