I'm running poclbm on Linux with an Nvidia GTX 280.
The first time I ran poclbm, it was using a pyopencl that I had compiled with the includes and libs from the latest Nvidia Cuda SDK.

poclbm seemed to work, but I was getting 100% CPU usage.

Thinking that it was the pyopencl that I had compiled, I installed the pyopencl package from the Ubuntu repositories.
So now I have both a "make installed" pyopencl and the Ubuntu pyopencl, could that be part of the problem?
Still 100% CPU usage.

My Nvidia driver is the latest from the X-swat PPA.

Any way to fix this 100% CPU usage problem? It doesn't happen on this machine under Windows.

I am getting a similar problem. I have an 8800 GTS 640MB. Under windows I got 100% cpu usage with poclbm but all my programs were responsive. Under ubuntu I get 100% cpu usage but all my other programs are not responsive.
