done… same problems as before. Mandelbrot again freezes the XServer. Just change the color, zoom and pan a little bit and the fun is over again (fast in every sense). The only positive thing is that with our programs we sometimes get an undefined launch failure instead of a hanging X. But in fact this does not make the situation much better…
The setup did not change except the 8800GTX as device 0 for display rendering of course. Mandelbrot was adapted in a way that cuda uses device 1 (the 280GTX) for calculations.
Any further suggestions? In my optinion everything still points to a bug within CUDA 2.0b2?
I played around with my 2 cards setup. It turns out that also the 8800 GTX freezes when Mandelbrot is compiled with CUDA 2.0b. It takes much longer till the XServer hangs but still it is an issue because the stuff should run longer than just a few minutes. I appended a log when a freeze happens with the Mandelbrot application with the 8800GTX as cuda device.
