I suppose I'm not the only to experience "Blue screens" while
running stream programs.
The scenario is always the same:
(1) after some successful runs, the same call to a sequence of kernel treatments generates a stall in the GPU and after a while the driver
"automatically recovers from the device"
(2) The system although seeming to have recovered works for some more
minutes, and after a while ... here we go ==< boom; blue screen pops up
and reference to ATIKMDAG error is noticed on the dead screen
Over the past months, I found that:
- extending windows time_out (in register) helps to a certain extent... but not always...
- stopping ATIevent services seems to reduce the frequency of blue screens... but this doesn't fix the problem
Just to be precise, I'm running 20 times/second a serie of 10 kernels,
and typically the system breaks after 150 runs...
