NVIDIA has acknowledged that 2.0beta2 driver contains a bug: even for the secondary GPU watchdog is still active.
This problem is still not solved in the CUDA 2.0! Kernel terminates with “the launch timed out and was terminated” message (the only difference is that it works for a bit longer time now: 11-12 seconds instead of about 7 seconds).
This is really strange and annoying and it is crucial for many tasks (including mine), my kernel may need much more than 12 seconds.
What will NVIDIA guys say this time ?
Here is the thread with confirmation of the bug: Confirmation
