If I were you I would check if you have enough power to drive the card.
Also I believe reading Lonni writing the OpenGL interop is a shady area since the T10P’s have had the 3D turned off on the card. Are non-OpenGL samples stable?
Personally I have a T10P without graphical out (and 8800GTX next to it for graphics), and I only had the Mandelbrot example lock up my system, N-body & particles were running fine. I’ll try alignedtypes on monday to see if I have the same problem.
Did you recompile with -arch sm_13 ? I think I did not do that.
I am running my machine with the T10P (no display connectors) and a Quadro FX1700.
I have also tried a Geforce 8800GT, but it makes no difference.
No luck with the 177.03 driver!
I made some progress with my simulation code by extensively using ThreadSynchronize().
For the small simulation examples the code works most of the times for the first run and maybe the second run, but in the third or fourth run it looks up the machine, blue-screens, or spontaneously reboots.
For the big simulations examples the code locks up during the first run after a couple of iterations in the algorithm.
I am getting errors like: “launch timed out and was terminated” before the machine locks up.
It seems that in the driver some bad stuff is accumulating and finnaly leads to the lock up.
Sometimes the simulation code stutters for a few iterations before it dies.
This behaviour is nearly identical under Windows and Linux.
If this problem is not confined to my card/machine you can easily reproduce this instability by running the CUDA SDK sample “alignedTypes”.
Just to add in some of my experiences with a T10P sample running on a headless Ubuntu Hardy box. I know Ubuntu is not supported, but thought this might be interesting for other users as well. I am running 177.10 on x86_64
The few test I have run seems to work okay, but the machine randomly locks up, even when not using CUDA. Typically the only trace of the error is the following line in /var/log/kern.log:
