Hi,
I have the exact same error when running bedpostx_gpu on a NVIDIA tesla card with cuda 5.5. I installed it on a centos 6.5 computer though. Previously I had tested bedpostx_gpu successfully on debian wheezy after downloading from neurodebian. It took a while and a simple modification to make it work, but it worked on a laptop with debian. I start wondering if it has to do with centos. Unfortunatelly I have to have centos because of some other hardware.
I run cuda samples with success on the centos machine. For instance "devicequery" works. A Tesla card has no graphic output so I would have expected it to have no conflict with graphical driver. But as far as I have understood we need the nvidia graphical driver to be installed in order to use cuda. Then I assume (but I am not sure since I am no expert in graphical devices) that we should not declare the nvidia driver in xorg.conf. Is that correct? (or should I run nvidia -xconfig?).
Anyway the way to install cuda has slightly changed now since you don't need to download the driver before. Cuda toolkit will ask you if you want to do it. Maybe something goes wrong there.
I am sorry if I bring more confusion than solutions but I had the exact same error this week when I got the Tesla card and I have had many thoughts since then about what can have gone wrong.
Thank you,
Jonathan

It should not be a temperature problem unless your GPU has a hardware problem. Any video game increases the temperature of the GPU more than bedpostX.
Have you tried to run some CUDA samples from the toolkit ?
You can check the temperature and the memory being used every second by doing:
nvidia-smi -l 1
(you can do in a new terminal while Bedpostx is running).
Then, you can see if the process is close to the memory limit.
Could you share the output directory ?
Moises.
