Is CUDA in installed correctly on my Ubuntu 10.04? Some samples don't run.

I am trying to install CUDA on a server running Ubuntu 10.04.

I followed the NVDIA instructions and installed the "CUDA toolkit for Ubuntu Linux 10.04", "GPU Conputing SDK code samples",and "Developer Drivers for Linux (260.19.26) (64 bit)", my system is 64 bit. This installation seems successful. everything downloaded from http://developer.nvidia.com/object/cuda_3_2_downloads.html#Linux

According to the messages of the installation packages, I added /usr/local/cuda/bin to PATH, /usr/local/cuda/lib64:/usr/local/cuda/lib to LD_LIBRARY_PATH

Then, I tried to run the sample programs. The strange things is, some of them can be run, and some of them don't even through they can be made with no problem.

For example,
- convolutionSeparable will just stop there without any message, I can kill it by ctrl + c.

What is wrong with this?! How can I check if my CUDA installation is successful ? What is wrong with those programs don't run? They don't even have a error message.

I have similar problem but solved by updating kernel and drivers.

install newer kernel on 10.04

linux-image-generic-pae-lts-backport-natty
linux-headers-generic-pae-lts-backport-natty

download the latest nvidia driver from http://www.nvidia.com/Download/index.aspx?lang=en-us

install the latest CUDA (at moment 4.0) from http://developer.nvidia.com/cuda-toolkit-40

CUDA Toolkit for Ubuntu Linux 10.10     32-bit
CUDA Tools SDK  32-bit
GPU Computing SDK code samples

then I passed all SDK example tests.

I would start by upgrading the driver to 260.19.36, which can be found here. Then I would suggest running nvidia-smi -a to see if the driver is happy. Then I second the suggestion to run deviceQuery to see if the CUDA Toolkit 3.2 is working.

If deviceQuery output appears nominal, then I would start adding printf's to see where things go awry in matrixMul.

What does deviceQuery say? Also check the output of dmesg right after you run that program to see if you can figure out whats up.

Another tip, if you still are having issues, is try running: 

strace ./deviceQuery 2> out.txt

Then check out.txt to see if you can find any clues why this error is occuring.
