CUDA on Ubuntu?

I'm trying to get CUDA working on my Dell D630 running Ubuntu Jaunty. It has an Quadro NVS 135M and version 180.44 of the Nvidia drivers. I upgraded to version 6.6.36 of the Boinc client software but it still says "No CUDA devices found" in the Messages tab when it starts up. Maybe I need a newer Nvidia driver?

Thanks,
Chuck

____________

check the list of cuda device. it has to be a 8 series or up

The Quadro NVS 135M is listed as a CUDA-enabled card and I do have 256MB of memory on mine:

Looks like maybe you have to install the beta Nvidia driver version 190.18 to get CUDA support on Ubuntu...

you may have to run a 3rd party app. I don't see the 6.08 listed for linux. I think Lunatics has one for linux

i think you will find, if you have 256mb vidram and this is also your desktop display card you may not have enough vidram to run cuda. i had a 256mb card that was always out of memory for cuda. that however should not stop boinc from recognizing it.

i shouldnt think you would have to use the 190x driver. i use 185.18.31 just fine on linux. os type should not matter other than matching the arch (32 or 64bit) (or running the cuda 2.3 toolkit then you need the 190x driver). what you do need is to download the nvidia-toolkit (i prefer v2.2) and install that and copy the libs into the project directory and the libcudart files into the main boinc directory making sure ldconfig knows where they are and it has been run. then download the matching cuda application from lunatics and install an app_info.xml with it. make sure you have the use_all_gpus set to 1 in cc_config.xml

<options>
<use_all_gpus>1</use_all_gpus>
</options>


and in the project directory a 'number_of_gpus' file containing a 1 i forget what boinc version started using that but i believe 6.6.36 does use it.

i had trouble with cuda v2.3 and i am unclear if it is downward compatible or not. for me, going back to 2.2 solved everything. being fair, 2.3 does work for most people so it is your choice you just have to match the cuda app with the toolkit version.

skildude is correct there still is not a linux app available in the download stream from seti (at least none i have been able to find). however lack of this will not stop boinc from recognizing your cuda device and reporting it in the message log.

if all of the above is proper, boinc *shoud* report it in the log and should 'just work'.
