I'm running SUSE Linux Enterprise Server 11 SP1 64-bit and have two NVIDIA Tesla M2050 cards installed. They show up in YaST2 like this:

─┬─Display                                                                
 │ ├+─GD 5446                                                               
 │ ├+─nVidia 3D controller                                                  
 │ └+─nVidia 3D controller 

When I start BOINC, though, it does not detect the CUDA cards:

BOINC seems to see only the Cirrus video controller:

host:~ # lspci | grep VGA
00:02.0 VGA compatible controller: Cirrus Logic GD 5446

It looks like the correct drivers are installed:

What do I need to do to allow BOINC to recognize and utilize the CUDA cards?

BOINC client version 6.2.18 for x86_64-pc-linux-gnu

Is nothing newer available for your distro? CUDA detection started only from 6.4.5 onwards, ATI detection from 6.10 onwards.

You will probably also need videocard drivers from the GPU manufacturer, nVidia CUDA 2.0 - 177.35 and above.

Edit:
Installed driver version is 290.10, according to /sbin/modinfo nvidia

CUDA detection started only from 6.4.5 onwards, ATI detection from 6.10 onwards.

Aha, that must be it! Thanks for the info. I'll download a newer version directly from here.

Yes, that did it. Thanks again. Not sure why the BOINC version in the YaST repository is so outdated.
