First off let me thank all the people on this forum… your posts have been very helpful to me.
However now I seem to be stuck on a very difficult problem and cannot seem to solve it.
I am a former Windows user currently making the switch to open source for work.
I have :-
1.) Ubuntu 12.04 LTS
2.) Z87 OC Formula Asrock mobo
3.) 16 GB RAM
4.) NVIDIA GTX 660 Ti - 3 in number
5.) CUDA 6.0
When I use only one of the cards I can compile deviceQueryDrv and get it to run. However when I add the other 2 cards I get problems
CUDA Device Query (Driver API) statically linked version
cuInit(0) returned 101
→ CUDA_ERROR_INVALID_DEVICE (device specified is not a valid CUDA device)
Result = FAIL[/b]
And when I run deviceQuery I get a problem also
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 10
→ invalid device ordinal
Result = FAIL
Here are the details of my system
lspci | grep -i nvidia

Unable to determine the device handle for GPU 0000:03:00.0: Unknown Error
nvidia-settings -q NvidiaDriverVersion
Attribute ‘NvidiaDriverVersion’ (svamotive-desktop:0.0): 331.20
I have also modified /etc/X11/xorg.conf to include all three Device sections for the different Cards.
I still cannot get the system to work with all 3 of the GPU cards
Since this is for my work… I am kinda in a bind. Any help would be appreciated.
