I think you missed that part of my original post: no X. This box has two Tesla GPUs, and my users are using them for heavy duty scientific computing.... And my problem is that neither their programs, nor the utility I use (I *think* it that it seems to be part of the CUDA toolkit
I didn't set that part up) can enumerate them... meaning that they can't see or use the GPUs.
what is the error? For example if I run "CUDA Device Query" (example from cuda toolkit) I get the following error if the kernel module is not the version needed for the compiled version of cuda program (cuda toolkit 5.5 and nvidia kernel module 310.19 - installed from nvidia.com)
I'm not sure what he's getting, but if I run enum_gpu, I get invalid device ordinal in enum_gpu.cu at line 23, which seems to be in the code for that (cuda by example, chapter 3?) HANDLE_ERROR( cudaGetDeviceCount( &count ) );

#./deviceQuery ./deviceQuery Starting...
CUDA Device Query (Runtime API) version (CUDART static linking)
cudaGetDeviceCount returned 35 -> CUDA driver version is insufficient for CUDA runtime version Result = FAIL
