no sure about that error, but clearly we need to look at that devicemanagement.cu code as it seems to be the gate keeper to getting anything running.
we'll see if we can get that code to produce some useful error message and post a new _cuda tarball.

Hi:
I installed the latest NVIDIA driver (256.44) in my DELL Precision T3500 (Quadro FX-580 graphic board, Ubuntu 9.04)... Then I installed CUDA Toolit 3.1 (for Ubuntu 9.10)... Then, I restart my computer... I tried to process a study with the freesurfer command:
"recon-all -autorecon1 -s ingrid -use-gpu",
but I got the error:

How can I find a solution to that problem ?...
