It appears that fressurfer 5.0 is compiled against cuda 3.2.x rather than cuda 4. Is there any workaround to force freesurfer 5.0 apart from recompilation for it use cuda 4.0. AS the latest version of the nvidia driver has change cuda version from 3.2 to 4.0.

That's odd - drivers are supposed to be backward compatible. Short of recompiling, I don't know of a workaround (and we don't have CUDA 4.0 installed here yet).

I have also installed cuda 3.2 with the same results. There might be an error in CUDA Error in file 'devicemanagement.cu' on line 46 : invalid argument. which I got when I used the latest nvidia driver with cuda 3.2 Could anybody on this list try freesurfer with cuda and the latest nvidia driver.

Are you able to try with the 3.2 driver? You might have uncovered a place where NVIDA isn't getting its backwards compatibility right.

Hi
I have tried with driver 260.19.36 with a similiar result. The complain in this case is that MRISallocCudaVertices: cannot allocate device memory !: all CUDA-capable devices are busy or unavailable.
