Not to hijack your question, but I have similar questions. I have CUDA toolkit 3.1 installed, "cudadetect" returns: "Detecting CUDA... 32767 CUDA enabled device(s) detected." but, when I run recon-all, e.g.:
recon-all -subjid PC -all -use-gpu
I get the following errors at the mri_em_register_cuda step:
/lcn2/lesion_warp.dir/MAP3_Nifti/freesurfer_subs.dir/PC/mri
mri_em_register_cuda -skull nu.mgz /usr/freesurfer/average/RB_all_withskull_2008-03-26.gca transforms/talairach_with_skull.lta
mri_em_register_cuda: Command not found. Linux linux-lvmb 2.6.34-12-desktop #1 SMP PREEMPT 2010-06-29 02:39:08 +0200 x86_64 x86_64 x86_64 GNU/Linux
A quick peak in /usr/freesurfer/bin shows that there is no mri_em_register_cuda binary.
Are cuda binaries supposed to be bundled with the new 5.0 release, or are they created on the fly by FreeSurfer, or are they just plain missing? FWIW, I have CentOS 5 x86_64 version of FreeSurfer installed, running on OpenSuse 11.3

Hi!
I will like to try the beta CUDA support in 5.0. And I have some questions here
- Are all needed libraries bundled in the release? Or I need to go to
CUDA’s site to get those dependency? And if I need to, what are those dependency I need to grab and install? 2. I have RH 5 64 bit linux box with single NVIDIA FX card and macpro snow leopard box with dual NVIIDA GT 120. Does CUDA support work for both OS? If they do, any idea what the speed up will be??
