Hi all,

I am still working on this problem. Does anyone know if Freesurfer is asking for CUDA 5.0, except that I have CUDA 6.0 installed?

My next steps will be to find out if Freesurfer is calling an older version of CUDA that isn't installed, or trying the CUDA samples. I really want to get this to work.

Hi,

I'm fairly novice at Linux and I've been trying to setup CUDA for recon-all. I get an error as follows:

[TLA@COGMOB-linuxPC ~]$ recon-all -s bert -use-gpu -openmp 8 Testing for CUDA device: /usr/freesurfer/bin/mri_em_register_cuda: error while loading shared libraries: libcudart.so.5.0: cannot open shared object file: No such file or directory Linux COGMOB-linuxPC 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

recon-all -s bert exited with ERRORS at Fri Jun 27 10:53:29 PDT 2014

For more details, see the log file To report a problem, see http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting

Any idea what is going on? I setup CUDA and my Nvidia drivers according to this tutorial (http://aspratyush.wordpress.com/2012/05/06/install-nvidia-cuda-on-centos-6/). With, of course some slight changes to install the latest toolkit.

Thanks in advance,
