Hi Ramesh, I do not know if you have considered this at all but I at least wanted to bring it to your attention. If you have please disregard.
I've been doing I.T. for over 20 years and the Nvidia card you have listed is the Geforce 610 concerns me that all of the effort you're going through won't be worth it in the end. It is several years old, released in May of 2012, and is a very basic card. I would be surprised if the CUDA code path runs quicker than your CPU because, even when it was released, it was the lowest end card of the 600 series. Unless you have a higher end Nvidia card, such as the 970, 980, 1060 (or higher) your CPU will very likely be faster in the recon-all process. Best, Peter ________________________________ From: freesurfer-boun...@nmr.mgh.harvard.edu [freesurfer-boun...@nmr.mgh.harvard.edu] on behalf of Ramesh Babu [mgrameshbabu2...@gmail.com] Sent: Wednesday, May 24, 2017 3:51 AM To: Freesurfer support list Subject: Re: [Freesurfer] cuda-gpu problem Dear Richard, This command recon-all -all -i grp237_t1.nii -s grp237 -sd grp237 -use-gpu -itkthreat 4 took 5.18 hrs and recon-all -all -i grp237_t1.nii -s grp237 -sd grp237 -use-gpu -openmp 4 took 4.69 hrs without any error. Thank you very much for your suggestions.
