Hello Vasudev, I think in January of 2018 it was possible to build the development branch of the freesurfer tree using cuda 5. But I believe that was the last version we tried building the source with. We no longer support building with cuda and instead favor using OpenMP.. Part of this is because of cuda’s dependencies on the Nvidia graphics hardware which is a moving target. Some vendors have essentially stopped supporting Nvidia graphics card drivers, e.g., Apple as of Mac OS 10.14 onward. The Freesurfer dev branch source is now compiled with C++ compilers, and I don’t know that anyone has tried building with cuda since we changed the compilers for freesurfer. - R.

Dear,
I tried running recon-all -s subjectname -t subjectid -all -openmp 15 , and it still runs very slowly. Is there a faster way to reduce the recon-all time using openmp, please kindly suggest me.
Thanks Vasudev

Hi Vasudev
what does "very slowly" mean?
