Hi Richards, Thanks for the very quick reply. Good to know that someone has successfully compiled GPU binaries for newer CUDA versions. I took a quick look at the developer's guide for building the cuda binaries from source, but it seems like a very involved process? Do your compiled binaries only work for CUDA SDK 7.5 or have you tested them with other CUDA versions?
Also, would you mind sending me an example binary (e.g. mri_ca_register_cuda) just so I cant test it myself and rule out whether this is just an issue with the way our GPU is configured? (I can't even get cudadetect to acknowledge my GPU as a cuda-enabled device (it just says 0 devices found), despite it successfully acknowledging that the GPU "exists") Please let me know and I cna send you a private email address. Thanks again for your help! And hopefully this thread will help others interested in updating their gpu-capabilities with Freesurfer. -Derek ________________________________________ From: freesurfer-boun...@nmr.mgh.harvard.edu [freesurfer-boun...@nmr.mgh.harvard.edu] on behalf of R Edgar [freesurfer....@gmail.com] Sent: Wednesday, June 22, 2016 3:46 PM To: Freesurfer support list Subject: Re: [Freesurfer] Any updates on recon-all GPU support?

I've successfully compiled and run mri_ca_register_cuda with CUDA SDK 7.5 (and a K1200 Quadro). I've also made a few performance tweaks, which have shaved another minute or so off mri_ca_register_cuda. If you're having trouble compiling from source, I can try to help, if you let me know where you're hitting trouble.
