Hi Dan, Thanks. While I agree that all kinds of GPUs might be sufficient as far as the hardware and FS computations go, the drivers in fact make a major difference for visualizations. For my card the proprietary NVIDIA drivers turned out to be 10-20 times faster than the CentOS 6.5 Noveau

Hi Tommi, That is true, but it is also the most extreme comparison possible. A crude estimate of the ranking of drivers would be: NVIDIA Intel (these are open source by default) AMD radeon (open source amd) Nouveau (open source nvidia) While both NVIDIA and AMD hardware are of similar speed

Hi, Is there a FreeSurfer/MNE (maybe even FSL, TrackVis) recommendation to use the noveau drivers that come with CentOS 6.5 or would it be better to go with the proprietary drivers from NVIDIA? I would imagine that since FS 5.3 does not use GPU for analysis, this is mainly relevant for

Tommi, Here at the Martinos Center we use the proprietary drivers from NVIDIA. We have no reasons to believe the Nouveau drivers would work better, but that isnt to say one doesnt exist. -Zeke On 08/22/2014 03:23 PM, r...@nmr.mgh.harvard.edu wrote: Hi, Is there a FreeSurfer/MNE (maybe

Just to add. If you are not using the CUDA options (which in my understanding aren't being updated anyway), I find that the gpu included in modern Intel cpus is more than sufficient for my FreeSurfer and MNE uses. HTH D On Fri, Aug 22, 2014 at 4:15 PM, Z K zkauf...@nmr.mgh.harvard.edu wrote:
