Re: [Freesurfer] implementation on Neurodebian

Bruce,

http://surfer.nmr.mgh.harvard.edu/fswiki/CUDADevelopersGuide#Benchmarks Found this link..clearly impressive, are these benchmarks for GPU enabled cards with CUDA or also with ATI Radeon GPU enabled cards?

Best, Cartik

Hi Knut, Good to know we can speed things up with CUDA. I have a multicore CPU and was wondering if there is a parallelized version of Freesurfer on the CPU. Thanks for the speedup! Best regards, Cartik On Oct 24, 2011, at 4:41 AM, Knut J Bjuland wrote:

 Hi Cartik

 You use -use-gpu to offload rendering to the GPU using cuda.
