Hi,
I have been working on speeding up the the hippocampal segmentation in freesurfer 6 beta and I have been playing around with both -openmp and -use-gpu flags. I noticed that freesurfer does seem to make use of all the threads in freesurfer 6 irrespective of passing the -openmp flag or not. Is that the right behaviour. I found this by analysing the cpu usage in both the cases.
Also, it looks like development for GPU usage has been halted for now and so I was trying to use the CUDA 5 for getting it working under ubuntu 14.04. I have been not successful that as the cuda device isn't getting selected. Do you have any recommendations on that?
And lastly, there is the itkthreads option available to -hippocampal-subfields-T1, so can I combine all three or two of these options to minimize the execution time - like GPU and itkthreads or GPU, OPENMP and itkthreads?
Also the v6 beta is no longer available on your website. Is there any particular reason as to why it was removed and can I continue using the copy that I have for hippocampal segmentation ?
Thanks, Tyson
