Re: [Freesurfer] -openmp vs -threads, -parallel options in recon-all

I think it will be threads.

Thanks.

Just to confirm, the openmp reflects threads and not cores? In other words, on we have a 4 core machine with hyperthreading, so with 4 cores we have 8 threads available.

In that scenario, would the -openmp 4 option reflect 4 cores/8 threads or just 4 threads.

Thanks again.
