They are exactly the same. The two flags go to the same code. ________________________________ From: freesurfer-bounces@nmr.mgh.harvard.edu freesurfer-bounces@nmr.mgh.harvard.edu on behalf of d m fmrilog@outlook.com Sent: Wednesday, November 18, 2020 5:59 PM To: freesurfer@nmr.mgh.harvard.edu freesurfer@nmr.mgh.harvard.edu Subject: [Freesurfer] -openmp vs -threads, -parallel options in recon-all
External Email - Use Caution
Hello,
What is the difference between the -openmp and -threads option for recon-all?
Do they reflect the same thing: Number of threads used concurrently?
If we want to use 10 threads for the recon-all command, which option should we use? -openmp or -threads? How does this relate to the -parallel option?
Does every part of recon-all use multi-threading or only does only a subset of parts within recon-all use multi-threading?
Thanks in advance.
