Hi FSers, I have an Ubuntu machine (14.04 LTS) with a quad-core i7 4770k/32gb RAM and recon-all is taking me approximately 6 hours per subject without using openmp (haven't tried this yet). According to the terminal, it finishes without errors. I've read (e.g., https://surfer.nmr.mgh.harvard.edu/fswiki/FsQuizAnswers) and heard that recon-all should take 20-24 hours per participant to complete. So, should I be celebrating my 6 hour run time or should I be very suspicious of it?
Also, how does freesurfer go with hyper threaded CPUs? (as is the case with the 4770k; 4 cores, 8 threads). I've read that you should restrict parallel processing to one subject per core. Can I take advantage of the hyper threading and run 8 subjects simultaneously or should I be more conservative and only run 4? Cheers, Linden
