Hi Aziz
-openmp 4 will speed up the recon of a single subject. If you had 16
processors and enough RAM you could run 4 subjects at the same time that
way and each of them would be faster. We've had recons complete in 2-3
hours this way, depending on the anatomy.

Hi Bruce,
So, I am not sure if I understand correct. Suppose, I would like to run 4
subjects simultenously, I have
to run the recon-all command of each subject on each terminal with -openmp.
Otherwise, is there any
other options to run 4 subjects in one terminal.
Thank you,
Aziz.

yes it does, and it should significantly reduce execution time unless you
don't have
multiple cores

Hi Bruce,
Does FS6 support the 'openmp 8' flag? I tried to use this flag with
'recon-all
-all' on FS6, but it took
longer time for only one subject.
Thank you,
Aziz.

Hi Aziz
with multiple course you can specify -openmp 8 for exmaple to
use 8 cores,
which speeds
things up a lot. It also depends how many recons you will be
running at
the same time. A 16
core machine with 64G of ram would be able to run 4 recons in
a few hours
each.

Hi experts,
I would like to find a new high-performance computer to
run the
reconstruction
process in Freesurfer.
Currently, I used a single computer (Intel core i7, RAM
8MB) to run
the commands
(e.g., 'recon-all -all'
) that spent average time 7-9 hours per one subject
data.
Please let me know what the best spec of the computer
that can
reduce the time
to 2-3 hours (if
possible).
Thank you,
Aziz
