External Email - Use Caution
Hi Vasudev,
in case you use v6, you can use the -parallel flag to process the hemispheres
(and a few other things if I remember correctly) in parallel. Note that doing
so will parse the -openmp flag to all instances. E.g.
recon-all -all -openmp 4 -parallel -s subjID -i inputFile
Also the reduction in processing time using openmp is limited – I don’t recall
exactly if it was bound to the number of physical cores your CPU has or if it
was an upper limit to due the way the parallelization works (I have something
like in mind like not much of an increase beyond openmp 8).
Best,
Falk

Betreff: [Freesurfer] How to fasten recon-all execution time without using CUDA
External Email - Use Caution
Dear all,
I am using - openmp 30 to run recon-all, i see now change in the execution time
period.
Could you please highlight me a method to reduce the execution time for
recon-all, if possible some parallel script to do that same.
Thanks
Vasudev
