I'm definitively a noob with both freesurfer and SLURM processes and I wonder if anyone could give me some advice. 

I tried processing a subject (including hippocampal segmentation) using the following command (freesurfer 6.0.0):

recon-all -all -s s03 -hippocampal-subfields-T1

It took nearly 12h to process. 

I then submit this job to a supercomputer (using slurm) and I asked for nearly 30Go RAM

It took nearly 7h to process. That seems good but I wonder if it's possible to speed it up a little more?

Regards,
