External Email - Use Caution Hi Ajay
The memory footprint of each pipeline is something I wish there were better records of! You're right that 4GB is outdated. It really depends on the pipeline. For cross-sectional recon-all, 20Gb should do it. For longitudinal pipelines I suspect (but haven't confirmed) that the RAM footprint is related to the number of timepoints a subject has. The infant stream needs around 32Gb. Those are the ones I'm familiar with. Each command should have an fs_time output with a measure of the peak memory used, though it is not super accurate. -Paul On Mon, Jul 12, 2021 at 4:39 PM Ajay Kurani <dr.ajay.kur...@gmail.com> wrote: > External Email - Use Caution > > Hi Freesurfer Experts, > I am designing some new hardware for a mini-cluster running Freesurfer > and other neuroimaging toolboxes and wanted to better understand > requirements from Freesurfer. > > 1) Is there a minimum amount of ram per core that is needed/recommended or > is the amount of ram only defined per subject.
