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. Most of the threads I found say you need a minimum of 4 GB ram but these were from a long time ago and may not apply to the OPENMP code. Our compute node will have between 52-64 cores so I wanted to know what is the ratio for Ram to CPU (multithreading turned off) that is recommended as opposed to Ram per subject. 2) AMD vs Intel We will run jobs on an existing cluster that has Dual Intel Xeon 6230R and for our new minicluster we are debating between AMD and Intel. While AMD offers higher core-count per CPU, I am worried that results could potentially differ based on the CPU/underlying libraries. We plan on using docker images so from your perspective do you have a recommendation ? Best, Ajay
