Dear AFNI experts:
I am designing a new neuroimaging cluster and wanted to see if there is a recommended RAM to core recommendation for AFNI. Generally I have purchased systems with 4GB ram per core but the current core count on this new system is about 52-64 cores per node (hyper threading disabled) so I am wanted to get more feedback as that can be a pricy endeavor. Is there a recommended minimum amount of ram/core to optimally run AFNI openmp versions?

Additionally, while I plan on using a docker to run AFNI, I am wondering if there is a strong potential for differing results between AMD based systems and Intel based systems. One of the existing clusters runs on Intel based processors (6230R) and so I wanted to make sure there are no issues in terms of reproducibility if we went with AMD vs Intel for this new cluster.

Thanks in advance for your help.

Ajay
