Hi Rick,
Thanks for the feedback. It makes sense regarding no major differences between AMD vs Intel.
In terms of RAM my question it was not 4GB total per node but 4GB/physical core/node. Since a dual socket node with 52 cores (intel 6230R x2) that would be 208 GB ram which is doable if we need 4GB/core/node. If I go with AMD which is 128 cores (64 cores x2 cpus) this would be 512GB which is much more expensive. I wanted to get a sense if AFNI has any hard or soft rules when it comes to ram per core since we would launch several jobs in parallel so I wouldn't be using all of the ram to run a single subject. I hope this clarifies my question a bit more.
Best,
Ajay
