Why would we call it “mini”? It is straight up NUMA.



It's not NUMA since the distance from all the cores to main memory is the same (uniform).


Although Threadripper 2990 is not uniform to main memory, which adds a wrinkle

So now there’s at least 2 levels of Non Uniform access to manage by the Bios/OS


Don't forget the CCX level, too.

The full list of varying latencies is something like: SMT, inter-core, inter-CCX, inter-die, inter-socket. And even that misses a few subtleties.


Oh hrmm, my mistake. This is a welcome change from the older one.
