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

Why would we call it “mini”? It is straight up NUMA.
- wmf 7y agoIt's not NUMA since the distance from all the cores to main memory is the same (uniform).
- shereadsthenews 7y agoOh hrmm, my mistake. This is a welcome change from the older one.
- craz8 7y agoAlthough 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
- Dylan16807 7y agoDon'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.
