Hi Ryan,

node distances:
node 0 1
0: 10 20
1: 20 10

Whereas I assume the Graviton3 has 64 CPUs (cores) flat in a single MC
domain? I guess topology has influence in benchmark numbers here as well.

I can't easily enable scheduler debugging right now (which I think is needed to
get this info directly?). But that's what I'd expect, yes. lscpu confirms there
is a single NUMA node and topology for cpu0 gives this if it helps:

If you dump /proc/schedstat it should give you topology info as well.

(you will need to parse it depending on which CPU you are looking this from)
