I’m pretty sure those multi-million-node Linux supers that fill the
top of the Top500 list have a NUMA-style memory-addressing model.

You are wrong.
Last ccNuma was pushed out of top100 more than a decade ago.
All top machines today are MPP or clusters.
Not that a diffference between the two is well-defined.

After consulting Wikipeadia, it's probably far more than a decade.
The last one that I thought to be ccNuma, was in fact a cluster of
10 ccNuma computers.
