> There is a reason that multicore cpus do not look like networked machines. Wait, what? I'm looking at an image of an unlidded Zen 2 CPU right now and it's a bunch of discrete compute devices surrounding a switch. Inside these devices are multilevel caches, just like real world network systems. The central "chiplet" multiplexes access to external buses over multiple serial PCI lanes; any network engineer would would recognize this pattern as trunking. All of this looks exactly like a network.
