Yeah, I'm no kernel developer, but I've been replying to anyone saying 'just stick n * M1 in it' that even AMD has been trying to move back to more predictable memory access latency, less NUMA woes.
- freeone3000 6y agoBut in general we're moving toward even less uniform memory, with some of it living on a GPU. NUMA pretended that all memory was the same latency, because C continues to pretend we're on a faster PDP-11, but this seems like a step in the wrong direction as for how high-performance computation is progressing.
