@ACM@mastodon.acm.org That quote doesn't do justice to an illustrious man; it has wisdom, but it wasn't his particular insight. We knew that in the 1980s; everyone doing ultra-high performance parallel processing either knows it via received wisdom or else rediscovers it for themselves. It's just hard, both then and now, although thanks to Moore's law we can do far more in that direction today. But it's still very difficult and we are still far from any ideal solution.
