@regehr@mastodon.social @steve@discuss.systems For example, it's a goddamn NIGHTMARE doing a high-performance memory subsystem for absolutely anything.
This whole "shared memory" fiction we're committed to maintaining is a significant drag on all HW, but HW impls of it are just in another league perf-wise than "just" building message-passing and trying to work around it in SW (lots have tried, but there's little code for it and it's a PITA), so we're kind of stuck with it.

@regehr@mastodon.social @steve@discuss.systems Basically almost everything that _all_ major ISAs pretend is true about memory at the ISA level is an expensive lie, but one that ~ALL the SW depends on. :)
