Yes, you can have too many CPU cores - Ampere's 192-core chips break ARM64 Linux kernel in two-socket systems, company requests higher core count support (www.tomshardware.com)

I agree, they are just going to hit the wall again way too fast. If the limit is 256 or 2^8, they should increase it to 65536 or 2^16. Now that's a limit that feels safer to leave at for many year to come.

Or do what ietf did "We're running out of 32bit addresses, should we add some bits and call it an even 48? No! Let's double the number of addresses 96 fucking times!"

Start using 128bit for everything.

If you have to solve a problem, do it in a way that solves it for good.

Max value of uint128 is ~340 undecillion (~3.4e38).

Is it fair to assume that those are more cores than there ever has and will be made?

[–] gravitas_deficiency 1 points 9 months ago

Honestly, I think so.
