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

Core counts for ARM-based server CPUs are overwhelming Linux operating systems.

Oops all cores

    These high power arm chips are really interesting. I feel like this is a good problem to have.

    I bet someone at some point said “256 is futureproof”. We’re well into Amdahl’s Law at this point.

      From the article:

      Back in 2021, a patch was sent out proposing the ARM64 CPU core limit be increased to 512, but Linux maintainers denied it because no CPU hardware was available at the time with more than 256 cores.

      The question is how long will that many cores stay niche though?
