Is this something you can actually configure on modern processors, or is it more hypothetical advice for future chip makers?

- vidarh 3y agoNo, it's not. For starters because it's new, and second it's not a given it'd be useful for CPUs at all. Caches are used in all kinds of places, not just CPUs. E.g. operating systems, content delivery networks, databases, reverse web caches. There's a huge number of places for different kinds of cache algorithms, and the tradeoffs that works best varies a great deal depending on workloads and requirements (e.g. whether worst case latency, average latecy, or hit rate, or any number of other factors matters most)
