    Some modern workloads can take advantage of multiple computers. You can usually compile using things like distcc and spread the load across them.

    If you make them into a Kubernetes cluster you can run many copies or many different things.

    It’s still an unsolved problem: we still end up with single core bottlenecks to this day, before even involving other machines altogether.

    • Yes. It’s always the bandwidth that’s the main bottleneck, whether CPU-Memory, IPC, or the network.

      Screw quantum computers; what we need is quantum entangled memory sharing at a distance. Imagine! Even if only within a single computer, all memory could could be L1 cache.

        There is no action at a distance in quantum mechanics, that is a laymen’s misconception. If there was, it would not be compatible with special relativity, but it is compatible as they are already unified under the framework of quantum field theory. The No-communication theorem is a rather simple proof that shows there is no “sharing at a distance” in quantum mechanics. It is an entirely local theory. The misconception arises from people misinterpreting Bell’s theorem which says quantum mechanics is not compatible with a local hidden variable theory, so people falsely conclude it’s a nonlocal theory, but this is just false because quantum mechanics is not a hidden variable theory, and so it is not incompatible with locality. It is a local theory. Bell’s theorem only shows it is nonlocal if you introduce hidden variables, meaning the theorem is really only applicable to a potential replacement to quantum mechanics and is not even applicable to quantum mechanics itself. It is applicable to things like pilot wave theory, but not to quantum theory.
