• Back in the day, there was a distributed cluster OS called Mosix. Even back then I had several spare computers lying about, and the idea of being able to chain them all together and have one virtual computer that would automatically distribute processing without special coding was enticing. It turned out to not work very well unless you did specially code for it, or clustered the computers very tightly with fiber; it just wasn’t worth it.

    But when I see piles of compute like this, a part of my still wants to network them all together and run … well, whatever fills the shoes of OpenMosix these days, if anything does.

      Yeah, I’ve always wanted to do something like that. I’ve always got a bunch of computers running virtually idle and it would be nice if they could just help out with whatever your main PC is doing.

      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.
