Single Threaded Workload - eviltoast

Yup. always gotta be that one single threaded program. In this case, appears to be frigate.

    Multithreading is almost impossible with only a few cores. It is barely enough to run Windows 🥺

    You should upgrade soon ☝🏻

    It’s mildly infuriating tbh but I understand it’s hard to implement threading for some functions.

    What actually infuriates me more is some AAA titles that specifically utilize 4 threads of my 3950x 32 threads cpu.

      Programming with threads is much harder than using a single thread.

      First your workload has to be split up in such a way that it can be distributed. That’s not always possible.

      The you gotta insert “synchronisation” to avoid a whole class of concurrency issues.

      Hence programmers always default to a single thread unless really needed.

        Of course - I get that. I’m a programmer myself.

        But it does have to be said that there’s little excuse for not doing it anymore for heavy applications, especially games. The tools/frameworks/engines have vastly improved, and people know (at least roughly) ahead of time what work is going to slog the CPU, especially in the case of a AAA studio.

        Note: I’m only referring to relatively modern games here - anything that’s older than when multithread really took off gets an automatic pass - it’s not reasonable to expect someone to cater for a situation that doesn’t exist yet.

          … Wut. You chose one of the best examples of where multi-threaded workloads are extremely difficult and often impractical as your example of where it should definitely be used…? 🤦

          Games are where it’s the most difficult, nevermind enterprise workloads that can be multi-threaded on paper, while games can often not even make that work in theory. Game workloads are incredibly, almost insurmountably, difficult to multi-threaded for most teams and studios.

          Not just from a technical standpoint but from a practical standpoint as well as you are significantly increasing the surface area for software defects, full of pitfalls and gotchas. Sure you can multi-thread your workload but now it actually runs slower than it would have if you never did this at all due to increased resource usage as a result of synchronization…etc

          Games like factorio are rarities, where the developers had both a small game and scope, and all the time and resources they needed to produce multi-threaded solutions to their workloads. Engines like unity have ECS, which has limitations of use and comes with extra asterisks. But outside that and a few other examples actual multi-threading is a massive undertakings that may actually mean your Game cannot be delivered.

            Difficult, yes. Impractical? Absolutely not, at least with some planning ahead. It’s not trivial (and I never said it was) but it’s getting both easier and more important every year.

        I’m programmer myself and I understand that it’s not simple even though you can use blocking or protected collections.

        I’m referring to a situation where the programmer made a function multithreaded but hard coded creating only 4 threads “to fully utilize a 4 core cpu”

      Heh. Classic case of being able to market your product as being “multithreaded” because is uses 2 threads? :P

        “The garbage collector runs in a second thread! This means we’re fully multithreaded now! Ship to customer and advertise multithreading!”

      I know your pain. Although, my gaming PC is only rocking a Ryzen 7 5800x. Not, nearly as many threads… but, there are a ton of games which are only using a small fraction of the available CPU.

      If I recall, Assassins’ creed was pretty bad about it… Minecraft (Especially modded) was horribly single threaded. And- more.

          Apologies then, its harder to sense sarcasm here on lemmy… when people are 100% serious about going around and vandalizing cars, because people have them… (Not- joking…)

    Xeon gang in the house. I picked up an HPE with an E5-2650 v4 on eBay with 64GB memory and some spinning disks for $180. Best investment I have made. It’s the z640 tower so pretty quiet and doesn’t need a rack. Core count has made my life a whole lot easier.
