        How can there be N/A though? How can any functional computer not have an operating system? Or is just reading the really big MHz number of the CPU count as it being a supercomputer?

          Early computers didn’t have operating systems.
          You just plugged in a punch card or tape with the program you want to run and the computer executed those exact instructions and nothing else.
          Those programs were specifically written for that exact hardware (not even for that model, but for that machine).
          To boot up the computer, you had to put a number of switches into the correct position (0 or 1), to bring its registers in the correct state to accept programs.

          So you were the BIOS and bootloader, and there was no need for an OS because the userspace programs told the CPU directly what bits to flip.

          but it did not stick.

          Yeah. It was bad. The job of a Supercomputer is to be really fast and really parallel. Windows for Supercomputing was… not.

          I honestly thought it might make it, considering the engineering talent that Microsoft had.

          But I think time proves that Unix and Linux just had an insurmountable head start. Windows, to the best of my knowledge, never came close to closing the gap.

            But, surely Windows is the wrong OS?

            Windows is a per-user GUI… supercomputing is all about crunching numbers, isn’t it?

            I can understand M$ trying to get into this market and I know Windows server can be used to run stuff, but again, you don’t need a GUI on each node a supercomputer they’d be better off with DOS…?

              Oh yes! To be clear - trying to put any version of Windows on a super-computer is every bit as insane as you might imagine. By what I heard in the rumor mill, it went every bit as badly as anyone might have guessed.

              But I like to root for an underdog, and it was neat to hear about Microsoft engineers trying to take the Windows kernel somewhere it had no rational excuse to run, perhaps by sheer force of will and hard work.

                Where did you find that azure runs on linux?

                I dont know of anywhere that Microsoft confirms, officially, that Azure, itself, is largely running on Linux. They share stats about what workloads other are running on it, but not, to my knowledge, about what it is compared of.

                I suppose that would be an oversimplification, anyway.

                But that Azure itself is running mostly on Linux is an open secret among folks who spend time chatting with engineers who have worked into he Azure cloud.

                When I have chatted with them, Azure cloud engineers have displayed huge amouts of Linux experience while they sometimes needed to “phone a friend” to answer Windows server edition questions.

                Good question! I can’t remember.

                I think I read a Microsoft blog or something like a decade ago that said they shifted from a Hyper-V based solution to Linux to improve stability, but honestly it’s been so long I wouldn’t be shocked if I just saw it in a reddit comment on a related article that I didn’t yet have the technical knowhow to fully comprehend and took it as gospel.

        Apple had its current desktop environment for it’s proprietary ecosystem built on BSD with their own twist while supercomputers are typically multiuser parallel computing beats, so I’d say it is really fucking surprising. Pretty and responsive desktop environments and breathtaking number crunchers are the polar opposites of a product. Fuck me, you’ll find UNIX roots in Windows NT but my flabbers would be ghasted if Deep Blue had dropped a Blue Screen.

            I think it was PS3 that shipped with “Other OS” functionality, and were sold a little cheaper than production costs would indicate, to make it up on games.

            Only thing is, a bunch of institutions discovered you could order a pallet of PS3’s, set up Linux, and have a pretty skookum cluster for cheap.

            I’m pretty sure Sony dropped “Other OS” not because of vague concerns of piracy, but because they were effectively subsidizing supercomputers.

            Don’t know if any of those PS3 clusters made it onto Top500.

            The GUI is optional these days, and there’s plenty of Windows servers that don’t use it. The recommended administration approach these days is PowerShell remoting, often over SSH now that Windows has a native SSH server bundled (based on OpenSSH).

              That gives me the idea of windows server installed on bare metal configured as a lightweight game runner. (much like a linux distro with minimal wm)

              I’ve seen people using slightly modified windows server as an unbloated gaming OS but I’m not sure if running a custom minimal GUI on windows server is possible. You seem knowledgeable on the subject, with enough effort, is it possible?

            I’d say having a GUI is not inherently stupid. The stupid part is, if I understand it correctly, the GUI being a required component and the primary access method.

              Yeah. Thankfully, Windows server cleaned up that stupidity starting around 2006 and finished in around 2018.

              Which all sounds fine until we meditate on the history that basically all other server operating systems have had efficient remote administration solutions since before 1995 (reasonable solutions existed before SSH, even).

              Windows was over 20 years late to adopt non-grapgical low latency (aka sane) options for remote administration.

              I think it’s a big part of the reason Windows doesn’t appear much on this chart.

      Yes, in the linux stat. The otheros option on the early PS3 allowed you to boot linux, which is what most, of not all, of the clusters used.

      I think you can actually see it in the graph.
      The Condor Cluster with its 500 Teraflops would have been in the Top 500 supercomputers from 2009 till ~2014.
      The PS3 operating system is a BSD, and you can see a thin yellow line in that exact time frame.

      There’s no reason to believe smaller supercomputers would have significantly different OS’s.
      At some point you enter the realm of mainframes and servers.
      Mainframes almost all run Linux now, the last Unix’s are close to EOL.
      Servers have about a 75% Linux market share, with the rest mostly running Windows and some BSD.

      I wonder if the numbers are still this good if you consider more supercomputers.

      Great question. My guess is not terribly different.

      “Top 500 Supercomputers” is arguably a self-referential term. I’ve seen the term “super-computer” defined whether it was among the 500 fastest computer in the world, on the day it went live.

      As new super-computers come online, workloads from older ones tend to migrate to the new ones.

      So there usually aren’t a huge number of currently operating supercomputers outside of the top 500.

      When a super-computer falls toward the bottom of the top 500, there’s a good chance it is getting turned off soon.

      That said, I’m referring here only to the super-computers that spend a lot of time advertising their existence.

      I suspect there’s a decent number out there today that prefer not to be listed. But I have no reason to think those don’t also run Linux.

        They do use Ubuntu, Red Hat and SUSE mostly.

        Microsoft uses their own Linux distro now.

      Unix is basically a brand name.
      BSD had to be completely re-written to remove all Unix code, so it could be published under a free license.
      It isn’t Unix certified.

      So it is Unix-derived, but not currently a Unix system (which is a completely meaningless term anyway).

          It means nothing, it’s just a paycheck you sign and then you get to say “I certify my OS is Unix”. The little bit more technical part is POSIX compliance but modern OSs are such massive and complex beasts today that those compliances are tiny parts and very slowly but very surely becoming irrelevant over time.

          Apple made OSX Unix certified because it was cheap and it got them off the hook from a lawsuit. That’s it.

            Microsoft could technically get Windows certified as UNIX.

            I don’t think they could now that the POSIX subsystem and Windows Services for UNIX are both gone. Don’t you need at least some level of POSIX compliance (at least the parts where POSIX and Unix standards overlap) to get Unix certified?

      That’s certainly a big part of it. When one needs to buy a metric crap load of CPUs, one tends to shop outside the popular defaults.

      Another big reason, historically, is that Supercomputers didn’t typically have any kind of non-command-line way to interact with them, and Windows needed it.

      Until PowerShell and Windows 8, there were still substantial configuration options in Windows that were 100% managed by graphical packages. They could be changed by direct file edits and registry editing, but it added a lot of risk. All of the “did I make a mistake” tools were graphical and so unavailable from command line.

      So any version of Windows stripped down enough to run on any super-computer cluster was going to be missing a lot of features, until around 2006.

      Since Linux and Unix started as command line operating systems, both already had plenty fully featured options for Supercomputing.
