What? General computing as in supercomputers? https://www.fujitsu.com/global/about/innovation/fugaku/ https://www.fujitsu.com/global/about/innovation/fugaku/ Apple’s entire Mac lineup is going to be Arm-powered by year end too. Cost comparison is almost useless in this market because there simply are not enough wafers to meet demand. The price per core per watt is the real world comparison, and my inaudible MacBook fan demonstrates that beautifully.

TOP xx supercomputers are not general computing. The software stack basically doesn't matter because everything is going to be custom anyway. That's why you see custom ISAs, funky ISA extensions, one-off accelerators and single-purpose operating systems in them. None of that would fly for commercial applications.

    Linux isn't an operating system. There are many single-purpose operating systems built with Linux though, which is why I think the parent comment is still correct. As I'm sure you can imagine, those machines are multiplexed into hundreds or thousands of containers, VMs and supervisor kits, and those are definitely designed to run extremely niche containerized software or specialized distributions.

      > Linux isn't an operating system. While some of those VMs may be running trimmed down OSs tailored for their individual workloads, the fact remains they are all running under some sort of GNU/Linux or, at least, relying on the services of a Linux kernel. Now that you mention it, WSL1 should be called GNU/Windows instead, because it's the GNU userland on top of a Windows kernel with Linux lipstick.

  There was a time when people were sceptical about patches to get Linux running on those little 32 bit microcontrollers.
