The same could be said about windows on supercomputers. Why is windows supported so poorly by Cray and other HPC supercomputer vendors when Linux is supported so well? It is just about the demographics.

That is easy. Linux is technologically superior to Windows in every way.

  I think hyperbole is unnecessary here - Linux is superior in many ways, but your statement is only going to provoke arguments of exceptions.

Actually, MSFT has pushed Windows Server on supercomputers a few times, as well as for other latency critical applications like the London Stock Exchange. Each time they've ended up with egg on their faces for technical reasons, i.e. Linux consistently outperforms Windows Server both on speed and reliability for these workloads.

  Right, you're simply providing reasons that agree with me! I work as a tech guy (linux wrangler / code monkey) for a finance firm. I worked in finance during the meltdown of LSE and the new linux based "Millennium" platform. I agree with you that Linux consistently is higher throughput AND lower latency, but that is my point. Windows isn't on supercomputers because it isn't a great fit and there isn't much of a market for it. Ditto can be said for Linux on the Desktop. * This message brought to you from my RHEL7 work workstation running GNOME 3 and Chrome :D

This may be slightly off-topic (and it's admittedly an older incident), but the fiasco with the Aegis missile cruiser, the USS Yorktown, often comes to mind when I read of high-value or mission-critical systems using Windows of any kind. Sadly, the Yorktown is certainly not unique with respect to major projects relegated to using Windows OSes- it just happens to be a particularly vibrant example of the potential results. https://gcn.com/Articles/1998/07/13/Software-glitches-leave-Navy-Smart-Ship-dead-in-the-water.aspx https://gcn.com/Articles/1998/07/13/Software-glitches-leave-...
