Linux Now Runs On 99.6% Of Top 500 Supercomputers

Linux rules the world of supercomputers

Brief: Linux may have just 2% in the desktop market share, but when it comes to supercomputers, Linux is simply ruling it with over 99% of the share.

Linux running on more than 99% of the top 500 fastest supercomputers in the world is no surprise. If you followed our previous reports, in the year 2015, Linux was running on more than 97% of the top 500 supercomputers. This year, it just got better.

This information is collected by an independent organization Top500 that publishes the details about the top 500 fastest supercomputers known to them, twice a year. You can go the website and filter out the list based on country, OS type used, vendors etc. Don’t worry, I’ll do it for you to present some of the most interesting facts from this year’s list.

Linux got 498 out of 500

If I have to break it down in numbers, 498 out of the top 500 supercomputers run Linux. Rest of the two supercomputers run Unix-based OS. Windows, which was running on 1 supercomputer until last year, is nowhere in the list this year. Perhaps, none of the supercomputers can run Windows 10 (pun intended).

To summarize the list of top 500 supercomputers based on OS this year:

  • Linux: 498
  • Unix: 2
  • Windows: 0

To give you a year wise summary of Linux shares on the top 500 supercomputers:

  • In 2012: 94%
  • In 2013: 95%
  • In 2014: 97%
  • In 2015: 97.2%
  • In 2016: 99.6%
  • In 2017: ???

In addition to that, first 380 fastest supercomputers run Linux, including of course the fastest supercomputer based in China. Unix is used by the 386th and 387th ranked supercomputers also based in China.

Some other interesting stats about fastest supercomputers

List of top 10 fastest supercomputers in the world in 2016

Moving Linux aside, I was looking at the list and thought of sharing some other interesting stats with you.

  • World’s fastest supercomputer is Sunway TaihuLight. It based in National Supercomputing Center in Wuxi, China. It has a speed of 93PFLOPS.
  • World’s second fastest supercomputer is also based in China (Tianhe-2) while the third spot is taken by US based Titan.
  • Out of the top 10 fastest supercomputers, USA has 5, Japan and China have 2 each while Switzerland has 1.
  • US and China both have 171 supercomputers each in the list of the top 500 supercomputers.
  • Japan has 27, France has 20, while India, Russia and Saudi Arabia has 5 supercomputers in the list.

Some interesting facts, isn’t it? You can filter out your own list here to further details. For the moment I am happy to brag about Linux running on 99% of the top 500 supercomputers and look forward to a perfect score of 100% next year.

While you are reading it, do share this article on social media. It’s an achievement for Linux and we got to show off :P


  1. This is like saying that Honda has some of the best cross country and rally cars (BTW, this is just a hypothetical), and it makes you feel a little bit better driving a lowly Honda Civic. It’s just circle-jerking.

      • Speed has never been an issue for Linux. The desktop environment will never be what Apple or Windows offer. I am a Linux administrator, it’s my life all day. The productivity suites and applications just do not exist and most likely Linux will never thrive as a daily desktop. Thunderbird is still really all we have for email and it’s 2016.

        • Linux isn’t the top choice just for speed, but stability and security. Windows is a security sieve. Now sure why you guys can’t appreciate this dominance, instead have to be nit picking debbie downers. Maybe you’re Window shills, whatever. #Linux

    • Not really. That’s a highly inaccurate comparison.

      Super computers run big IT businesses and heavy scientific research (if you don’t get the importance of that, just stop reading), whereas “rally” cars can explode and the world won’t really miss them.

      Google, Facebook, Amazon, Reddit, Wikipedia etc. run on top of Linux. Android is Linux-based. Oracle maintains a distribution.

      Your analogy is plain false when actual utility is at stake.

      If you googled whatever today, no matter what OS your amateur device is on, you used Linux. It’s a big part of our lives.

      Besides, you probably can’t acknowledge the fact but Linux fits all common pc needs.

      I’ll never buy anything from Apple or MS again in order to accomplish simple tasks (office stuff, basic image/video editing and so on).

      Linux can be used on a “normal” PC on a daily basis by anyone who isn’t a hardcore gamer.

      Also, as a developer, I can’t really imagine going back to Windows.

      I use windows for gaming ONLY and occasional .NET development, although I started using VS Code on Linux for that matter and I’m currently figuring out how to replace IIS for good.

      Steve, who still uses email clients on PCs for god’s sake?

      Alright pals, see ya :P
