    #-Link-Snipped-# You are right on the part that most modern supercomputers use the Linux operating system. But you may see that each company makes its own specific changes to the Linux-derivative they use. Therefore, no industry standard exists, partly due to the fact that the differences in hardware architectures require changes to optimize the operating system to each hardware design.

    I think the primary reason behind using Linux could be that it’s open-source. They don't have to work from scratch because they can modify existing drivers.
    Other reasons could be that Linux has been used by millions of users, so it has best support and the widest selection of available software packages and libraries.

    I agree with above. Linux basically offers a lot of customization and it's basically a UNIX based system. No super-computer will use 'Linux' or its flavors without adding their own bit of customization to it.

    I doubt that's the consideration made while picking the operating system for Super Computers. It's of course not going to be uBuntu or kBuntu operating out of the box on any supercomputer; but Linux Kernels rewritten for the specific needs.

    Third, Virus free software
    Fourth, Wide selection of rpm packages & libs.
