Is the most popular operating system for super computers?

Linux has completely dominated the supercomputer field since 2017, with 100\% of the top 500 most powerful supercomputers in the world running a Linux distribution. Linux is also most used for (web) servers, and then most often Ubuntu used, the most common Linux distribution.

What OS do supercomputers run?

Linux operating system
Although most modern supercomputers use the Linux operating system, each manufacturer has made its own specific changes to the Linux-derivative they use, and no industry standard exists, partly because the differences in hardware architectures require changes to optimize the operating system to each hardware design.

What OS do mainframes use?

z/OS
The only operating system choices for IBM mainframes were systems developed by IBM itself: first, OS/360, which was replaced by OS/390, which was superseded in the early 2000s by z/OS. z/OS remains IBM’s mainstay mainframe operating system today.
