Why do all supercomputers in the world use linux?
In: Technology
Super-computers are highly specialized to operate on sets of data. The original “super” computers from companies like CDC and cray had custom operating systems.
These days the Linux kernel is free and provides all the basic IO functions needed. By using this super-computer vendors only have to write drivers and custom software while letting the Linux kernel handle all the plumbing.
It is simply cheaper and more-efficient to use a well known foundation instead of reinventing the wheel every time.
