The main reason for this growth is the open source nature of Linux. … Linux, on the other hand, is free and easier to customize. Engineering teams can easily customize a Linux-based operating system for each of the supercomputers.
Do supercomputers run Linux?
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.
Why does Linux dominate supercomputers?
She sees Linux as tightly linked to supercomputing because it provides the scale and flexibility to support high-performance computing and exascale computing systems – those that are capable of calculating at least 1,018 floating point operations per second (1 exaFLOPS).
Why we are using supercomputers?
Common applications for supercomputers include testing mathematical models for complex physical phenomena or designs, such as climate and weather, evolution of the cosmos, nuclear weapons and reactors, new chemical compounds (especially for pharmaceutical purposes), and cryptology.
