Linux dominates supercomputing

In addition to all its different successes, Linux dominates supercomputing: All 500 of the worlds quickest supercomputers run Linux, and that has been the case since November 2017, in line with the TOP500 group, which has been rating the 500 strongest laptop techniques since 1993. (A graph of Linux’ ascension is on the market on here.)

How did this occur?

A little bit historical past

Linux started life in 1991 as the private venture of 21-year-old Finnish scholar Linus Torvalds. I first grew to become conscious of it a number of years later whereas working at Johns Hopkins University’s physics and astronomy division the place I managed the division’s community and numerous servers with the assistance of a pair grad college students.

At the time, I used to be intrigued by Linux, however couldn’t think about how dominant the OS would develop into just because its supply code was obtainable to anybody who needed to work with it. I couldn’t forsee {that a} important group of huge firms would grasp its worth, work collectively and innovate to make Linux what it’s right this moment. Intense collaboration was key to this success, together with contributions from numerous people and organizations that features IBM, Intel, NVIDIA, Red Hat, Samsung, SUSE and lots of others. (Browsing the corporate members of the Linux Foundation is prone to make your jaw drop.)

The success of Linux may also be attributed to the truth that it’s open supply, non-proprietary, and extendable.

The TOP500

Twice a 12 months, in June and November, TOP500 releases it a listing of the 500 strongest laptop techniques ranked by their efficiency on one thing known as the LINPACK Benchmark, which requires the pc being examined to resolve a dense system of linear equations.

I’ve heard it mentioned, although not been capable of confirm, that Linux runs on greater than 90% of public clouds, greater than 60% of embedded techniques and IoT units, as a lot as 99% of supercomputers and greater than 80% of smartphones. If these claims are even near the reality, it attests to the success and flexibility of Linux

In the most recent TOP500 ranking, a Japanese supercomputer identify Fugaku (derived from an alternate identify for Mount Fuji) has taken the prime spot and pushed the previous leaders down a rank. Fugaku was co-developed by Riken and Fujitsu and makes use of Fujitsu’s 48-core A64FX ARM chip. This is the primary time a pc primarily based on ARM processors has topped the listing.

The laptop was totally assembled solely in May however has already helped struggle COVID-19 by sorting by way of greater than 2,000 medicine which may successfully block the virus and located a dozen that present promise.

Containerization, AI and ML

Recently I had an opportunity to debate Linux with Stefanie Chiras, vice chairman and common supervisor of the Red Hat Enterprise Linux enterprise unit. She sees Linux as tightly linked to supercomputing as a result of it gives the size and adaptability to help high-performance computing and exascale computing techniques – these which can be able to calculating a minimum of 1,018 floating level operations per second (1 exaFLOPS). She additionally sees Linux as including to the continued growth of synthetic intelligence and machine studying.

Chiras expects that containerization will allow increasingly researchers and analysts to learn from supercomputing energy. And, as somebody who has supplied help to each scientists and analysts over the previous few many years, I can admire what a distinction this may make of their work.

In discussing supercomputers, Chiras identified that, past having a Linux working system, the highest three quickest – Fugaku, Summit and Sierra – are all constructed from business {hardware}. Summit and Sierra are Power Systems-based, whereas Fugaku is the primary Arm-powered supercomputer to prime the listing. The days of purpose-built, customized {hardware} and software program in supercomputing might be over though new and demanding workloads like AI and sophisticated modeling require better and better energy.

(Chiras additionally wasn’t shy about mentioning that Red Hat Enterprise Linux is operating on 4 of the highest 10 supercomputers: the highest three plus quantity 9, Marconi-100.)

The character of open supply and the willingness of many firms to acknowledge its worth and work collectively to develop it have made Linux the highest OS for each supercomputers and micro-devices. We can anticipate continued enhancements in how the OS is deployed – together with getting supercomputing into the fingers of much more scientists and engineers – as we transfer ahead. As an individual who has spent near 40 years working with Unix and Linux techniques, I couldn’t be extra happy.
