Humanity has not yet reached Mars, a cure for all diseases has not yet been invented, cars do not fly, but nevertheless, there are areas in which people have reached unprecedented heights. The computing power of computers is one of them.
First, let's figure out what the key parameter is when assessing this characteristic of supercomputers. Flops is a value showing the number of floating-point operations that a computer can perform per second. Based on this indicator, our rating of the most powerful computers in the world was compiled, according to 2019 data.
The ranking was presented at the International Supercomputing Conference, and the top 500 supercomputers were compiled by mathematicians from the Lawrence Livermore National Laboratory and the University of Tennessee.
10. Trinity
This supercomputer guards the US military security, maintaining the effectiveness of the national nuclear arsenal. Given this, you might think that this machine is incredibly expensive, but since 2015, new, more powerful supercomputers have begun to displace it. Trinity is based on the Cray XC40 system, its performance is 8.1 petaflops/sec.
9. Mira
Mira is another brilliant product of the Cray company. It is worth noting that the project of this supercomputer was developed by order of the United States Department of Energy. The main area of application of Mira is government industrial and scientific research projects. The computing power of this computer is 8.6 petaflops per second.
8. K Computer
The peculiarity of this supercomputer is hidden in its name, which comes from the Japanese word "kei" and means 10 quadrillion. The productive capacity of the K Computer is approximately limited to this figure - 10.5 petaflops. The specificity of this technology is also that the system uses water cooling, which allows to significantly reduce energy consumption and reduce the speed of assembly.
7. Oakforest-Pacs
The Japanese company Fujitsu, which also developed the K Computer mentioned earlier, has created a new generation supercomputer (Knights Landing generation). The project was completed by order of the Tokyo and Tsukuba universities. Despite the fact that it was initially planned to equip the computer with 900 TB of memory and a performance of 25 quadrillion operations, its computing power is 13.6 petaflops/s.
6. Cory
Until 2017, Cori held a solid 5th position in the world ranking of the most powerful computers, but in the context of rapidly developing technical progress, it still lost one rating “line” to the latest supercomputers. It is located at the Lawrence Berkeley National Laboratory in the USA. Cori has already made its unique contribution to the development of science: with its help, Swiss scientists were able to simulate a 45-qubit quantum computing system. 14 petaflops is the productive capacity of this “supermachine”.
5. Sequoia
Many experts call Sequoia the fastest supercomputer in the world, and for good reason: its arithmetic performance is equal to the speed of 6.7 billion people who would perform an identical task using calculators for 320 years. Sequoia is also distinguished by its size: the computer occupies an area of 390 square meters and consists of 96 racks. 17.2 petaflops is its performance, which is equal to almost sixteen thousand trillion operations.
4. Titan
In addition to being one of the fastest computers in the world, Titan is also considered one of the most energy efficient, with a rating of 2142.77 megaflops per watt of consumed energy. The secret to saving energy is the use of Nvidia accelerators, providing up to 90% of total computing power, which, by the way, is 17.6 petaflops. Thanks to them, Titan has significantly reduced its dimensions - now it only needs 404 square meters to be placed.
3. Piz Daint
The Piz Daint supercomputer project was launched back in 2013, in the Swiss city of Lugano. It is located there, in the Swiss National Supercomputer Center. Piz Daint has almost all the positive characteristics of the above-mentioned analogs, including energy efficiency and high speed, except for its compactness: the device consists of 28 large-sized racks. Its computing power is 19.6 petaflops.
2. Tianhe-2
The supercomputer with the romantic name "Milky Way" (translated from Chinese) headed the top 500 most powerful computers in the world until June 2016. Its power provides a speed of 2507 trillion operations per second, which is equal to 33.9 petaflops. Tianhe-2 found its "vocation" in the field of construction: in calculating buildings and road construction. It is worth noting that since the beginning of 2013, as soon as the "Milky Way" was released, it has not left the leading position in the ratings, which is a truly powerful indicator.
1. Sunway Taihu Light
Inside this computer there are 40,960 productive processors, which explains its dimensions: Sunway itself occupies an area of about 1,000 square meters. In 2016, at an international conference in Germany, it was recognized as the fastest of its kind. Today, Sunway TaihuLight is the first in the ranking and the only one in the top 10 supercomputers capable of generating a speed of 93 petaflops.
