Discover the diverse uses of supercomputers in scientific research, weather forecasting, aerospace, healthcare, and finance. Explore how these powerful machines drive innovation and advancements.In today’s digital age, supercomputers represent the pinnacle of computing power and performance. They enable tasks beyond the capabilities of conventional computers and play a key role in science, industry, and technology.
What is a supercomputer
A supercomputer is a computing system of exceptional power, capable of performing huge volumes of operations per second. The performance of such systems is measured in FLOPS (Floating Point Operations Per Second). Modern supercomputers reach figures in petaflops (PFLOPS) and even exaflops (EFLOPS). For comparison, the performance of a typical modern desktop computer or server is measured only in gigaflops (GFLOPS) or teraflops (TFLOPS).
Uses Of Supercomputers;Main areas of application of supercomputers.
Supercomputers are used in industries that require maximum computing power and work with big data.
Scientific research and modeling
Scientists use supercomputers for complex numerical calculations and simulations. For example, modeling processes in high-energy physics, studying new materials, calculations in astrophysics (events like the merger of black holes) require huge resources that only a supercomputer can provide. In the video, you can see a simulation of the origin of the universe using the Frontier supercomputer.
Weather and climate forecasting
Meteorologists and climate scientists use supercomputers to model the atmosphere and oceans. Calculating climate models for decades to come, predicting hurricanes and cataclysms—all of this requires processing colossal amounts of data in a short time.
Biology and medicine
In bioinformatics, supercomputers are used to decipher genomes, model protein structures, and search for new drugs. The process of sorting through millions of molecular combinations (in developing drugs or vaccines) is accelerated by parallel computing.
Artificial Intelligence and Big Data
Modern AI models (deep neural networks with billions of parameters) require huge resources for training. Supercomputers have become the basis for training such models – from speech and image recognition systems to large language models. Also, when analyzing Big Data, a supercomputer speeds up processing and finding patterns.
Industry and Engineering
Aircraft and car manufacturers, energy and oil and gas companies use supercomputers for engineering modeling and computational experiments. Aerodynamics of aircraft and cars, strength calculations of structures, simulation of nuclear reactors, search for mineral deposits – these tasks are solved faster and more accurately on super-powerful computing clusters.
State security
In the defense sector, supercomputers are used for cryptanalysis (breaking complex codes), simulating nuclear explosions, and other national security tasks that require exclusive computing power.
All of these areas benefit from the use of supercomputers: calculation times are reduced from months (or years) to hours and minutes, and previously unattainable research can be carried out.
The World’s Fastest Supercomputers
The era of exaflop supercomputers has arrived in early 2025. The leaders of the world Top500 ranking have surpassed the one exaflop performance mark (Linpack). Let’s take a quick look at some of the fastest supercomputers on the planet:
“El Capitan” (USA)
El Capitan is the world’s most powerful supercomputer as of February 2025. Its performance is about 1.74 exaflops (i.e. 1.74×10^18 operations/s). The system has more than 11 million cores: it uses a combination of 4th generation AMD EPYC server processors (24 cores per chip) and the latest AMD Instinct MI300A graphics accelerators, united by a high-speed Cray Slingshot-11 network.
El Capitan is installed at the Lawrence Livermore National Laboratory (USA). It will be used by the US Department of Energy to simulate nuclear processes (virtual nuclear tests, maintaining the reliability of the nuclear arsenal), as well as for advanced scientific research in the field of materials science, space, climate and AI development. Despite its colossal power, El Capitan is distinguished by high energy efficiency (~59 Gflops/W), entering the top green supercomputers (Green500).
“Frontier” (USA)
Frontier is the previous leader of the Top500 rating (2022–2023), the first officially registered exascale supercomputer. Its performance is about 1.35 exaflops (second place in the world). The architecture is based on the HPE Cray EX platform and combines the 3rd generation of AMD EPYC processors (64 cores, 2.0 GHz) with AMD Instinct MI250X graphics accelerators. The total number of cores exceeds 9 million; nodes are connected by the Slingshot-11 network.
Frontier operates at the Oak Ridge National Laboratory (ORNL, USA). It is involved in a wide range of research: computational physics, climate modeling, astrophysics, development of new materials. In addition, Frontier serves as a platform for the development of artificial intelligence technologies and big data analysis in projects of the US Department of Energy.
“Aurora” (USA)
Aurora is the third fastest supercomputer in the world as of early 2025. Its achievable performance is about 1.01 exaflops. Unlike El Capitan and Frontier, built on AMD, Aurora’s architecture is based on Intel technologies: the HPE Cray EX platform is used with a combination of high-performance Intel Xeon Max processors (52 cores per socket) and Intel Data Center GPU Max graphics accelerators. The total number of cores is more than 9.2 million, the nodes are connected by a Slingshot-11 interconnect.
Aurora is installed at the Argonne National Laboratory (ANL, Illinois, USA). It is designed for advanced research – from nuclear reactor modeling and new drugs to projects in climate science and artificial intelligence. Aurora is the first exascale system based on Intel processors and accelerators, expanding the diversity of technologies.
“Fugaku” (Japan)
Fugaku is a Japanese supercomputer that held the world’s top spot from 2020 to 2022. It is currently (2025) in the top ten, with a performance of about 442 petaflops. Fugaku was built by Fujitsu on ARM A64FX processors (48 cores, 2.2 GHz) without the use of GPU accelerators. The system has about 7.6 million cores, united by a high-speed TofuD network.
Fugaku is installed at the RIKEN research center (Kobe, Japan). It is used for a wide range of tasks: fundamental science (materials science, chemistry, astrophysics), modeling the spread of infections (including COVID-19 research), weather forecasting, AI development, and even drug discovery.
Chinese supercomputers
China also has powerful supercomputers (e.g. Sunway TaihuLight, Tianhe-2A), but in recent years new Chinese systems have not been represented in the open Top500 rating, so their exact performance is unknown. The leader in Europe is the HPC6 system in Italy (~478 petaflops), which demonstrates the global competition in this area.
Supercomputers remain a critical tool for science and technology. As of early 2025, world leaders are already operating exaflops capacities, which opens up new horizons for research. Russia, although inferior to the leaders in absolute performance, is developing its own high-performance systems and implementing them in business (Yandex, Sber) and science (Moscow State University and others). Further growth in capacity and expansion of the scope of application of supercomputers is expected – from fundamental research to everyday services based on AI.
