Supercomputer

Introduction

A supercomputer is a type of computer with a high level of performance as compared to a general-purpose computer. The performance of a supercomputer is commonly measured in floating-point operations per second (FLOPS) instead of million instructions per second (MIPS).Since 2017, supercomputers have existed which can perform over 10¹⁷ FLOPS (a hundred quadrillion FLOPS, 100 petaFLOPS or 100 PFLOPS). For comparison, a desktop computer has performance in the range of hundreds of gigaFLOPS (10¹¹) to tens of teraFLOPS (10¹³). Since November 2017, all of the world's fastest 500 supercomputers run on Linux-based operating systems. Additional research is being conducted in the United States, the European Union, Taiwan, Japan, and China to build faster, more powerful and technologically superior exascale supercomputers.^[1]

Supercomputers were introduced in the 1960s, and for several decades the fastest was made by Seymour Cray at Control Data Corporation (CDC), Cray Research and subsequent companies bearing his name or monogram.^[2]

In 1960, UNIVAC built the Livermore Atomic Research Computer (LARC), today considered among the first supercomputers, for the US Navy Research and Development Center. It still used high-speed drum memory, rather than the newly emerging disk drive technology.

Supercomputers play an important role in the field of computational science, and are used for a wide range of computationally intensive tasks in various fields, including quantum mechanics, weather forecasting, climate research, oil and gas exploration, molecular modeling (computing the structures and properties of chemical compounds, biological macromolecules, polymers, and crystals), and physical simulations (such as simulations of the early moments of the universe, airplane and spacecraft aerodynamics, the detonation of nuclear weapons, and nuclear fusion). They have been essential in the field of cryptanalysis.^[3]

Special Purpose of supercomputer

Scientific Research and Simulation: Supercomputers are used for climate modeling, weather forecasting, and geophysics. They simulate natural phenomena like hurricanes, earthquakes, and long-term climate changes.

Drug Discovery and Healthcare: In biomedical research, supercomputers model molecular interactions to accelerate drug discovery and development, as well as analyze genome sequencing data.

Space Exploration: NASA uses supercomputers to simulate rocket launches, space travel, and planetary environments, helping in mission planning and trajectory calculations.^[4]

National Security and Cryptography: Supercomputers are crucial for encryption, decryption, and simulating nuclear explosions for defense purposes.

Artificial Intelligence and Machine Learning: Supercomputers train complex AI models and process massive amounts of data for machine learning applications.

Financial Modeling: They are used in finance to simulate market scenarios, perform risk assessments, and help institutions manage financial risks.

Evolution of Supercomputers

Supercomputers have seen significant advancements since their inception in the 1960s. Early systems, like the CDC 6600 developed by Seymour Cray in 1964, marked the beginning of the supercomputing era. This machine, capable of 3 million floating-point operations per second (FLOPS), was the fastest of its time. These early supercomputers relied on vector processing, where a single operation would process multiple data points simultaneously, making them ideal for scientific research and nuclear simulations. Over the next few decades, supercomputers transitioned from using vacuum tubes to transistors and integrated circuits, allowing for greater speed, reliability, and efficiency. The Cray-1, released in 1976, further popularized vector processing and became a key player in high-performance computing.

In the modern era, supercomputers have reached extraordinary speeds, capable of performing petascale (quadrillions of calculations per second) and even approaching exascale (quintillions of calculations per second) computing. Leading examples of current supercomputers include Fugaku^[5] in Japan, which is capable of over 442 petaflops, making it the fastest supercomputer in the world as of 2024. The Summit supercomputer, located at the Oak Ridge National Laboratory in the U.S., is another modern marvel, achieving 200 petaflops and used for critical applications in artificial intelligence, genomics, and climate research. China's Sunway TaihuLight and the LUMI^[6] supercomputer in Finland are other key players in the supercomputing space. These modern machines are pushing the boundaries of science and technology, enabling breakthroughs in fields such as drug discovery, weather prediction, and space exploration.
