From ENIAC to Exascale: A Timeline of Supercomputing Achievements

Supercomputers have revolutionized the way we process and analyze data, enabling us to solve complex problems and make groundbreaking discoveries. From the first electronic computer to the latest exascale machines, the evolution of supercomputing has been a remarkable journey. In this article, we will take a look at the major milestones in the history of supercomputing and how it has shaped our world today.

The Birth of ENIAC

The first electronic computer, ENIAC (Electronic Numerical Integrator and Computer), was developed in 1946 by John Mauchly and J. Presper Eckert at the University of Pennsylvania. It was a massive machine, weighing 30 tons and occupying a space of 1,800 square feet. ENIAC was primarily used for military calculations, such as creating ballistic tables for the US Army during World War II.

ENIAC was a significant breakthrough in computing technology, as it was the first general-purpose electronic computer. It could perform calculations 1,000 times faster than any previous machine, making it the world’s fastest computer at that time. However, it had limited memory and required manual programming, which made it challenging to use for complex tasks.

The Rise of Supercomputers

In the 1960s, supercomputers emerged as a new category of computers designed for high-speed processing and complex calculations. The first supercomputer, Control Data Corporation’s CDC 6600, was introduced in 1964. It was the world’s fastest computer for the next four years, with a processing speed of 3 million instructions per second (MIPS).

Supercomputers continued to evolve in the following decades, with companies like Cray Research and IBM leading the way. In 1976, Cray-1 became the first supercomputer to use vector processing, which allowed it to perform calculations on large arrays of data simultaneously. It was also the first supercomputer to break the 1 gigaflop (billion floating-point operations per second) barrier.

In the 1980s, the Japanese government launched the Fifth Generation Computer Systems project, aiming to develop a supercomputer that could perform parallel processing. This led to the development of the first massively parallel processing (MPP) supercomputer, the Fujitsu VP200, in 1983. MPP supercomputers use multiple processors to work on different parts of a problem simultaneously, significantly increasing their processing power.

The Era of Cluster Computing

In the 1990s, cluster computing emerged as a new approach to supercomputing. Instead of using a single powerful processor, cluster computing connects multiple computers to work together as a single system. This approach was more cost-effective and scalable, making it popular among research institutions and universities.

In 1993, the first Beowulf cluster, a type of cluster computing, was built by NASA. It was made up of 16 Intel 486 processors and was used for scientific simulations and data analysis. Beowulf clusters became increasingly popular in the 2000s, with the development of open-source software and hardware, making it easier and more affordable to build supercomputers using commodity components.

The Exascale Era

In 2008, the term “exascale” was coined to describe a computer that could perform a billion billion calculations per second (1 exaflop). This was considered the next milestone in supercomputing, and several countries and companies began working towards achieving it.

In 2018, the US Department of Energy announced its plan to build the first exascale supercomputer, named Aurora, by 2021. It will be capable of performing 1 exaflop and will be used for scientific research, including climate modeling, energy research, and astrophysics. China, Japan, and the European Union are also working on their exascale supercomputers, with the goal of achieving it by 2022.

The Impact of Supercomputing

Supercomputers have played a crucial role in various fields, including weather forecasting, climate modeling, drug discovery, and space exploration. They have also been used to solve complex problems in physics, chemistry, and biology, leading to groundbreaking discoveries and advancements in these fields.

For example, in 2016, the world’s fastest supercomputer, Sunway TaihuLight, was used to simulate the behavior of a protein molecule, leading to a better understanding of how it functions and potential treatments for diseases. In 2019, the Summit supercomputer was used to analyze genetic data from over 250,000 individuals, leading to the discovery of new genetic variants associated with diseases like diabetes and heart disease.


The evolution of supercomputing has been a remarkable journey, from the massive ENIAC to the latest exascale machines. Supercomputers have enabled us to solve complex problems and make groundbreaking discoveries, shaping our world today. With the continuous advancements in technology, we can only imagine what the future holds for supercomputing and the impact it will have on our lives.
