The Atanasoff–Berry computer (ABC) was the first automatic electronic digital computer. Limited by the technology of the day, and execution, the device has remained somewhat obscure. The ABC's priority is debated among historians of computer technology, because it was neither programmable, nor Turing-complete. Conventionally, the ABC would be considered the first electronic ALU – which is integrated into every modern processor's design.

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.
John Vincent Atanasoff was an American physicist and inventor credited with inventing the first electronic digital computer. Atanasoff invented the first electronic digital computer in the 1930s at Iowa State College. Challenges to his claim were resolved in 1973 when the Honeywell v. Sperry Rand lawsuit ruled that Atanasoff was the inventor of the computer. His special-purpose machine has come to be called the Atanasoff–Berry Computer.
Cray Inc., a subsidiary of Hewlett Packard Enterprise, is an American supercomputer manufacturer headquartered in Seattle, Washington. It also manufactures systems for data storage and analytics. Several Cray supercomputer systems are listed in the TOP500, which ranks the most powerful supercomputers in the world.
A graphics processing unit (GPU) is a specialized electronic circuit initially designed to accelerate computer graphics and image processing. After their initial design, GPUs were found to be useful for non-graphic calculations involving embarrassingly parallel problems due to their parallel structure. Other non-graphical uses include the training of neural networks and cryptocurrency mining.
High-performance computing (HPC) uses supercomputers and computer clusters to solve advanced computation problems.

Previously, he served as the Chair of the Georgia Institute of Technology School of Computational Science & Engineering, where he was also a founding professor, and the executive director of High-Performance Computing at the Georgia Tech College of Computing. In 2007, he was named the first director of the Sony Toshiba IBM Center of Competence for the Cell Processor at Georgia Tech.
ClearSpeed Technology Ltd was a semiconductor company, formed in 2002 to develop enhanced SIMD processors for use in high-performance computing and embedded systems. Based in Bristol, UK, the company has been selling its processors since 2005. Its current 192-core CSX700 processor was released in 2008, but a lack of sales has forced the company to downsize and it has since delisted from the London stock exchange.
Mitrionics was a Swedish company manufacturing softcore reconfigurable processors. It has been mentioned as one of EETimes "60 Emerging startups". The company was founded as Flow Computing in 2002 by Stefan Möhl, Pontus Borg, Andreas Rodman and Christian Merheim to commercialize a massively parallel reconfigurable processor implemented on FPGAs. Mitrion-C was then invented and developed by Stefan Möhl and Pontus Borg. It can be described as turning general purpose chips into massive parallel processors that can be used for high performance computing. Mitrionics massively parallel processor is available on Cray, Nallatech, and Silicon Graphics systems.
The Ken Kennedy Award, established in 2009 by the Association for Computing Machinery and the IEEE Computer Society in memory of Ken Kennedy, is awarded annually and recognizes substantial contributions to programmability and productivity in computing and substantial community service or mentoring contributions. The award includes a $5,000 honorarium and the award recipient will be announced at the ACM - IEEE Supercomputing Conference.

Unums are a family of number formats and arithmetic for implementing real numbers on a computer, proposed by John L. Gustafson in 2015. They are designed as an alternative to the ubiquitous IEEE 754 floating-point standard. The latest version is known as posits.
Floating-point error mitigation is the minimization of errors caused by the fact that real numbers cannot, in general, be accurately represented in a fixed space. By definition, floating-point error cannot be eliminated, and, at best, can only be managed.
Cerebras Systems Inc. is an American artificial intelligence company with offices in Sunnyvale and San Diego, Toronto, Tokyo and Bangalore, India. Cerebras builds computer systems for complex artificial intelligence deep learning applications.
JUWELS is a supercomputer developed by Atos and hosted by the Jülich Supercomputing Centre (JSC) of the Forschungszentrum Jülich. It is capable of a theoretical peak of 70.980 petaflops and it serves as the replacement of the now out-of-operation JUQUEEN supercomputer. JUWELS Booster Module was ranked as the seventh fastest supercomputer in the world at its debut on the November 2020 TOP500 list. The JUWELS Booster Module is part of a modular system architecture and a second Xeon based JUWELS Cluster Module ranked separately as the 44th fastest supercomputer in the world on the November 2020 TOP500 list.
