Supercomputers History

 The Early Days of Supercomputing

• In the 1950s, various tech companies competed to build the fastest computers.
• IBM was a leader in this space with its IBM 7030 Stretch.
• In 1957, Control Data Corporation (CDC) was formed in Minneapolis, Minnesota, and one of its notable engineers was Seymour Cray.
• In 1964, Cray’s team at CDC completed the CDC 6600, which became the world’s fastest computer, three times faster than IBM’s offering.
• The CDC 6600 was so fast that it was dubbed a supercomputer. It had 400,000 transistors, over 100 miles of wiring, and could perform calculations at speeds up to 3 megaFLOPS, which was groundbreaking for its time.

The Cray Revolution

• Seymour Cray’s computer designs at CDC were impressive but expensive. Frustrated with corporate oversight, Cray left CDC to establish Cray Research.
• Cray Research dominated the supercomputer market during the 1970s and 1980s with machines like the Cray-1, Cray X-MP, and Cray-2, each offering significant performance improvements.
• Cray’s computers were known for their innovative designs and were instrumental in pushing the boundaries of supercomputing.
• While Cray’s vector-based supercomputers were influential, other tech companies began exploring massively parallel processing (MPP) to make supercomputers more affordable. MPP involved using thousands of processors working in conjunction with a single memory unit.
• Cray resisted this idea, and Cray Research ultimately went bankrupt in 1995.

New Age of Supercomputing

• In 1992, Don Becker and Thomas Sterling built the Beowulf supercomputer using off-the-shelf computer parts. Beowulf introduced the cluster model, which a supercomputer is made from a cluster of computer units working together.
• In 1997, Intel used the cluster model to develop the first 1 teraflop supercomputer, the ASCI Red.
• Modern supercomputers often use the cluster model and are designed to be more compact.

Supercomputing Today

• Modern supercomputers utilize both CPUs and GPUs working in tandem to perform calculations.
• Some high-performance GPUs found in gaming computers, like those from NVIDIA in HP OMEN machines, can perform supercomputer-caliber calculations.
• In 2019, IBM completed the fastest supercomputer in the world, the Summit, which could perform calculations as fast as 200 petaFLOPS. Some specific calculations could reach speeds of 3.3 exaFLOPS.
• Also in 2019, Cray was acquired by Hewlett Packard Enterprise, and they have been working on building supercomputers that can routinely achieve exascale speeds.
