Many of us are familiar with computers. You’re likely using one now to read this blog post as devices such as laptops, smartphones and tablets are essentially the same underlying computing technology. Supercomputers, on the other hand, are somewhat esoteric as they’re often thought of as hulking, costly, energy-sucking machines developed, by and large, for government institutions, research centers and large firms.
Take for instance China’s Sunway TaihuLight, currently the world’s fastest super computer, according to Top500’s supercomputer rankings. It’s comprised of 41,000 chips (the processors alone weigh over 150 tons), cost about $270 million and has a power rating of 15,371 kW. On the plus side, however, it’s capable of performing quadrillions of calculations per second and can store up to 100 million books. And like other supercomputers, it’ll be used to tackle some of the most complex tasks in the fields of science such as weather forecasting and drug research.
The notion of a supercomputer first arose in the 1960’s when an electrical engineer named Seymour Cray, embarked on creating the world’s fastest computer. Cray, considered the “father of supercomputing,” had left his post at business computing giant Sperry-Rand to join the newly formed Control Data Corporation so that he can focus on developing scientific computers.
The title of world’s fastest computer was held at the time by the IBM 7030 “Stretch,” one of the first to use transistors instead of vacuum tubes.
In 1964, Cray introduced the CDC 6600, which featured innovations such as switching out germanium transistors in favor of silicon and a Freon-based cooling system.
More importantly, it ran at a speed of 40 MHz, executing roughly three million floating-point operations per second, which made it the fastest computer in the world. Often considered to be the world’s first supercomputer, the CDC 6600 was 10 times faster than most computers and three times faster than the IBM 7030 Stretch. The title was eventually relinquished in 1969 to its successor the CDC 7600.
In 1972, Cray left Control Data Corporation to form his own company, Cray Research. After some time raising seed capital and financing from investors, Cray debuted the Cray 1, which again raised the bar for computer performance by a wide margin. The new system ran at a clock speed of 80 MHz and performed 136 million floating-point operations per second (136 megaflops). Other unique features include a newer type of processor (vector processing) and a speed-optimized horseshoe-shaped design that minimized the length of the circuits. The Cray 1 was installed at Los Alamos National Laboratory in 1976.
By the 1980’s Cray had established himself as the preeminent name in supercomputing and any new release was widely expected to topple his previous efforts. So while Cray was busy working on a successor to the Cray 1, a separate team at the company put out the Cray X-MP, a model that was billed as a more “cleaned up” version of the Cray 1.
It shared the same horseshoe-shape design, but boasted multiple processors, shared memory and is sometimes described as two Cray 1s linked together as one. In fact, the Cray X-MP (800 megaflops) was one of the first “multiprocessor” designs and helped open the door to parallel processing, wherein computing tasks are split into parts and executed simultaneously by different processors.
The Cray X-MP, which was continually updated, served as the standard bearer until the long anticipated launch of the Cray 2 in 1985. Like its predecessors, Cray’s latest and greatest took on the same horseshoe-shaped design and basic layout with integrated circuits stacked together on logic boards. This time, however, the components were crammed so tightly that the computer had to be immersed in a liquid cooling system to dissipate the heat.
