An endless variety of apps and experiences with computing power that matches today\u2019s desktops. But consider the power of a real supercomputer, and suddenly that smartphone pales in comparison. You can find supercomputers solving some serious problems in the fields of:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span style=\"font-weight: 400;\">Quantum mechanics<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Weather forecasting<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Molecular modeling<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Oil and gas exploration<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Physical simulations<\/span><\/li>\n<\/ul>\n\n\n\n<p><span style=\"font-weight: 400;\">Whether its for automobiles, energy, or explaining the origins of our universe, supercomputers seem to be able to do it all. Unlike our smartphones and computers, supercomputers are made from tens of thousands of CPUs, with thousands of gigabytes of RAM. All of this speed isn\u2019t measured in your typical gigahertz. A supercomputer is measured by how many floating-point operations per second it can perform, called flops.<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"397\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/600px-IBM_Blue_Gene_P_supercomputer.jpg\" alt=\"\" class=\"wp-image-57800\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/600px-IBM_Blue_Gene_P_supercomputer.jpg 600w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/600px-IBM_Blue_Gene_P_supercomputer-300x199.jpg 300w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/600px-IBM_Blue_Gene_P_supercomputer-366x241.jpg 366w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p><i><span style=\"font-weight: 400;\">(<\/span><\/i><a href=\"https:\/\/en.wikipedia.org\/wiki\/Supercomputer\"><i><span style=\"font-weight: 400;\">Image source<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">)<\/span><\/i><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">The continued advancement of supercomputers can be accredited to one man that many consider The Father of Supercomputers, Seymour Cray. As Joel Birnbaum, former CTO at Hewlett-Packcard puts it:<\/span><\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><i><span style=\"font-weight: 400;\">\u201cIt seems impossible to exaggerate the effect he had on the industry; many of the things that high performance computers now do routinely were at the furthest edge of credibility when Seymour envisioned them. Seymour combined modesty, dedication and brilliance with vision and an entrepreneurial spirit in a way that places him high in the pantheon of great inventors in any field. He ranks up there with Edison and Bell of creating an industry.\u201d<\/span><\/i><\/p>\n<\/blockquote>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"525\" height=\"383\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/ows_142213380536625.jpg\" alt=\"seymour cray\" class=\"wp-image-57805\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/ows_142213380536625.jpg 525w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/ows_142213380536625-300x219.jpg 300w\" sizes=\"auto, (max-width: 525px) 100vw, 525px\" \/><\/figure>\n\n\n\n<p><i><span style=\"font-weight: 400;\">(<\/span><\/i><a href=\"http:\/\/www.startribune.com\/minnesota-history-seymour-cray-s-mind-worked-at-super-computer-speed\/289683511\/\"><i><span style=\"font-weight: 400;\">Image source<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">)<\/span><\/i><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"seymours-early-years\"><span style=\"font-weight: 400;\">Seymour\u2019s Early Years<\/span><\/h2>\n\n\n<p><span style=\"font-weight: 400;\">Seymour\u2019s story begins like many other famous electrical engineers. He had a fascination with electronics at an early age, and Cray says that he spent as much time as possible at his school\u2019s electrical engineering laboratory. After high school Cray used his natural talents in electrical engineering in the US Army as part of a communications platoon. <\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Seymour\u2019s first journey in supercomputing began at Engineering Research Associates (ERA). It was here that he began working with a variety of computer technologies, from vacuum tubes to transistors and magnetic amplifiers. <\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Cray\u2019s daughter, Susan Cray-Borman, remembers her father as an intensely focused and solitary man. She would often find him hovering over a piece of graph paper with a finely sharpened pencil, working away at some challenging engineering problem in a quiet space. Other colleagues described Seymour\u2019s brilliance at knowing when he had achieved that perfect balance of design simplicity and knew exactly where to stop. <\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">The video below gives a great perspective on Seymour\u2019s contributions and personality from both family and colleagues:<\/span><\/p>\n\n\n<?xml encoding=\"utf-8\" ?><figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-4-3 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Seymour Cray -- Father of the Supercomputing Industry\" width=\"500\" height=\"375\" src=\"https:\/\/www.youtube.com\/embed\/7PvfbbaiDdc?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen style=\"aspect-ratio:500 \/ 375;width:100%;height:auto;\"><\/iframe>\n<\/div><\/figure>\n\n\n\n<p><span style=\"font-weight: 400;\">Cray went through several management transitions and mergers during his time at ERA, and was vocal about his frustrations with corporate culture. He later teamed up with William C. Norris, founder of ERA, and the two left the company to found Control Data Corporation (CDC). <\/span><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"the-advancement-of-supercomputers\"><span style=\"font-weight: 400;\">The Advancement of Supercomputers<\/span><\/h2>\n\n\n<p><span style=\"font-weight: 400;\">In 1957 Cray and his team released the CDC 1604, the world\u2019s first fully transistorized supercomputer that worked without vacuum tubes. A few years later Cray followed up with the CDC 6600. This $7 million machine touted the world\u2019s fastest clock speed of 100 nanoseconds. It was also the first supercomputer to use Freon to keep its electronic components from overheating. CDC would later release another series of successful supercomputers, including the CDC 7600 in 1968 and CDC 8600 in 1970.<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"418\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/CDC_6600.jc_.jpg\" alt=\"supercomputer\" class=\"wp-image-57810\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/CDC_6600.jc_.jpg 600w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/CDC_6600.jc_-300x209.jpg 300w\" sizes=\"auto, (max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<p><i><span style=\"font-weight: 400;\">(<\/span><\/i><a href=\"https:\/\/en.wikipedia.org\/wiki\/CDC_6600\"><i><span style=\"font-weight: 400;\">Image source<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">)<\/span><\/i><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">At CDC Seymour continued to struggle with his business counterparts. When William Norris asked Cray for a five-year business plan for CDC, he responded with:<\/span><\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><i><span style=\"font-weight: 400;\">\u201cFive-year goal: Build the biggest computer in the world. One-year goal: Achieve one-fifth of the above.\u201d <\/span><\/i><\/p>\n<\/blockquote>\n\n\n\n<p><span style=\"font-weight: 400;\">The situation escalated to Seymour convincing Norris to relocate his laboratory over 100 miles away to Minneapolis. One can imagine the intense focus that Cray required to do his creative work conflicting with a busy office environment. <\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Cray decided to begin a new business venture in 1975, Cray Research. It was here that Seymour developed the Cray-1, which wasn\u2019t your ordinary supercomputer. This machine completely replaced transistors with integrated circuits, and also introduced a new technology called Vector Processing.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Vector Processing basically allowed Cray\u2019s supercomputer to execute an instruction set that operated on one-dimensional data arrays. This technology boosted system performance when compared with traditional scalar processing techniques used in other supercomputers. The use of integrated circuits also allowed Cray\u2019s machine to reach speeds of 136 megaflops. <\/span><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"455\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/vector-1.jpg\" alt=\"vector register\" class=\"wp-image-57815\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/vector-1.jpg 768w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/vector-1-300x178.jpg 300w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<p><i><span style=\"font-weight: 400;\">(<\/span><\/i><a href=\"http:\/\/www.ausairpower.net\/OSR-0600.html\"><i><span style=\"font-weight: 400;\">Image source<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">)<\/span><\/i><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">What\u2019s really remarkable about the Cray-1 isn\u2019t just its breakneck speeds, but its elegant design. <\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Look at most computers and you\u2019ll see a bland variation of black and white boxes.

This cushion didn\u2019t just house hardware, it also allowed a maintenance technician to be as comfortable as possible when servicing the machine. Seymour designed not only a supercomputer but an entire physical experience. When the Cray-1 was released in 1977 for $8.8 million, it earned the nickname of \u201cWorld\u2019s most expensive loveseat.\u201d<\/span><\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"319\" height=\"210\" src=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/1605807.jpg\" alt=\"cray 1\" class=\"wp-image-57830\" srcset=\"https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/1605807.jpg 319w, https:\/\/www.autodesk.com\/products\/fusion-360\/blog\/wp-content\/uploads\/2023\/07\/1605807-300x197.jpg 300w\" sizes=\"auto, (max-width: 319px) 100vw, 319px\" \/><\/figure>\n\n\n\n<p><i><span style=\"font-weight: 400;\">(<\/span><\/i><a href=\"http:\/\/www.chipsetc.com\/cray-research.html\"><i><span style=\"font-weight: 400;\">Image source<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">)<\/span><\/i><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">There were a variety of other fine touches that Cray introduced in nearly all of his supercomputers.

This might have been due to Seymour\u2019s experimentations with using gallium arsenide processing chips to replace silicon. After the failure of the Cray 3, Seymour formed Cray Computer Corporation (CCC) in 1989. It was here that he spent time behind closed doors working on the Cray 4, which never saw the light of day. <\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Sadly, on October 5th, 1996 Seymour passed away after struggling with injuries from a car accident. <\/span><\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"a-legendary-legacy\"><span style=\"font-weight: 400;\">A Legendary Legacy<\/span><\/h2>\n\n\n<p><span style=\"font-weight: 400;\">Seymour Cray was nothing short of an innovator in the world of supercomputers.
