It’s not often that the worlds of fashion and glamour intersect with the hard industrial process of creating a supercomputer. We are used to seeing how supercomputers have changed the world of engineering and technology but discovering this story during research into the 250 issues of Cray Chips was an unexpected angle. From this issue

Toby Harness reports – I released detailed YMP and Cray-2 3D model plans on Thingiverse.com The YMP can run a full emulator, booting UNICOS (by Modular Circuits/The Cray Files). The Cray 2 doesn’t have an emulator, but does have a floodable tank option, with an air or water pump for bubbles (this option is still

Seymour Cray was a serial inventor at a large and small scale. Having a look at a couple of his patents can be quite enlightening. Browsing over at the US patent office the earliest found was “US-2741758-A Magnetic core logical circuits. From April 1956“. This patent was to reduce the power consumption and improve reliability

Cray Stories During the 25 years that I worked for Cray I was fortunate enough to meet many interesting people and hear many stories and urban legends about Seymour Cray, the company as well as interesting events that happened in the field. In some cases I even got to hear the story behind the story.
