“Cray systems” in popular culture
Cray supercomputers have shown up in popular culture, sometimes mentioning a specific machine type other times just using “Cray Computer” in a generic sense. Listed here are some references to Cray systems in popular culture. Let us know if you know more. Books Jurassic park – Mentioned in the Michael Critchton book but a Connection …
Cray-2s at the NSA
Correspondent Kevin Smith reports from FB Hi Clive, I went down in the basement and dug around in my “CRI museum” and pulled out a few things. So, SN2004 and SN2005 were covered under SS-12 and SS-18 for our customer. SN2004 was RED/WHITE/BLUE while SN2005 was a shade of Brown ( see pics). Do not …

Customer System books
From about 1987 to 1997, it was traditional that Cray Research would ship a customer system book showing images from the factory of how the system was built. Included in the book, were pictures of the staff and machines that built the customers machine. A couple of examples of the system book have been captured …
Cray-2 Diagnostic and indicator lights
If you look closely into the top of a Cray-2 we are able to make out rows of indicator lights that were used by service engineers to assess the state of a machine. In the event that a machine hung or unexpectedly halted, the indicator lights were examined to gain some idea of what was …

vi on a Cray supercomputer
Ever wondered what the text editor vi looked like on a Cray supercomputer? As a core part of the UNIX operating system, used by programmers and system administrators for editing and adjusting text files, the vi editor looked worked and behaves much as it does everywhere else. Under the covers, however, some clever programming was …
