From https://cray-cyber.org/old/systems/E10kborn.php How the Sun Enterprise 10000 was born A group of engineers in San Diego left their jobs at well established corporations (especially a large number of former NCR employees) to form their own company. They set out to build massively parallel computers with Sparc processors. The market they were targetting has traditionally been

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.

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

This large tech museum in Padaborn Germany has SN2o18 Cray-2 on display. Editor note: SN2018 is currently listed as having previously worked at National Energy Research Supercomputer Center (NERSC) @ Lawrence Berkeley Livermore Labratory and Internal machine at Cray Research, Inc (CRI). Not sure how it ended up in Europe unless it did some time

Over here at Cray-history.net we pleased to see the release of this work by Cray Colleague David Barkai. It’s a great read and I certainly filled in a few gaps in my understanding of HPC history. David adds: “I have spent the last few years writing a book about HPC. It is now done and

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

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

The Cray X1 (also also known as the SV2 ) had a very innovative cooling method. A multichip module is mounted in a metal shell inside which four sprayheads delivere cooling liquid directly to the module face. Inside the sealed module the coolant to undergo a partial phase change extracting heat directly from the chips.
