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.

This interesting TV Program from 1987 The Computer Chronicles – Super Computers Episode Has information about NASA Ames Cray-2 and Los Alamos C1 & XMP. Shows the systems in there working environment along with explanations as to how the Cray systems are advancing science. About 30 Minutes – First part on NAS Ames Cray 2 then onto
The HASE Cray-1 Simulation Model is available here “Simulation models of a variety of computer architectures and architectural components have been created using HASE, a Hierarchical Computer Architecture design and Simulation Environment. These models are intended for use as teaching and learning resources: in lectures, for student self-learning or for virtual laboratory experiments. Using the models requires

After seeing these pictures that seem to have the wire-mat showing on the module side of the frame I asked Sonja about the Cray-1 construction process: Sonja’s Story A little history you might already know: Seymour Cray was working for Control Data. I believe he wanted to build ‘his’ computer but CDC was going in

From The Register article …. Frontier marks the first publicly benchmarked exascale computer by quite a margin. The ORNL system is well ahead of Fugaku’s 442 petaflops of performance, which was a strong enough showing to keep Fugaku in the top spot for two years. Reaching exascale status is one thing, but many expected

Fifty years of Cray supercomputers was celebrated with a virtual tour hosted by TNMOC in UK on 6th April 2022 This virtual talk explored the physical and logical structure of Cray-1 SN34, peaking ‘under the covers’ of this remarkable machine. The talk also illuminates how these machines evolved and sample some of what was achieved

The end of the ’90s was tough few years for supercomputers. These articles describe the spat that broke out between Cray and NEC a Japanese firms that was accused of selling supercomputers at less than cost price. After the spat was settled Cray entered an agreement to resell NEC supers SX-5 & SX-6 into the

The National Centre for Atmospheric Research NCAR/UCAR in Colorado has a long association with Cray supercomputers. Starting in 1977 with the Cray-1 SN3 the site invested in some the best supercomputers available. More recently a Cray Petaflop class machines will be used to explore climate research. In 2024 the site has commissioned Derecho a 19

This cautionary tale of how a USD10 million Cray machine was built but never delivered due to regulatory delay. Turns out it was not super-computers but more likely to be a rogue scientist that let the nuke secrets out the flask. From Wikipedia: “In 2004, the Pakistani metallurgist Abdul Qadeer Khan, a key figure in
