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

Cray X1 Cpu module Teardown
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.

Sonja’s Story about Cray-1 fabrication and assembly
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

ORNL Run Frontier at an Exascale with 52 GFlops a watt.
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
