Cray-1 - The home supercomputer

Giovedì 01 Dicembre 2016, 20:50

Cray-1AIt took me almost a year to complete the Cray-1 project during my spare time. When I decided to build a physical copy of the first supercomputer ever, as faithful as possible, I found on the web a lot of inspiring examples (just like this one by Chris Fenton). In 1975 the 80 MHz Cray-1A was announced. Excitement was so high that a bidding war for the first machine broke out between Lawrence Livermore National Laboratory and Los Alamos National Laboratory, the latter eventually winning and receiving serial number 001 in 1976 for a six-month trial. Since then, the Cray-1 supercomputer reigned as the world’s fastest from 1976 to 1982 (source).

My personal 1:8 Cray-1A was made laser cutting some plexiglass sheets after a careful drafting process of the main vertical framework, which originally hosted over 60 miles of wire with no segment longer than 3 inches, to minimize signal delays. Amazing! My Cray-1A is equipped with a Rasperry Pi 2 board (out of 12 possible parallel slots) running a customized Os: a dedicated I2C controller drives a 16x2 characters LCD blue display while wi-fi and bluetooth interfaces guarantee wireless connections.
