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.

Dal 2004 questo piccolo angolo di rete raccoglie gli interessi di ricerca e i lavori di sperimentazione digitale di Simone Garagnani in materia di cultura geek, ma soprattutto di Building Information Modeling, rilievi digitali ad alta risoluzione e computer graphics legata al mondo dell'architettura, dell'ingegneria e delle costruzioni. TC Project, è presente anche sul social network Facebook.


Welcome to these pages that host since 2004 Simone Garagnani's personal blog, a collection of nerd notes and geek experiences focused sometimes on Building Information Modeling, terrestrial laser scanning, digital photogrammetry and computer graphics applied to the AEC world. The TC Project is also available on Facebook.
