Spanish Museum Recreates Cray-1 at Full Scale With 30 Mac minis
Spain's computer museum recreates the Cray-1 at full scale, powered by 30 older Mac minis.
Based on an article by Nick Indge for Ars Technica.
The Museo de Historia de la Computación in Spain has unveiled a 1:1 scale visual replica of the famous Cray-1 supercomputer from 1976.
Instead of sourcing expensive, cutting-edge tech to run the system, the creative team powered the project with 30 2012-era Mac Minis.
Developed over 18 months, the project serves as a 50th-anniversary tribute to the Cray-1 and Apple’s founding.
Editorial Opinion
Over the next 3-6 months, we expect attention to focus on its drawing power as a working exhibit. The method of visualizing measured values is likely to spread to exhibit updates at other museums. Reusing older devices is likely to be referenced as a case study in curbing procurement costs.
Over 1-3 years, we assess that the museum’s role in balancing preservation with operation will strengthen. The contrast between vector processing and distributed parallelism looks set to become a staple of computing education. Efforts to save power and reduce noise will remain as knowledge for small-scale integration.
The remaining question is how to disclose the conditions for performance measurement. We see comparison as difficult based only on a custom matrix-multiplication procedure. We assess that disclosure of the measurement environment and reproduction steps is required.
