A Cray-1 supercomputer replica from 30 “obsolete” Mac Minis
Summary
Ars Technica reports on a 1:1 scale Cray-1 replica built by Spain’s Museo de Historia de la Computación using 30 Mac Minis from around 2012. The cluster achieves about 1.3 teraflops with 64 active cores, and previously reached 1.5 teraflops with 70 cores before a node failed. The project showcases retro computing aesthetics, MPI-based inter-node communication, and near-silent cooling via passive convection.
