The University of Southampton (UK) has put out a press release
about a 64-node supercomputer recently built out of Raspberry Pi systems. In addition, the racks were built out of Lego. "Professor [Simon] Cox adds: 'The first test we ran – well obviously we calculated Pi on the Raspberry Pi using MPI, which is a well-known first test for any new supercomputer.'
'The team wants to see this low-cost system as a starting point to inspire and enable students to apply high-performance computing and data handling to tackle complex engineering and scientific challenges as part of our on-going outreach activities.'
" There is a guide
to building your own, as well as a page for pictures of the supercomputer
