New guide: Bake your own Raspberry Pi Lego-crust cluster 'And
here's one we made earlier!' Pics Scientists at the University
of Southampton have built a "supercomputer" from Raspberry Pis
lashed together to form a colourful data-cruncher. Professor
Simon Cox and his team racked up 64 credit card-sized Pis using
Lego building blocks to create the parallel computer. They named
their beast Iridis-Pi after the university's Intel-powered
72-teraflops supercomputer, Iridis. Here's a photo of their very
modest super in all its Pi-and-brick glory: Back of the net:
Ethernet cables running to Iridis-Pi's nodes The cheapo cluster
has 1TB of storage, thanks to the 16GB SD card inserted into
each board, and 16GB of RAM. Each Pi is connected by 100MBit
Ethernet, and is powered by a Broadcom BCM2835 graphics chip
that handily features a 700MHz ARMv6 processor core. A two-Pi
