A
group of computer engineers, including the six year old son of the project lead, built a supercomputer using 64
Raspberry Pi credit card sized mini computers and SD cards and putting them in racks made with Lego.
Each Raspberry Pi has 256Mb of RAM, a processor roughly equal to a 300MHz Pentium 2, and a high quality graphics processing unit "roughly equivalent to Xbox 1 level of performance." Long term memory is, of course, determined by the flash cards used (here 16 GB each). The overall cost was about $4000 excluding the switches for networking (this was at the
University of Southhampton in Hampshire, England, UK; the actual cost less switches was estimated to be less than £2500 ). Via
