Gadgets and apps to help you get (and stay) fit and healthy in 2019
Let's start 2019 as we mean to go on -- by sitting less and moving more!
Six-year-old James Cox has helped his dad and other engineers at the University of Southampton to build a £2,500 supercomputer-style cluster out of 64 Linux-based Raspberry Pi PCs and Lego.
A team of computational engineers at the University of Southampton has built a working supercomputer-like cluster out of 64 Raspberry Pi boards.
The cluster sits on racks made of Lego, runs off a standard mains socket, and has a total memory of 1TB, derived from 16GB SD cards on each Raspberry Pi. Its total cost was £2,500.
"As soon as we were able to source sufficient Raspberry Pi computers, we wanted to see if it was possible to link them together into a supercomputer," said Professor Simon Cox, who led the project and even enlisted the help of his six-year-old son James in the design.
The computer uses a system called MPI (Message Passing Interface) to communicate between nodes using Ethernet. According to Professor Cox, the machine's first task was to calculate Pi on the Raspberry Pi using MPI.
