The humble Raspberry Pi has been around for some time and its popularity is growing again with the latest release of the Pi and is a great development platform for the Internet of Things both cost wise and its sheer versatility from basic programming and running Minecraft, to hosting a Docker server.

GCHQ have recently announced the clustering of a 66 node Pi cluster called bramble. They have just pipped the University of Southampton who built a 64 node Pi cluster out of the Pi and Lego.

Some other earlier attempts have seen a 32 Node Cluster Beowulf from the Boise State University.

However it would appear that a 120 node Cluster is currently being developed.

With the 32 node cluster costing roughly the same as a PC, this technology has certainly brought high powered computing into the reach of most people today and the applications going forward are huge for development of solutions.
