If you are interested in building your very own Raspberry Pi cluster, combining multiple Raspberry Pi mini PCs together to form one supercomputer. You may be interested in a article published to the official MagPi magazine website detailing how to get started and assemble your Raspberry Pi cluster.
The operating system used to power the Raspberry Pi cluster is Raspbian Buster Lite which is used to control the four Raspberry Pi 4B computers combined in a four-berth chassis. “For the cluster to work, each worker node needs to be able to talk to the master node without needing a password to log in. To do this, we use SSH keys. This can be a little laborious, but only needs to be done once.”
“The concept of computer ‘clusters’ (many computers working together as one) is nothing new, but when you have a device as affordable as Raspberry Pi, you can start to rival much more expensive systems by using several in parallel. Here, we’ll learn how to make a cluster computer from a lot of little computers.”
“A cluster of Raspberry Pi computers can start with as little as two and grow into hundreds. For our project, we’re starting with a modest four. Each one, known as a ‘node’, will carry out part of our task for us and they all work in parallel to produce the result a lot quicker than a single node ever could. Some nice ‘cluster cases’ are available, and we start here by assembling our Raspberry Pi 4B computers into a four-berth chassis. Many different configurations are available, including fan cooling.”
