I have worked extensively with the Raspberry Pi. From building a 70 node cluster for distributed computing to building an IoT based system for Gas Leak Detection, I have used the Raspberry Pis. They have performed flawlessly. One thing I wish I had when I was working on these projects were some kind of guidance […]
The popularity behind Raspberry pi 3 model B projects is due to the upgraded hardware on the device. It now comes with a wifi module, a quad-core CPU, and 1 GB of RAM. This makes the Pi much more powerful than its predecessors. Another factor for the rise in popularity is its low price. Do […]
Congratulations on getting a Raspberry Pi. I am guessing you are building something cool with it and you want to get started. In this tutorial, you will learn about installing Raspbian OS and initiating a desktop environment on your raspberry pi. You might be trying to build a Raspberry Pi supercomputer or a server or […]
Though the Internet is a vast resource for getting a Raspberry pi supercomputer up and running, there is no full set of errors that you can refer to when you’re stuck. Many times it happens that the same error on two different clusters can have two totally different meanings, making it even more difficult to […]
Building a Raspberry Pi cluster is hard work and requires a lot of time and patience. My team and I built a 70 node cluster and this is one of the most amazing Raspberry pi projects that I have worked on. Distributed programming is a must on clusters and for our cluster we chose the MPI4py […]
Making a Raspberry Pi cluster requires an initial setup to be performed. Here I assume that the OS that is running is Raspbian. So once the cluster is built generally one Raspberry pi designated as the master node controls the functionality of all the other nodes. So this post deals with how the master node […]
In the process of building a Raspberry Pi cluster, I came across a few libraries for inter-node communication. I was facing some issues while using these libraries and the errors weren’t one of the common ones associated with Raspberry Pis. These libraries made use of a feature called Hard Floating Point computation and I wanted […]
The previous post demonstrates how we can go about building mpi4py so that we can write and run python programs using MPICH. So once the mpi4py is built and is installed, it has to be tested. Here, it is assumed that you have a machinefile that stores the IP addresses of all the nodes in […]
