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 […]
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 […]
1 Introduction I had used putty for my amazing Raspberry Pi project. All my initial experiences have been combined into a set of points that detail on errors that occurred as well as how we ere able to solve it. Raspberry Pi: Make a Bench automation computer , is another awesome project to work on, if […]
1 Introduction MPI stands for Message passing interface. An implementation of MPI such as MPICH” or OpenMPI is used to create a platform to write parallel programs in a distributed system such as a Linux cluster with distributed memory. Generally the platform built allows programming in C using the MPI standard. So in order to […]
SSH stands for secure shell. It is an encrypted remote login protocol. Once it has been set up on each node, it can be used to communicate with various other nodes in that network. The main benefits of SSH are: SSH uses the RSA encryption algorithm to generate public and private keys, making intrusion extremely […]
