Beowulf Cluster Setup

1. Introduction

A Beowulf cluster is a computer cluster of similar computers networked into a small local area network with libraries and programs installed which allow processing to be shared among them. The result is a high-performance parallel computing cluster from the inexpensive personal computer hardware.

This project aims to create a Beowulf Cluster which computes bigram analysis on a news data set. 2 virtual worker nodes and 1 virtual master node used for the cluster, all operating with Ubuntu Server 16.04.
