This training course will focus on the foundations of “Big Data” processing by introducing the Hadoop distributed computing architecture and providing an introductory level tutorial for Big Data analysis using Hadoop, Rhadoop, and R libraries parallel, doParallel, foreach and Rmpi. Although online, the course will be hands-on, allowing participants to work interactively on real data on the High Performance Computing environment of the University of Ljubljana and on the Vienna Scientific Cluster.
