Welcome to the WRENCH-Pedagogic-Modules,

The goal of these pedagogic modules is for students to achieve learning objectives in the area of distributed computing, in the context of scientific workflows, via hands-on experiments. This is achieved through a set of “activities” that explore, at first elementary and later sophisticated, concepts and techniques. All these activities entail simulating workflow executions using the WRENCH simulation framework.

Each activity can be viewed by clicking on the menu button located at the top left hand corner of the screen. Before proceeding to the first section, What is this about?, ensure that you are using one of the web browsers specified below and have Docker OR Vagrant installed on your machine.
