CERN openlab is a unique public-private partnership between CERN and leading IT companies and research institutes. In the fall of 2015 CERN openlab and its partner Intel organised a Code Modernization Competition. The goal of the competition was to speed up the performance of a given piece of code, by making use of all possible features of the latest Intel CPU’s and co-processors. This competition was a great success and the results were quite remarkable and unexpected. In this presentation I will highlight the competition's results and the lessons learned, and more importantly the setting up of an own permanent CERN openlab coding competition environment, to be used to let students and professionals alike challenge each other's coding prowess.
