CERN, the European Organization for Nuclear Research, is the world’s largest particle physics laboratory and home of the Large Hadron Collider (LHC), the world’s most powerful accelerator providing research facilities for High Energy Physics researchers across the globe. In the first run of the accelerator, resulting in the Nobel prize-winning discovery of the Higgs boson, the LHC experiments generated up to 27 PB of data per year, a rate which has increased to over 50PB after 2016. In processing and analysing this data the experiments run more than 2 million jobs per day on the global distributed computing infrastructure federating around 170 computer centres worldwide.
