High precision calculations of particle physics at the NEMO cluster in Freiburg

Abstract

At the Large Hadron Collider of CERN in Geneva particles such as protons are smashed onto each other at the highest man-made energies ever. Despite being gigantic in size, custom-designed detectors are capable of recording billions of such collisions with high accuracy. To accompany these measurements, predictions of highest precision are required, for some of which it took the theory community more than 20 years to develop the necessary methods and techniques. We explain how these CPU intensive calculations have been adapted to run efficiently on the computing resources available within the bwHPC project and present the required tools and infrastructure we developed for this purpose.
