Common and community software packages, such as ROOT, Geant4 and event generators have been a key part of the LHC's success so far and continued development and optimisation will be critical in the future. The challenges are driven by an ambitious physics programme, notably the LHC accelerator upgrade to high-luminosity, HL-LHC, and the corresponding detector upgrades of ATLAS and CMS. In this document we address the issues for software that is used in multiple experiments (usually even more… Expand
Speeding up MadGraph5_aMC@NLO
TLDR
Two new optimisations implemented in MadGraph5_aMC@NLO are designed to speed-up the computation of leading-order processes (for any model) by implementing a new method to evaluate the squared matrix element, dubbed helicity recycling, which results in factor of two speed-ups. Expand
