Design and engineering of a simplified workflow execution for the MG5aMC event generator on GPUs and vector CPUs
/ Valassi, Andrea (CERN) ; Roiser, Stefan (CERN) ; Mattelaer, Olivier (Louvain U.) ; Hageboeck, Stephan (CERN)
Physics event generators are essential components of the data analysis software chain of high energy physics experiments, and important consumers of their CPU resources. Improving the software performance of these packages on modern hardware architectures, such as those deployed at HPC centers, is essential in view of the upcoming HL-LHC physics programme. [...]

Developments in Performance and Portability for MadGraph5_aMC@NLO
/ Valassi, Andrea (CERN) ; Childers, Taylor (Argonne (main)) ; Field, Laurence (CERN) ; Hageboeck, Stefan (CERN) ; Hopkins, Walter (Argonne (main)) ; Mattelaer, Olivier (Cathol. U. Louvain (main)) ; Nichols, Nathan (Argonne (main)) ; Roiser, Stefan (CERN) ; Smith, David (CERN)
Event generators simulate particle interactions using Monte Carlo techniques, providing the primary connection between experiment and theory in experimental high energy physics. These software packages, which are the first step in the simulation worflow of collider experiments, represent approximately 5 to 20% of the annual WLCG usage for the ATLAS and CMS experiments. [...]
