Improving Performance Portability of the Procedurally Generated High Energy Physics Event Generator MadGraph Using SYCL / Nichols, Nathan S (Argonne (main)) ; Childers, J Taylor (Argonne (main)) ; Burch, Tyler James (Argonne (main)) ; Field, Laurence (CERN)
Event Generators are essential tools for simulating Standard Model particle interactions, representing the initial step in modeling proton-proton collisions in the Large Hadron Collider (LHC) at CERN. Traditionally relying on a few algorithms like MadGraph5_aMC@NLO, there is a pressing need for enhanced portability across diverse computing platforms. [...]

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. [...]
