Description
Event Generators simulate particle interactions using Monte Carlo processes providing the primary connection between experiment and theory in experimental high energy physics. These make up the first step in the simulation workflow of collider experiments, representing 10-20% of the annual WLCG usage for the ATLAS and CMS experiments. With computing architectures becoming more heterogeneous, it is important to ensure these key software frameworks can be run on future systems, large and small. Progress on advancing the Madgraph_aMC@NLO event generator to utilize hybrid architectures, i.e. CPU with accelerators, will be discussed. In this case, the leading-order code generation toolkit has been expanded to generate matrix element calculations using C++ vector instructions and in CUDA, Kokkos, Alpaka, and SYCL. Performance will be reported in terms of matrix element calculations per time on NVidia, Intel, and AMD devices.
