Speeding up Madgraph5 aMC@NLO through CPU vectorization and GPU offloading: towards a first alpha release Open
The matrix element (ME) calculation in any Monte Carlo physics event generator is an ideal fit for implementing data parallelism with lockstep processing on GPUs and vector CPUs. For complex physics processes where the ME calculation is th…

A Grand Scan of the pMSSM Parameter Space for Snowmass 2021 Open
We present a flexible framework for interpretation of SUSY sensitivity studies for future colliders in terms of the phenomenological minimal supersymmetric standard model (pMSSM). We perform a grand scan of the pMSSM 19-dimensional paramet…
