An important area of HEP studies at the LHC currently concerns the need for more extensive and precise comparison data. Important tools in this realm are event reweighting and the evaluation of more precise next-to-leading order (NLO) physics processes via Monte Carlo (MC) event generators, especially in the context of the upcoming High Luminosity LHC phase. Current event generators need to improve their throughput for these studies. MadGraph5_aMC@NLO (MGaMC) is an event generator being used heavily by LHC experiments which has been accelerated considerably with a GPU and vector CPU port, but as of yet only for leading order processes. In this contribution, a prototype for event reweighting using the accelerated MGaMC software package, as well as plans for the implementation of NLO calculations, will be presented.
