We present a scalable technique for the simulation of collider events with multijet final states, based on an improved parton-level event file format and scalable $I / O$ . The method is implemented for both leading- and next-to-leading-order QCD calculations. We perform a comprehensive analysis of the computing performance and validate our new framework using Higgs-boson plus multijet production with up to seven jets. We make the resulting code base available for public use. Published by the American Physical Society 2024
