We provide solutions to this problem by focusing on two major components of general-purpose event generators: The PDF evaluator and the matrix-element generator. For a typical production setup in the ATLAS experiment, we show that the two can consume about 80% of the total runtime. Using NLO simulations of $pp\\to\\ell^+\\ell^-+\\text{jets}$ and $pp\\to t\\bar{t}+\\text{jets}$ as an example, we demonstrate that the computing footprint of LHAPDF and Sherpa can be ","authors_text":"Andy Buckley, Christian G\\\"utschow, Enrico Bothmann, Ilektra A.
