New software technologies in the LHCb Simulation

Abstract Monte Carlo simulations are key to the design and commissioning of new detectors as well interpretation physics measurements. The amount simulated samples required for Run 3 program LHCb experiment will increase significantly from 2022 onward match in data collected with respect 1 2 operation. A version Gauss simulation framework has been developed better accommodate techniques software technologies produce necessary within computing resources allocated next few years. It provides specific functionality while generic infrastructure encapsulated an experiment-independent framework, GAUSSINO. latter combines GAUDI core GEANT4 toolkit fully exploits their multi-threading capabilities. Fast interface is latest feature being GAUSSINO interact giving possibility replacing its detailed description processes extensive palette fast models a sub-detector. facility ease production training datasets also introduced.
