  • The physics program of the LHCb experiment depends on an efficient and precise reconstruction of the primary vertices produced by proton-proton collisions. The LHCb Upgrade detector, starting to take data in 2021 with a fully software- based trigger, requires an online reconstruction at a rate of 30 MHz, necessitating fast vertex finding algorithms. We present a new approach to vertex reconstruction and its parallelized implementation on x86 and GPU architectures.
