Optimisation of GPU Accelerated Algorithms for Track Finding in Particle Physics — •Petr Fiedler, André Sopczak, and Pavel Tvrdik — CTU in Prague

Track finding in particle physics has been an increasing challenge over the past decades because the intensities of collisions in state-of-the-art particle colliders have increased enormously. One of the track reconstruction steps is the track finding. For this, track seeds are determined and the tracks are successively reconstructed by adding more measurements. We explain the main ideas of the state-of-the-art GPU-accelerated implementation of the track finding algorithm and describe several optimisations focusing on an early elimination of fake tracks.
