Real-time track reconstruction with GPUs — •Dorothea vom Bruch — Aix Marseille Univ, CNRS/IN2P3, CPPM, Marseille, France

As the instantaneous luminosity of high energy physics (HEP) experiments increases, so does the data rate produced. To process these data streams in real time, available computing hardware has to be exploited optimally. In addition, increasingly more global event information is needed for efficient data selection, such as the reconstruction of charged particle trajectories at the earliest possible stages of the selection chain. I will discuss how the multi-core architecture of graphics processing units (GPUs) is used in several HEP experiments to cope with the computing challenge of particle reconstruction in real-time.
