GPU Implementations of Online Track Finding Algorithms at PANDA — •Andreas Herten1, Tobias Stockmanns1, James Ritman1, and Mohammad Al-Turany2 — 1Institut für Kernphysik, Forschungszentrum Jülich GmbH — 2GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt
The PANDA experiment is a hadron physics experiment that will investigate antiproton annihilation in the charm quark mass region. The experiment is now being constructed as one of the main parts of the FAIR facility.
At an event rate of 2·107 /s a data rate of 200 GB/s - 1 TB/s is expected. A reduction of three orders of magnitude is needed in order to save the data for further offline analysis. Since signal and background processes at PANDA have similar signatures, no hardware-level trigger is forseen for the experiment. Instead, a fast online event reconstruction is substituting this element. We investigate the possibility of using graphics processing units (GPUs) for this task.
This talk shows advances in the implementations of fast tracking algorithms for GPUs to be used at PANDA.
