The PANDA experiment is a new hadron physics experiment currently being built at FAIR, Darmstadt (Germany). PANDA will study fixed-target collisions of antiprotons of 1 5 GeV/ c to 15 GeV/ c momentum with protons and nuclei at a rate of 20 million events per second. To distinguish between background and signal events, PANDA will utilize a novel data acquisition technique. The experiment uses a sophisticated software-based event filtering scheme involving the reconstruction of the whole incoming data stream in real- time to trigger its data taking. Algorithms for online track reconstruction are essential for this task. We investigate algorithms running on GPUs to solve PANDA’s real-time computing challenges
