Algorithms and Software for Event Reconstruction in the RICH, TRD and MUCH Detectors of the CBM Experiment

摘要

The Compressed Baryonic Matter (CBM) experiment at the future FAIR facility at Darmstadt will measure dileptons emitted from the hot and dense phase in heavy-ion collisions. Very fast event recon struction is extremely important for CBM because of the huge amount of data which has to be handled. In this contribution the parallel event re construction algorithms in the Ring Imaging CHerenkov detector, Transi tion Radiation Detector and muon system are presented. Modern CPUs have two features, which enable parallel programming. First, the SSE technology allows using the SIMD execution model. Second, multi core CPUs enable to use multithreading. Both features were implemented in the reconstruction software. Simulation results show a significant speed up factor.
