High energy physics particle detectors are large and complex devices with very demanding requirements at the level of signal to noise ratios, processing times and data throughput. The first stages of the data acquisition are hardware based while the last ones depend rather on software. Among the solutions to the problems posed by the requirements we may find the use of multi-core processors or maybe...
The online event reconstruction for the ALICE experiment at CERN requires processing capabilities to process central Pb-Pb collisions at a rate of more than 200 Hz, corresponding to an input data rate of about 25 GB/s. The reconstruction of particle trajectories in the Time Projection Chamber (TPC) is the most compute intensive step. The TPC online tracker implementation combines the principle of...
