DESCRIPTION:Speakers: Felice Pantaleo (CERN)\, Dorothea Vom Bruch (LPNHE P
 aris\, CNRS)\n\nThe CMS and LHCb experiments at CERN are moving towards he
 terogeneous and massively parallel computing architectures for processing 
 and reducing data in real-time. However\, the different physics environmen
 ts of the two experiments affect the design of the heterogeneous event sel
 ection systems. \n\nThe implementation of an accelerated software trigger
  system faces multiple challenges: from the software scheduling to the int
 egration with the rest of the DAQ system\, from the reconstruction algorit
 hms\, which have to be designed to run efficiently on GPUs\, to the trigge
 r farm infrastructure. \n\nThe speakers will describe how CMS and LHCb re
 designed some of the most time consuming algorithms in their online recons
 truction (among which are tracking and calorimeter local reconstruction) t
 o leverage the GPU’s massively parallel architecture\, allowing both the
  experiments to increase their physics potential with sustainable costs.\n
 \nIn addition\, the speakers will present and compare the approaches\, con
 straints and trade-offs motivating the design of the CMS and LHCb heteroge
 neous online event reconstruction and selection systems planned for LHC Ru
 n-3.\n\nZoom: https://cern.zoom.us/j/94344476291\n\nhttps://indico.cern.c
