Extending the TICL Framework to the CMS Barrel Calorimeters — •Alessandro Brusamolino1, Felice Pantaleo2, Marco Rovere2, and Markus Klute1 — 1Institut für Experimentelle Teilchenphysik, Karlsruhe Institute of Technology, Karlsruhe, Germany — 2CERN, Geneva, Switzerland
The Iterative CLustering (TICL) is a reconstruction framework which is being developed for the High-Granularity Calorimeter (HGCal), a sampling calorimeter which will be installed in the CMS endcaps for the HL-LHC phase. These reconstruction algorithms aim at reconstructing physical objects starting from 5D hits (position, energy and time), returning particle properties and identification probabilities, and are designed with heterogeneous computing in mind, in order to speed up reconstruction time. In this talk we give an overview of the first efforts in extending TICL to the barrel calorimeters and present the benefits of having the same framework used across all of the CMS calorimeters, both in terms of physics and computing performances. Moreover, we discuss the need for a revision of the data structures used in the reconstruction software, in order to run it in an efficient way, fully exploiting the capabilities of parallel architectures.
