 Commissioning CMS online reconstruction with GPUs /CMS Collaboration Building on top of the multithreading functionality that was introduced in Run-2, the CMS software framework (CMSSW) has been extended in Run-3 to offload part of the physics reconstruction to NVIDIA GPUs. The first application of this new feature is the High Level Trigger (HLT): the new computing farm installed at the beginning of Run-3 is composed of 200 nodes, and for the first time each one is equipped with two AMD Milan CPUs and two NVIDIA T4 GPUs.

 Tracker alignment performance in 2022 (addendum) /CMS Collaboration An accurate determination of the geometry of the inner tracking system of the CMS experiment, which comprises Silicon Pixel and Silicon Strip detectors, is of vital importance for a precise measurement of the momentum of charged particles and reconstruction of primary and secondary vertices. The process of determining the geometry parameters of the inner tracking system is called tracker alignment. [...] CMS-DP-2022-070; CERN-CMS-DP-2022-070.- Geneva : CERN, 2022 - 17 p. Fulltext: PDF;

 First Measurements of Muon Bending Angles in the CMS GE1/1-ME1/1 System /CMS Collaboration The achieving acceptable first level trigger rates for muons with reasonably low transverse momentum ($p_{T}$) thresholds is viable for the Compact Muon Solenoid (CMS) detector. In order to retain the current standalone muon trigger capability even with high occupancy in the endcap region during the high luminosity LHC (HL-LHC), the Gas Electron Multiplier (GEM) subdetector system was designed.
