Performance of the track selection DNN in Run 3
/CMS Collaboration
The DP-Note describes the DNN used for track selection in Run3 and shows the physics performance in Run3 simulation. The tracking efficiency, fake rate and duplicate rate are shown as a function of p$_T$, $\eta$, pileup for $t\bar{t}$ events and as a function of the track displacement for stop-antistop events..

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. [...]

Luminosity monitoring with Z counting in early 2022 data
/CMS Collaboration
Measurements of the efficiency corrected Z boson rates for luminosity determination are presented using proton-proton collisions at $\sqrt{s} = 13.6$\,TeV recorded in the year 2022 with the CMS detector. The Z boson candidates decaying into a muon pair are selected. [...]
