 A first look at early 2022 proton-proton collisions at $\sqrt{s}\ =\ 13.6$ TeV for heavy-flavor jet tagging /CMS Collaboration Identification of jets stemming from heavy-flavor (bottom or charm) hadrons relies primarily on the inputs due to reconstruction of charged particle tracks and secondary vertices contained in these jets. Thus, it is crucial to study the data vs. [...] CMS-DP-2023-012; CERN-CMS-DP-2023-012.- Geneva : CERN, 2023 - 32 p. Fulltext: PDF;

 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.
