Generalizing mkFit and its Application to HL-LHC / CMS Collaboration
MkFit is an implementation of the Kalman filter-based track reconstruction algorithm that exploits both thread- and data-level parallelism. In the past few years the project transitioned from the R\&D; phase to deployment in the Run-3 offline workflow of the CMS experiment. [...]

Vectorization of CMSSW offline software / Gartung, Patrick Elmo (Fermilab) /CMS Collaboration
Vectorization in CMSSW applicationsThe CMS experiment has been utilizing vectorization, or SIMD, in parts of its data processing applications for over a decade. On x86 platforms the vectorization level is still SSE3. [...]

CMSSW Scaling Limits on Many-Core Machines / Jones, Christopher (Fermilab) ; Gartung, Patrick (Fermilab) /CMS Collaboration
Today the LHC offline computing relies heavily on CPU resources, despite the interest in compute accelerators, such as GPUs, for the longer term future. The number of cores per CPU socket has continued to increase steadily, reaching the levels of 64 cores (128 threads) with recent AMD EPYC processors, and 128 cores on Ampere Altra Max ARM processors.

Development of the CMS detector for the CERN LHC Run 3 / CMS Collaboration
Since the initial data taking of the CERN LHC, the CMS experiment has undergone substantial upgrades and improvements. This paper discusses the CMS detector as it is configured for the third data-taking period of the CERN LHC, Run 3, which started in 2022. [...]

Speeding up the CMS track reconstruction with a parallelized and vectorized Kalman-filter-based algorithm during the LHC Run 3 / CMS Collaboration
One of the most challenging computational problems in the Run 3 of the Large Hadron Collider (LHC) and more so in the High-Luminosity LHC (HL-LHC) is expected to be finding and fitting charged-particle tracks during event reconstruction. [...]

Using the CMS Threaded Framework In A Production Environment / Jones, C D (Fermilab) ; Contreras, L (Fermilab) ; Gartung, P (Fermilab) ; Hufnagel, D (Fermilab) ; Sexton-Kennedy, L (Fermilab) /CMS
During 2014, the CMS Offline and Computing Organization completed the necessary changes to use the CMS threaded framework in the full production environment. We will briefly discuss the design of the CMS Threaded Framework, in particular how the design affects scaling performance. [...]

A New Boson with a Mass of 125 GeV Observed with the CMS Experiment at the Large Hadron Collider / CMS Collaboration
The Higgs boson was postulated nearly five decades ago within the framework of the standard model of particle physics and has been the subject of numerous searches at accelerators around the world. Its discovery would verify the existence of a complex scalar field thought to give mass to three of the carriers of the electroweak force—the W+, W–, and Z0 bosons—as well as to the fundamental quarks and leptons. [...]

Observation of a new boson at a mass of 125 GeV with the CMS experiment at the LHC / CMS Collaboration
Results are presented from searches for the standard model Higgs boson in proton-proton collisions at $\sqrt{s}$=7 and 8 TeV in the CMS experiment at the LHC, using data samples corresponding to integrated luminosities of up to 5.1 inverse femtobarns at 7 TeV and 5.3 inverse femtobarns at 8 TeV. The search is performed in five decay modes: $\gamma\gamma$, ZZ, WW, $\tau^+ \tau^-$, and $b\bar{b}$. [...]

Commissioning and performance of the CMS pixel tracker with cosmic ray muons / CMS Collaboration
The pixel detector of the Compact Muon Solenoid experiment consists of three barrel layers and two disks for each endcap. The detector was installed in summer 2008, commissioned with charge injections, and operated in the 3.8 T magnetic field during cosmic ray data taking. [...]

Measurement of the muon stopping power in lead tungstate / CMS Collaboration
A large sample of cosmic ray events collected by the CMS detector is exploited to measure the specific energy loss of muons in the lead tungstate (PbWO$_4$) of the electromagnetic calorimeter. The measurement spans a momentum range from 5 GeV/$c$ to 1 TeV/$c$. [...]
