Performance of Heterogeneous Algorithm Scheduling in CMSSW / Bocci, Andrea (CERN) ; Jones, Christopher Duncan (Fermilab) ; Kortelainen, Matti Johannes (Fermilab) /CMS Collaboration
The CMS experiment started to utilize Graphics Processing Units (GPU) to accelerate the online reconstruction and event selection running on its High Level Trigger (HLT) farm in the 2022 data taking period. The projections of the HLT farm to the High-Luminosity LHC foresee a significant use of compute accelerators in the LHC Run 4 and onwards in order to keep the cost, size, and power budget of the farm under control. [...]

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. [...]

Stitched Together Transitioning CMS to a Hierarchical Threaded Framework / Jones, Christopher Duncan (Fermilab) ; Sexton-Kennedy, Elizabeth (Fermilab) /CMS Collaboration
Modern computing hardware is transitioning from using a single high frequency complicated computing core to many lower frequency simpler cores. As part of that transition, hardware manufacturers are urging developers to exploit concurrency in their programs via operating system threads. [...]

Using OpenMP for HEP Framework Algorithm Scheduling / Jones, Christopher Duncan (Fermilab) /CMS Collaboration
The OpenMP standard is the primary mechanism used at high performance computing facilities to allow intra-process parallelization. In contrast, many HEP specific software packages (such as CMSSW, GaudiHive, and ROOT) make use of Intels Threading Building Blocks (TBB) library to accomplish the same goal. [...]

Implementing Concurrent Non-Event Transitions in CMS / Jones, Christopher Duncan (Fermilab) /CMS Collaboration
Since the beginning of the LHC Run 2 in 2016 the CMS data processing framework, CMSSW, has been running with multiple threads during production of data and simulation via the use of Intels Thread Building Blocks (TBB) library. The TBB library utilizes tasks as concurrent units of work. [...]

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 $b\bar{b}$. [...]

Multicore-aware applications in CMS / Jones, Christopher Duncan (Fermilab) ; Elmer, Peter (Princeton U.) ; Sexton, Liz (Fermilab) ; Green, Chris (Fermilab) ; Baldooci, Andrew (Fermilab) /CMS Collaboration
One of the significant trends of recent years has been the move towards multicore CPU's with ever increasing numbers of cores. CMS has been preparing multicore aware applications that rely on "multi-processing", namely the sharing of memory between processes forked from a single parent process. [...]

Event Displays for the Visualization of CMS Events / Jones, Christopher Duncan (Fermilab) /CMS Collaboration
During the last year the CMS experiment engaged in consolidation of its existing event display programs. The core of the new system is based on the Fireworks event display program which was by-design directly integrated with the CMS Event Data Model (EDM) and the light version of the software framework (FWLite).

Physics Analysis Tools for the CMS experiment at LHC / Fabozzi, Francesco (INFN and Univ. Napoli, Italy) ; Jones, Christopher Duncan ; Hegner, Benedikt ; Lista, Luca /CMS Offline Project
The CMS experiment is expected to start data taking during 2008, and large data samples, of the Peta-bytes scale, will be produced each year. The CMS Physics Tools package provides the CMS physicist with a powerful and flexible software layer for analysis of these huge datasets that is well integrated in the CMS experiment software. [...]
