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. [...]

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. [...]

Bringing heterogeneity to the CMS software framework / Bocci, Andrea (CERN) ; Dagenhart, David (Fermilab) ; Innocente, Vincenzo (CERN) ; Jones, Christopher (Fermilab) ; Kortelainen, Matti (Fermilab) ; Pantaleo, Felice (CERN) ; Rovere, Marco (CERN) /CMS Collaboration
The advent of computing resources with co-processors, for example Graphics Processing Units (GPU) or Field-Programmable Gate Arrays (FPGA), for use cases like the CMS High-Level Trigger (HLT) or data processing at leadership-class supercomputers imposes challenges for the current data processing frameworks. These challenges include developing a model for algorithms to offload their computations on the co-processors as well as keeping the traditional CPU busy doing other work. [...]

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. [...]

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. [...]

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. [...]

Running GPU-enabled CMSSW workflows through the production system / Koraka, Charis Kleio (Wisconsin U., Madison) /CMS Collaboration
The CMS experiment at CERN accelerates several stages of its online reconstruction by making use of GPU resources at its High Level Trigger (HLT) farm for LHC Run 3. Additionally, during the past years, computing resources available to the experiment for performing offline reconstruction, such as Tier-1 and Tier-2 sites, have also started to integrate accelerators into their systems.

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).
