/CMS Collaboration
We present an interactive game for up to seven players that demonstrates the challenges of on-line event selection at the Compact Muon Solenoid (CMS) experiment to the public. The game - in the shape of a popular classic pinball machine - was conceived and prototyped by an interdisciplinary team of graphic designers, physicists and engineers at the CMS Create hackathon in 2016.

The Phase-2 Upgrade of the CMS Data Acquisition
/ CMS Collaboration
The High Luminosity LHC (HL-LHC) will start operating in 2027 after the third Long Shutdown (LS3), and is designed to provide an ultimate instantaneous luminosity of $7.5\times10^{34}$ cm$^{-2}$ s$^{-1}$, at the price of extreme pileup of up to 200 interactions percrossing. The number of overlapping interactions in HL-LHC collisions, their density, and the resulting intense radiation environment, warrant an almost complete upgrade of the CMS detector.The upgraded CMS detector will be read out by approximately 50 thousand high-speed front-end optical links at an unprecedented data rate of up to 80~Tb/s,for an average expected total event size of approximately 7-10 MB.Following the present established design, the CMS trigger and data acquisition system will continue to feature two trigger levels, with only one synchronous hardware-based Level-1 Trigger (L1),consisting of custom electronic boards and operating on dedicated data streams, and a second level, the High Level Trigger (HLT), using software algorithms running asynchronously on standard processors and making use of the full detector data to select events for offline storage and analysis.The upgraded CMS data acquisition system will collect data fragments for Level-1 accepted events from the detector back-end modules at a rate up to 750 kHz, aggregate fragments corresponding to individual Level-1 accepts into events, and distribute them to the HLT processors where they will be further selected.

A scalable online monitoring system based on Elasticsearch for distributed data acquisition in CMS
/ Andre, Jean-Marc (Fermilab) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Brummer, Philipp (CERN ; KIT, Karlsruhe) ; Chaze, Olivier (CERN) ; Cittolin, Sergio (UC, San Diego) ; da Silva Gomes, Diego (CERN) ; Darlea, Georgiana-Lavinia (MIT) ; Deldicque, Christian (CERN) ; Demiragli, Zeynep (MIT) et al.
The part of the CMS Data Acquisition (DAQ) system responsible for data readout and event building is a complex network of interdependent distributed applications. To ensure successful data taking, these programs have to be constantly monitored in order to facilitate the timeliness of necessary corrections in case of any deviation from specified behaviour.
