Wisconsin, Madison (main)) ; Heinrich, Lukas (Munich, Max Planck Inst.) ; Liu, Yang (SYSU, Guangzhou) ; Mečionis, Audrius (CERN) ; Moisieienkov, Vladyslav (CERN) ; Šimko, Tibor (CERN) ; Stark, Giordon (UC, Santa Cruz, Inst. Part. Phys.) ; García, Marco Vidal (CERN)
In this paper we describe the development of a streamlined framework for large-scale ATLAS pMSSM reinterpretations of LHC Run-2 analyses using containerised computational workflows. The project is looking to assess the global coverage of BSM physics and requires running O(5k) computational workflows representing pMSSM model points. [...]

Easing the Control System Application Development for CMS Detector Control System with Automatic Production Environment Reproduction
/ Papakrivopoulos, Ioannis (Natl. Tech. U., Athens ; CERN) ; Bakas, Georgios (Natl. Tech. U., Athens) ; Behrens, Ulf (Rice U.) ; Branson, James (UC, San Diego) ; Brummer, Philipp (CERN ; KIT, Karlsruhe) ; Cittolin, Sergio (UC, San Diego) ; Da Silva Gomes, Diego (CERN ; Fermilab) ; Darlea, Georgiana-Lavinia (MIT) ; Deldicque, Christian (CERN) ; Dobson, Marc (CERN) et al.
The Detector Control System (DCS) is one of the main pieces involved in the operation of the Compact Muon Solenoid (CMS) experiment at the LHC. The system is built using WinCC Open Architecture (WinCC OA) and the Joint Controls Project (JCOP) framework which was developed on top of WinCC at CERN. [...]

Scalable Declarative HEP Analysis Workflows for Containerised Compute Clouds
/ Šimko, Tibor (CERN) ; Heinrich, Lukas Alexander (CERN) ; Lange, Clemens (CERN) ; Lintuluoto, Adelina Eleonora (CERN ; Helsinki U.) ; MacDonell, Danika Marina (Victoria U.) ; Mečionis, Audrius (CERN) ; Rodríguez Rodríguez, Diego (CERN) ; Shandilya, Parth (CERN ; LNM Inst. Info. Tech.) ; Vidal García, Marco (CERN)
We describe a novel approach for experimental High-Energy Physics (HEP) data analyses that is centred around the declarative rather than imperative paradigm when describing analysis computational tasks. The analysis process can be structured in the form of a Directed Acyclic Graph (DAG), where each graph vertex represents a unit of computation with its inputs and outputs, and the graph edges describe the interconnection of various computational steps. [...]

The Data Acquisition (DAQ) system of the Compact Muon Solenoid (CMS) experiment at the LHC is a complex system responsible for the data readout, event building and recording of accepted events. Its proper functioning plays a critical role in the data-taking efficiency of the CMS experiment. [...]

First measurements with the CMS DAQ and Timing Hub prototype-1

The DAQ and Timing Hub is an ATCA hub board designed for the Phase-2 upgrade of the CMS experiment. In addition to providing high-speed Ethernet connectivity to all back-end boards, it forms the bridge between the sub-detector electronics and the central DAQ, timing, and trigger control systems.

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.

Operational experience with the new CMS DAQ-Expert
/ Sakulin, Hannes (CERN) ; Andre, Jean-Marc (Fermilab) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Brummer, Philipp (CERN ; KIT, Karlsruhe) ; Cittolin, Sergio (UC, San Diego) ; da Silva Gomes, Diego (CERN) ; Darlea, Georgiana-Lavinia (MIT) ; Deldicque, Christian (CERN) ; Demiragli, Zeynep (MIT) et al.
The data acquisition (DAQ) system of the Compact Muon Solenoid (CMS) at CERN reads out the detector at the level-1 trigger accept rate of 100 kHz, assembles events with a bandwidth of 200 GB/s, provides these events to the high level-trigger running on a farm of about 30k cores and records the accepted events. Comprising custom-built and cutting edge commercial hardware and several 1000 instances of software applications, the DAQ system is complex in itself and failures cannot be completely excluded. [...]
