 Some Theoretical Aspects of Quantum Electrodynamics / Yennie, D R (Cornell U., LNS) In this talk I want to restrict myself to topics I think are of most immediate interest to experimentalists. While there is interesting work going on at a more fundamental level in quantum electrodynamics, at the present time this work seems to be mainly concerned with the internal properties and consistency of the subject and it does not seem to have any immediate relevance to experiment.

 What Have We Learned About Elementary Particles from Photon and Electron Interactions? / Drell, S D (SLAC ; Stanford U.) In trying to write this report I find myself in limbo. I am announced as speaking on "What We Have Learned” at the Opening of this conference prior to the presentation of many new and more precise experimental results — and in particular before the disclosure of first results from SLAC at significantly higher energies and momentum transfers than heretofore available.

 New approaches for track reconstruction in LHCb’s Vertex Locator / Albrecht, Johannes (Tech. U., Dortmund (main)) ; Bourgeois, Dylan (Ecole Polytechnique, Lausanne) ; Coco, Victor (CERN) ; Couturier, Ben (CERN) ; Hasse, Christoph (Tech. U., Dortmund (main) ; CERN) ; Nolte, Niklas (CERN ; Tech. U., Dortmund (main)) ; Ponce, Sebastien (CERN) /LHCb Starting with Upgrade 1 in 2021, LHCb will move to a purely software-based trigger system. Therefore, the new trigger strategy is to process events at the full rate of 30MHz.

 Readout software for the ALICE integrated Online-Offline (O$^2$) system / Chapeland, Sylvain (CERN) ; Costa, Filippo (CERN) /ALICE ALICE (A Large Ion Collider Experiment) is a heavy-ion detector studying the physics of strongly interacting matter and the quark - gluon plasma at CERN’s LHC (Large Hadron Collider). During the second long shutdown of the LHC, the ALICE detector will be upgraded to cope with an interaction rate of 50 kHz in Pb–Pb collisions, producing in the online computing system (O$^2$) a sustained input throughput of 3 TB/s.

 Data handling in the ALICE O$^2$ event processing / Richter, Matthias (CERN ; Oslo U.) ; Krzewicki, Mikolaj (Frankfurt U., FIAS) ; Eulisse, Giulio (CERN) The ALICE experiment at the Large Hadron Collider (LHC) at CERN is planned to be operated in a continuous data-taking mode in Run 3. This will allow to inspect data from all Pb-Pb collisions at a rate of 50 kHz, giving access to rare physics signals embedded in a large background.

 Towards the ALICE Online-Offline (O$^2$) control system / Mrnjavac, Teo (CERN) ; Chibante Barroso, Vasco (CERN) The ALICE Experiment at CERN LHC (Large Hadron Collider) is under preparation for a major upgrade that is scheduled to be deployed during Long Shutdown 2 in 2019-2020 and that includes new computing systems, called O$^2$ (Online-Offline). To ensure the efficient operation of the upgraded experiment along with its newly designed computing system, a reliable, high performance and automated control system will be developed with the goal of managing the lifetime of all the O$^2$ processes, and of handling the various phases of the data taking activity by interacting with the detectors, the trigger system and the LHC.

 The ProtoDUNE Single Phase detector control system / Kehrli, Antoine (CERN) ; Lehmann Miotto, Giovanna (CERN) ; Pons, Xavier (CERN) ; Ravat, Sylvain (CERN) ; Rodriguez, Manuel J (CERN ; Madrid, CIEMAT) This paper presents the Detector Control System (DCS) that has been designed and implemented for the NP04 experiment at CERN. NP04, alsoknown as protoDUNE Single Phase (SP), aims at validating the engineering processes and detector performance of a large Liquid Argon (LAr) Time Projection Chamber (TPC) in view of the DUNE experiment.

U., Munich (main)) ; Nový, Josef (CTU, Prague) ; Steffen, Dominik (Tech. U., Munich (main)) et al. Modern experiments demand a powerful and efficient Data Acquisition System (DAQ). The intelligent, FPGA-based Data Acquisition System (iF-DAQ) of the COMPASS experiment at CERN is composed of many processes communicating between each other.

 The design of a distributed key-value store for petascale hot storage in data acquisition systems / Cicalese, Danilo (CERN) ; Jereczek, Grzegorz (Unlisted, PL) ; Le Goff, Fabrice (CERN) ; Lehmann Miotto, Giovanna (CERN) ; Love, Jeremy (Argonne (main)) ; Maciejewski, Maciej (Unlisted, PL) ; Mommsen, Remigius K (Fermilab) ; Radtke, Jakub (Unlisted, PL) ; Schmiegel, Jakub (Unlisted, PL) ; Szychowska, Malgorzata (Unlisted, PL) Data acquisition systems for high energy physics experiments read-out terabytes of data per second from a large number of electronic components. They are thus inherently distributed systems and require fast online data selection, otherwise requirements for permanent storage would be enormous.
