The new centre of mass energy and high luminosity conditions during Run 2 of the Large Hadron Collider impose ever more demanding constraints on the ATLAS online trigger reconstruction and selection system. To cope with these conditions, the hardware-based Level-1 trigger now includes a Topological Processor and the software-based High Level Trigger has been redesigned, merging the two previously ...

Although the flagship of CERN physics is the Large Hadron Collider (LHC), the CERN scientific programme is varied and diversified. It extends to low-energy nuclear physics, antiproton experimentation and fixed target experiments at intermediate energies. After the Higgs discovery in 2012, an intense activity has started to prepare for the future. While the high priority still remains the LHC with ... More

The data processing and simulation needs of the ATLAS experiment at LHC grow continuously, as more data are collected and more use cases emerge. For data processing the ATLAS experiment adopted the data transformation approach, where software applications transform the input data into outputs. In the ATLAS production system, each data transformation is represented by a task, a collection of many j ... More

Electron and photon triggers covering transverse energies from 5 GeV to several TeV are essential for signal selection in a wide variety of ATLAS physics analyses to study Standard Model processes and to search for new phenomena. Final states including leptons and photons had, for example, an important role in the discovery and measurement of the Higgs particle. Dedicated triggers are also us ... More

The design and performance of the ATLAS Inner Detector (ID) trigger algorithms running online on the high level trigger (HLT) processor farm with the early LHC Run 2 data are discussed. During the 2013-15 LHC shutdown, the HLT farm was redesigned to run in a single HLT stage, rather than the two-stage (Level 2 and Event Filter) used in Run 1. This allowed a redesign of the HLT ID tracking algorith ... More

The Worldwide LHC Computing Grid (WLCG) has been in production for more than 10 years supporting the preparations for, and then the first run of the LHC. It has shown itself to be one of the pillars of the infrastructure necessary to enable the rapid production of physics results from the LHC, and has been in constant use at a very high load since its first introduction. However, even from the ... More

The ATLAS experiment collects billions of events per year of data-taking, and processes them to make them available for physics analysis in several different formats. An even larger amount of events is in addition simulated according to physics and detector models and then reconstructed and analysed to be compared to real events. The EventIndex is a catalogue of all events in each production stage ... More

The availability of cheap, easy-to-use sync-and-share cloud services has split the scientific storage world into the traditional big data management systems and the very attractive sync-and-share services. With the former, the location of data is well understood while the latter is mostly operated in the Cloud, resulting in a rather complex legal situation. Beside legal issues, those two worlds h ...
