Real-time Java to support the device property model
/ Cardin, Chloe (CERN) ; Galilée, Marc-Antoine (CERN) ; Garnier, Jean-Christophe (CERN) ; Krol, Kamil (CERN) ; Osinski, Maciej (CERN) ; Stanisz, Anita (CERN) ; Zerlauth, Markus (CERN)
Today's front-end controllers, which are widely used in CERNs controls environment, feature CPUs with high clock frequencies and extensive memory storage. Their specifications are comparable to low-end servers, or even smartphones. [...]

Renovation and extension of supervision software leveraging reactive streams
/ Galilée, Marc-Antoine (CERN) ; Calia, Andrea (CERN) ; Do, Janet (CERN) ; Fuchsberger, Kajetan (CERN) ; Garnier, Jean-Christophe (CERN) ; Krol, Kamil (CERN) ; Osinski, Maciej (CERN) ; Pocwierz, Maciej (CERN) ; Ribeiro, Tiago (CERN) ; Stanisz, Anita (CERN) et al.
Inspired by the recent developments of reactive programming and the ubiquity of the concept of streams in modern software industry, we assess the relevance of a reactive streams solution in the context of accelerator controls. The promise of reactive streams, to govern the exchange of data across asynchronous boundaries at a rate sustainable for both the sender and the receiver, is alluring to most data-centric processes of CERN's accelerators.

Tensorics - A Java library for manipulating multi-dimensional data
/ Fuchsberger, Kajetan (CERN) ; Calia, Andrea (CERN) ; Garnier, Jean-Christophe (CERN) ; Gorzawski, Arkadiusz (CERN) ; Hostettler, Michael (CERN) ; Krol, Kamil (CERN)
Accelerator control software often has to handle multi-dimensional data of physical quantities when aggregating readings from multiple devices (e.g. the reading of an orbit in the LHC). [...]

Smooth Migration of CERN Post Mortem Service to a Horizontally Scalable Service
/ Garnier, Jean-Christophe (CERN) ; Aguilera-Padilla, Cesar (CERN) ; Boychenko, Serhiy (CERN) ; Dragu, Matei (CERN) ; Galilée, Marc-Antoine (CERN) ; Koza, Mateusz (CERN) ; Krol, Kamil (CERN) ; Martins Ribeiro, Tiago (CERN) ; Orlandi, Roberto (CERN) ; Poeschl, Matthias (CERN) et al.
The Post Mortem service for CERNs accelerator complex stores and analyses transient data recordings of various equipment systems following certain events, like a beam dump or magnet quenches. The main purpose of this framework is to provide fast and reliable diagnostic to the equipment experts and operation crews to decide whether accelerator operation can continue safely or whether an intervention is required.

Towards a Second Generation Data Analysis Framework for LHC Transient Data Recording
/ Boychenko, Serhiy (CERN) ; Aguilera-Padilla, Cesar (CERN) ; Dragu, Matei (CERN) ; Galilée, Marc-Antoine (CERN) ; Garnier, Jean-Christophe (CERN) ; Koza, Mateusz (CERN) ; Krol, Kamil (CERN) ; Orlandi, Roberto (CERN) ; Poeschl, Matthias (CERN) ; Ribeiro, Tiago (CERN) et al.
During the last two years, CERNs Large Hadron Collider (LHC) and most of its equipment systems were upgraded to collide particles at an energy level twice higher compared to the first operational period between 2010 and 2013. System upgrades and the increased machine energy represent new challenges for the analysis of transient data recordings, which have to be both dependable and fast. [...]

Second Generation LHC Analysis Framework: Workload-based and User-oriented Solution
/ Boychenko, Serhiy (CERN) ; Aguilera-Padilla, Cesar (CERN) ; Galilée, Marc-Antoine (CERN) ; Garnier, Jean-Christophe (CERN) ; Gorzawski, Arkadiusz (CERN) ; Krol, Kamil (CERN) ; Makai, Jozsef (CERN) ; Osinski, Maciej (CERN) ; Poeschl, Matthias (CERN) ; Rela, Mario (Coimbra U.) et al.
Consolidation and upgrades of accelerator equipment during the first long LHC shutdown period enabled particle collisions at energy levels almost twice higher compared to the first operational phase. Consequently, the software infrastructure providing vital information for machine operation and its optimisation needs to be updated to keep up with the challenges imposed by the increasing amount of collected data and the complexity of analysis.
