The security model of the ALICE next generation Grid framework / Martinez Pedreira, Miguel (CERN) ; Grigoras, Costin (CERN) ; Yurchenko, Volodymyr (Natl. Acad. of Sci. of Ukraine) ; Melnik Storetvedt, Maksim (HVL, Norway)
JAliEn (Java-AliEn) is the ALICE next generation Grid framework which will be used for the top-level distributed computing resources management during the LHC Run 3 and onward. While preserving an interface familiar to the ALICE users, its performance and scalability are an order of magnitude better than the currently used framework. [...]

Evolution of the ALICE software framework for Run 3 / Eulisse, Giulio (CERN) ; Konopka, Piotr (AGH-UST, Cracow ; CERN) ; Krzewicki, Mikolaj (Frankfurt U., FIAS ; Goethe U., Frankfurt (main)) ; Richter, Matthias (U. Oslo (main)) ; Rohr, David (CERN) ; Wenzel, Sandro (CERN)
ALICE is one of the four major LHC experiments at CERN. When the accelerator enters the Run 3 data-taking period, starting in 2021, ALICE expects almost 100 times more Pb-Pb central collisions than now, resulting in a large increase of data throughput. [...]

The ALICE analysis framework for LHC Run 3 / Berzano, Dario (CERN ; INFN, Italy) ; Deckers, Roel (CERN) ; Grigoras, Costin (CERN) ; Floris, Michele (CERN) ; Hristov, Peter (CERN) ; Krzewicki, Mikolaj (CERN ; Frankfurt U., FIAS ; Goethe U., Frankfurt (main)) ; Zimmermann, Markus (CERN)
The ALICE experiment at the LHC (CERN) is currently developing a new software framework designed for Run 3: detector and software will have to cope with Pb–Pb collision rates 100 times higher than today, leading to the combination of core Online-Offline operations into a single framework called O$^2$. The analysis code is expected to run on a few large Analysis Facilities counting 20k cores and sustainin ga 100 GB/s throughput: this requires a conjoint effort between the definition of the data format, the configuration of the Analysis Facilities and the development of the Analysis Framework.

Software training for the next generation of physicists: joint experience of LHCb and ALICE / Berzano, Dario (CERN ; INFN, Italy) ; Burr, Chris (U. Manchester (main)) ; Beck, Hans (Unlisted, DE) ; Bellée, Violaine (Ecole Polytechnique, Lausanne) ; Bertens, Redmer Alexander (U. Tennessee, Knoxville) ; Puig Navarro, Albert (U. Zurich (main))
The need for good software training is essential in the HEP community. Unfortunately, current training is non-homogeneous and the definition of a common baseline is unclear, making it difficult for newcomers to proficiently join large collaborations such as ALICE or LHCb. [...]

Grid services in a box: container management in ALICE / Storetvedt, Maxim (HVL, Norway) ; Litmaath, Maarten (CERN) ; Betev, Latchezar (CERN) ; Helstrup, Håvard (HVL, Norway) ; Fanebust Hetland, Kristin (HVL, Norway) ; Kileng, Bjarte (HVL, Norway)
Virtualization and containers are established tools for providing simplified deployment, elasticity and workflow isolation. These benefits are especially advantageous in containers, which dispense with the resource overhead associated with virtual machines in cases where virtualization of the full hardware stack is not considered necessary.
