Sharing server nodes for storage and compute Batch on EOS Extra Resources / Schulz, Markus (CERN) ; Jones, Ben (CERN) ; Kiryanov, Andrey (Petersburg Nuclear Physics Institute (RU)) ; Lamanna, Massimo (CERN) ; Mascetti, Luca (CERN) ; McCance, Gavin (CERN) ; Rousseau, Herve (CERN) ; Smith, David (CERN) ; Tollefsen, Havard (Norwegian University of Science and Technology (NTNU) (NO))
Based on the observation of low average CPU utilisation of several hundred disk servers in the EOS storage system at CERN, the Batch on EOS Extra Resources (BEER) project developed an approach to utilise these resources for batch processing. After initial proof of concept tests, showing almost no interference between the batch and storage services, a model for production has been developed and implemented. [...]

When bad archiving results in good art. / Le Meur, Jean-Yves (CERN) ; Volpi, Matteo (University of Melbourne (AU))
A collaboration involving time, nature and slide copies has taken place in the European Organization for particle physics (CERN) between the construction of its Large Electron-Positron Collider in 1985 up to 2017. If CERN is famous for the recent discovery of the Higgs Boson, its quest for the infinity small is also a source of inspiration for many artists - including mold. [...]

Trident: Automated system tool for collecting and analyzing hardware performance counters / Muralidharan, Servesh (CERN) ; Smith, David (CERN)
Trident, a tool to use low level metrics derived from hardware counters to understand Core, Memory and I/O utilisation and bottlenecks. The collection of time series of these low level counters does not induce significant overhead to the execution of the application. [...]

The obsolescence of Information and Information Systems / Le Meur, Jean-Yves (CERN)
In 2016 was started the CERN Digital Memory project with the main goal of preventing loss of historical content produced by the organisation. The first step of the project was targeted to address the risk of deterioration of the most vulnerable materials, mostly the multimedia assets created in analogue formats from 1954 to the late 1990's, like still and moving images kept on magnetic carriers.
