All grown-up; 18 years of LHC@home
/ Cameron, David (Oslo U.) ; Field, Laurence (CERN) ; Van der Veken, Frederik (CERN) ; Høimyr, Nils (CERN) ; Di Croce, Davide (Ecole Polytechnique, Lausanne) ; Gaillard, Melissa (CERN) ; Masullo, Germano (CERN) ; Noble, Cath (CERN) ; Reguero, Ignacio (CERN) ; Reid, Ivan (Brunei U., Darussalam) et al.
LHC@home was launched as a BOINC project in 2004 as an outreach project for CERN’s 50 years anniversary. Initially focused on the accelerator physics simulation code SixTrack, the project was expanded in 2011 to run other physics simulation codes on Linux thanks to virtualisation. [...]

SixTrack V and runtime environment
/ De Maria, R (CERN) ; Andersson, J (CERN) ; Berglyd Olsen, V K (CERN) ; Field, L (CERN) ; Giovannozzi, M (CERN) ; Hermes, P D (CERN) ; Høimyr, N (CERN) ; Kostoglou, S (CERN) ; Iadarola, G (CERN) ; Mcintosh, E (CERN) et al.
SixTrack is a single-particle tracking code for high-energy circular accelerators routinely used at CERN for the Large Hadron Collider (LHC), its luminosity upgrade (HL-LHC), the Future Circular Collider (FCC) and the Super Proton Synchrotron (SPS) simulations. The code is based on a 6D symplectic tracking engine, which is optimized for long-term tracking simulations and delivers fully reproducible results on several platforms. [...]

Extending CERN computing to volunteers - LHC@home consolidation and outlook
/ Cameron, David (Oslo U.) ; Field, Laurence (CERN) ; Giannakis, Nikolas (U. Patras (main)) ; Høimyr, Nils (CERN)
LHC@home has provided computing capacity for simulations under BOINC since 2005. Following the introduction of virtualisation with BOINC to run HEP Linux software in a virtual machine on volunteer desktops, initially started on test BOINC projects, like Test4Theory and ATLAS@home, all CERN applications distributed to volunteers have been consolidated under a single LHC@home BOINC project.

Integrating HPC into an agile and cloud-focused environment at CERN
/ Llopis, Pablo (CERN) ; Lindqvist, Carolina (CERN) ; Høimyr, Nils (CERN) ; van der Ster, Dan (CERN) ; Ganz, Philippe (CERN)
CERN’s batch and grid services are mainly focused on High Throughput computing (HTC) for processing data from the Large Hadron Collider (LHC) and other experiments. However, part of the user community requires High Performance Computing (HPC) for massively parallel applications across many cores on MPI-enabled infrastructure. [...]

LHC@Home: a BOINC-based volunteer computing infrastructure for physics studies at CERN
/ Barranco, Javier (Ecole Polytechnique, Lausanne, LPAP) ; Cai, Yunhai (SLAC) ; Cameron, David (Oslo U.) ; Crouch, Matthew (CERN) ; De Maria, Riccardo (CERN) ; Field, Laurence (CERN) ; Giovannozzi, Massimo (CERN) ; Hermes, Pascal (CERN) ; Høimyr, Nils (CERN) ; Kaltchev, Dobrin (TRIUMF) et al.
The LHC@Home BOINC project has provided computing capacity for numerical simulations to researchers at CERN since 2004, and has since 2011 been expanded with a wider range of applications. The traditional CERN accelerator physics simulation code SixTrack enjoys continuing volunteers support, and thanks to virtualisation a number of applications from the LHC experiment collaborations and particle theory groups have joined the consolidated LHC@Home BOINC project.

TWiki a collaboration tool for the LHC
/ Jones, Peter L (CERN) ; Høimyr, Nils (CERN)
At the European Laboratory for High Energy Physics, CERN[1], the Large Hadron Collider (LHC)[2] accelerator is colliding beams of protons at energies of 3.5 TeV, recreating conditions close to those at the origin of the Universe. The four main LHC experiments, Alice, Atlas, CMS and LHCb are complex detectors with millions of output channels. [...]

Towards a Production Volunteer Computing Infrastructure for HEP
/ Høimyr, N (CERN) ; Marquina, M (CERN) ; Asp, T (CERN) ; Jones, P (CERN) ; Gonzalez, A (CERN) ; Field, L (CERN)
Following the successful inclusion of virtualisation to volunteer computing for theory simulations back in 2011, the use of volunteer computing with BOINC and CernVM has been extended to cover simulations for the LHC experiments ATLAS, CMS and LHCb. This paper describes the status of the BOINC volunteer computing platform at CERN used for LHC@home and how it has been designed to address a heterogeneous environment of different user communities with different computing infrastructure.

Self-service for software development projects and HPC activities
/ Husejko, Michal (CERN) ; Høimyr, N (CERN) ; Gonzalez, A (CERN) ; Koloventzos, G (CERN) ; Asbury, D (CERN) ; Trzcinska, A (CERN) ; Agtzidis, I (CERN) ; Botrel, G (Toulouse III U.) ; Otto, J (Warsaw U.)
This contribution describes how CERN has implemented several essential tools for agile software development processes, ranging from version control (Git) to issue tracking (Jira) and documentation (Wikis). Running such services in a large organisation like CERN requires many administrative actions both by users and service providers, such as creating software projects, managing access rights, users and groups, and performing tool-specific customisation.

Since a couple of years, a team at CERN and partners from the Citizen Cyberscience Centre (CCC) have been working on a project that enables general physics simulation programs to run in a virtual machine on volunteer PCs around the world. The project uses the Berkeley Open Infrastructure for Network Computing (BOINC) framework. [...]
