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. [...]

Event generators simulate particle interactions using Monte Carlo techniques, providing the primary connection between experiment and theory in experimental high energy physics. These software packages, which are the first step in the simulation worflow of collider experiments, represent approximately 5 to 20% of the annual WLCG usage for the ATLAS and CMS experiments. [...]

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.

SixTrack project: Status, runtime environment, and new developments

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 optimised for long-term tracking simulations and delivers fully reproducible results on several platforms. [...]

SixTrack Version 5 is a major SixTrack release that introduces new features, with improved integration of the existing ones, and extensive code restructuring. New features include dynamic-memory management, scattering-routine integration, a new initial-condition module, and reviewed post-processing methods. [...]

The Open High Throughput Computing Content Delivery Network
/ Dykstra, Dave (Fermilab) ; Bockelman, Brian (U. Nebraska, Lincoln) ; Blomer, Jakob (CERN) ; Field, Laurence (CERN)
LHC experiments make extensive use of web proxy caches, especially for software distribution via the CernVM File System and for conditions data via the Frontier Distributed Database Caching system. Since many jobs read the same data, cache hit rates are high and hence most of the traffic flows efficiently over Local Area Networks. [...]
