Neither the PlayStation 2 nor 3, however, provided IEEE 754 compliant double precision floating-point arithmetic which was, and is, considered essential for most CERN applications. In 2002, as part of the ongoing search for ever better price-performance ratio computing, as CERN had moved from mainframes to workstations and then PCs, an article on the use of PlayStations suggested the use of even lower cost alternatives. Finally, conclusions are drawn in Section 5. A detailed analysis of the SixTrack case is provided in Section 4, covering the current studies (see Section 4.1) the performance analysis (see Section 4.2) and an outlook on future applications (see Section 4.3). The structure of the paper is the following: in Section 2 an overview of the BOINC project is given, while the detail and specfficities of the various applications running under are given in Section 3, with separate sections, from 3.1 to 3.5, to cover the various applications. Today, active BOINC projects together harness about 7.5 Petaflops of computing power, covering a wide range of physical application, and also particle physics communities can benefit from these resources of donated simulation capacity. The motivation for bringing LHC computing under the Berkeley Open Infrastructure for Network Computing (BOINC) is that available computing resources at CERN and in the HEP community are not sufficient to cover the needs for numerical simulation capacity. This paper addresses the use of volunteer computing at CERN, and its integration with Grid infrastructure and applications in High Energy Physics (HEP). The main results are highlighted in this paper. Thanks to the computing power provided by volunteers joining numerous accelerator beam physics studies have been carried out, yielding an improved understanding of charged particle dynamics in the CERN Large Hadron Collider (LHC) and its future upgrades. ![]() This paper addresses the challenges related to traditional and virtualized applications in the BOINC environment, and how volunteer computing has been integrated into the overall computing strategy of the laboratory through the consolidated service. ![]() 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 BOINC project. The 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.
