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. In addition, based on the measured field errors, beam dynamics simulations have been carried out by taking into consideration different scenarios with and without MBH magnets installed in the accelerator. Experimental data are compared with the magnetic calculations using the CERN field computation program ROXIE and discussed in view of the construction of the final magnets. The geometrical field multipoles, the iron saturation effects, as well as the effects of persistent currents are summarized. In this paper, the measurement results collected so far are presented and discussed. In addition, a double-aperture short model and the first full-length collared-coil assemblies have been produced and measured at ambient temperature. Magnetic measurements have been performed both at ambient and cryogenic temperatures. At present, one double-aperture and five single-aperture short-model magnets have been built and tested.
