Efficient algorithms for the fast computation of space charge effects caused by charged particles in particle accelerators Zheng, Dawei , 1985- (VerfasserIn) Rienen, Ursula van , 1957- (GutachterIn) Qiang, Ji (GutachterIn) Potts, Daniel , 1969- (GutachterIn) Universität Rostock (Grad verleihende Institution) Universität Rostock Fakultät für Informatik und Elektrotechnik (Grad verleihende Institution) Text theses Text Hochschulschrift 2016 2016 eng electronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource In this dissertation, a Poisson solver is improved with three parts: the efficient integrated Green's function; the discrete cosine transform of the efficient integrated Green's function values; the implicitly zero-padded fast Fourier transform for charge density. In addition, the high performance computing technology is utilized for the further improvement of efficiency, such as: OpenMP API, OpenMP+CUDA, MPI, and MPI+OpenMP parallelizations. The examples and simulation results are matched with the results of the commonly used Poisson solver to demonstrate the accuracy performance.<eng> vorgelegt von Dawei Zheng Dissertation Universität Rostock 2016 Teilchenbeschleuniger Geladenes Teilchen Computersimulation 539.73 539.73 530 UN 6100 ST 340 SK 540 33.56 54.76 31.76 http://rosdok.uni-rostock.de/resolve/urn/urn:nbn:de:gbv:28-diss2018-0013-9 https://doi.org/10.18453/rosdok_id00002019 https://nbn-resolving.org/urn:nbn:de:gbv:28-diss2018-0013-9 https://d-nb.info/1293651419/34 Efficient algorithms for the fast computation of space charge effects caused by charged particles in particle accelerators--(DE-627)875722431 urn:nbn:de:gbv:28-diss2018-0013-9 doi: 10.18453/rosdok_id00002019 oclc: 1029053524 ppn: (DE-627)1016161069
