In this paper, the accuracy of solving this system by time-serial spectral deferred corrections (SDC) as well as by the time-parallel Parallel Full Approximation Scheme in Space and Time (PFASST) is investigated. PFASST is based on intertwining SDC iterations with differing resolution in a manner similar to the Parareal algorithm and uses a Full Approximation Scheme (FAS) correction to improve the accuracy of coarser SDC iterations. It is demonstrated that SDC and PFASST can generate highly accurate solutions, and the performance in terms of function evaluations required for a certain accuracy is analyzed and compared to a standard Runge–Kutta method.}, month = {Jun}, date = {2012-06-25}, organization = {Domain Decomposition Methods in Science and Engineering XXI, Rennes (France), 25 Jun 2012 - 29 Jun 2012}, cin = {JSC}, cid = {I:(DE-Juel1)JSC-20090406}, pnm = {411 - Computational Science and Mathematical Methods (POF2-411) / DFG project 450829162 - Raum-Zeit-parallele Simulation multimodale Energiesystemen (450829162)}, pid = {G:(DE-HGF)POF2-411 / G:(GEPRIS)450829162}, typ = {PUB:(DE-HGF)8}, UT = {WOS:000347877900061}, doi = {10.1007/978-3-319-05789-7_61}, url = {https://juser.fz-juelich.de/record/171823}, }
