The implementation of large-scale finite-element simulations on distributed systemsrequires specific memory management and disk I/O handling. This is due to theimmense spatial and temporal resolutions and the grade of heterogeneous paralleliza-tion, i.e. hybrid MPI/OpenMP. In this thesis, a new approach for storing, visualizingand restoring (referred to as checkpointing) simulation data in the sam(oa)2project ispresented, introducing a parallel storage system based on the HDF5 and XDMF fileformats. The presented implementation measurably reduces disk space usage and filesystem strain, while improving run-time performance compared to previous outputformats.     «
