[
libSplash aims at developing a HDF5-based I/O library for HPC simulations. It is created as an easy-to-use frontend for the standard HDF5 library with support for MPI processes in a cluster environment. While the standard HDF5 library provides detailed low-level control, libSplash simplifies tasks commonly found in large-scale HPC simulations, such as iter- ative computations and MPI distributed processes.
libSplash is developed and maintained by the Center for Information Services and High Performance Computing (ZIH) of the Technical University Dresden (TUD) in close collaboration with the Junior Group Computational Radiation Physics at the Institute for Radiation Physics at HZDR We are a member of the Dresden CUDA Center of Excellence that cooperates on a broad range of scientific CUDA applications, workshops and teaching efforts. libSplash is actively used in the PIConGPU project for large-scale GPU-based particle-in-cell simulations picongpu.hzdr.de.
libSplash is licensed under the GPLv3+ and LGPLv3+ (it is dual licensed). Licences can be found in GPL or LGPL, respectively.
