Adds a package for [libSplash](https://github.com/ComputationalRadiationPhysics/libSplash), a high-level library around serial and parallel HDF5 for regular grids and particle data sets. ``` 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 a dependency for [PIConGPU](http://picongpu.hzdr.de), an open-source, many-core, fully-relativistic particle-in-cell code and further software developed at [Helmholz-Zentrum Dresden - Rossendorf](https://www.hzdr.de). libSplash builds in two versions, one without MPI writing domain-decomposed posix-style HDF5 files per process and one (default) with MPI and MPI-I/O ("parallel HDF5") support aggregating into a single file per MPI communicator. libSplash is used in conjunction with [openPMD](http://openPMD.org), see also [github.com/openPMD/](https://github.com/openPMD/). |
