Daniel Endreß: Generic output for mesh-based supercomputing applications

Various simulations like ExaHype and SeisSol currently use their own implementation of writing the computed data to disk. In order to do so as efficiently as possible all these simulations need to consider several aspects like aligning processes to file system blocks and generating a reasonable structure of output files. Therefore it is useful to have a single implementation that deals with these issues and provides the best writing functionality for such simulations. The challenge here is to find a way to reconcile the differences of mesh-based simulations like dynamic meshes opposed to static meshes or data stored in cells opposed to data stored in vertices. Hence the goal of this master thesis is to create a tool that combines all those varieties of different mesh-based simulations while providing the most efficient way of writing data.
