We discuss the design decisions, design alternatives, and rationale behind the third
generation of Peano, a framework for dynamically adaptive Cartesian meshes derived from …

This contribution describes recent developments and enhancements of the coupling tool
preCICE and the flow solver Peano used for our partitioned simualtions of fluid-structure …

The C++ programming language and its cousins lean towards a memory-inefficient storage
of structs: The compiler inserts helper bits into the struct such that individual attributes align …

The C programming language and its cousins such as C++ stipulate the static storage of
sets of structured data: Developers have to commit to one, invariant data model--typically a …

We present a family of spacetree-based multigrid realizations using the tree's multiscale
nature to derive coarse grids. They align with matrix-free geometric multigrid solvers as they …

Recent advances in supercomputing capabilities pose a multi-faceted data retrieval
challenge to the exploration and visualisation of the obtained results: the bandwidth …

Memory and bandwidth demands challenge developers of particle-based codes that have to
scale on new architectures, as the growth of concurrency outperforms improvements in …

Massively parallel computational uid dynamics codes that have to stream solution data to a
visualisation or postprocessing component in each time step often are IO-bounded. This is …

We propose to integrate the development of component-based simulation codes for
computational sciences and engineering (CSE), the manufacturing of problem solving …

XML and XML Schema are used in the geospatial domain for the definition of standards that
enhance the interoperability between producers and consumers of spatial data. The size …
