ExaHyPE goes HDF5

Tobias Weinzierl, Durham University, UK, Sven Köppel, FIAS, Germany, Michael Bader, TUM, Germany, HDF Guest Bloggers ExaHyPE develops a solver engine for hyperbolic differential equations solved on adaptive Cartesian meshes. It supports various HDF5 output formats. Exascale computing is expected to allow scientists and engineers to simulate, and ultimately understand, wave phenomena with unprecedented accuracy […]

Parallel and Large-scale Simulation Enhancements to CGNS

The current improvement of using collective I/O to reduce the number of independent processes accessing the file system helped to improve the metadata reads for cgp_open substantially, yielding 100-1000 times faster execution times over the previous implementation.
