Strong Scaling for Numerical Weather Prediction at Petascale with the Atmospheric Model NUMA
Andreas Müller, Michal A. Kopera, Simone Marras +3
Numerical weather prediction (NWP) has proven to be computationally challenging due to its inherent multiscale nature. Currently, the highest resolution NWP models use a horizontal…
Support for Non-conformal Meshes in PETSc's DMPlex Interface
Tobin Isaac, Matthew G. Knepley
PETSc's DMPlex interface for unstructured meshes has been extended to support non-conformal meshes. The topological construct that DMPlex implements---the CW-complex---is by defini…
Bounds on the number of discontinuities of Morton-type space-filling curves
Carsten Burstedde, Johannes Holke, Tobin Isaac
The Morton- or z-curve is one example for a space filling curve: Given a level of refinement L, it maps the interval [0, 2**dL) one-to-one to a set of d-dimensional cubes of edge l…
