A Morton-Type Space-Filling Curve for Pyramid Subdivision and Hybrid Adaptive Mesh Refinement
David Knapp, Johannes Albrecht Holke, Thomas Spenke +2
The forest-of-refinement-trees approach allows for dynamic adaptive mesh refinement (AMR) at negligible cost. While originally developed for quadrilateral and hexahedral elements,…
Alternative quadrant representations with Morton index and AVX2 vectorization for AMR algorithms within the p4est software library
Mikhail Kirilin, Carsten Burstedde
We present a technical enhancement within the p4est software for parallel adaptive mesh refinement. In p4est primitives are stored as octants in three and quadrants in two dimensio…
scda: A Minimal, Serial-Equivalent Format for Parallel I/O
Tim Griesbach, Carsten Burstedde
We specify a file-oriented data format suitable for parallel, partition-independent disk I/O. Here, a partition refers to a disjoint and ordered distribution of the data elements b…
An Optimized, Parallel Computation of the Ghost Layer for Adaptive Hybrid Forest Meshes
Johannes Holke, David Knapp, Carsten Burstedde
We discuss parallel algorithms to gather topological information about off-process mesh neighbor elements. This information is commonly called the ghost layer, whose creation is a…
An AMG saddle point preconditioner with application to mixed Poisson problems on adaptive quad/cube meshes
Carsten Burstedde, Jose A. Fonseca, Bram Metsch
We investigate various block preconditioners for a low-order Raviart-Thomas discretization of the mixed Poisson problem on adaptive quadrilateral meshes. In addition to standard di…
Distributed-Memory Forest-of-Octrees Raycasting
Carsten Burstedde
We present an MPI-parallel algorithm for the in-situ visualization of computational data that is built around a distributed linear forest-of-octrees data structure. Such octrees ar…
