LandauKokkosCreateMatMaps

Build the Kokkos device-side P4estVertexMaps used by the DMPLEX Landau collision operator from its host-side reduced quadrature-point map

Synopsis

#include "petscdmplex.h"   
PetscErrorCode LandauKokkosCreateMatMaps(P4estVertexMaps maps[], pointInterpolationP4est (*pointMaps)[LANDAU_MAX_Q_FACE], PetscInt Nf[], PetscInt grid)

Not Collective; No Fortran Support

Input Parameters

• maps - array of vertex-map structs, one per grid, whose device-side representation is to be created

• pointMaps - host-side reduced quadrature-point maps, indexed by element and face quadrature point

• Nf - number of fields (species) per grid

• grid - index of the grid for which to build the device-side map

Note

This is called by DMPlexLandauCreateVelocitySpace() when the Kokkos backend is selected; it is not intended to be called directly by user code.
