ArborX::DistributedTree< Kokkos::HostSpace > | distributed_tree |
This class implements a wrapper around ArborX::DistributedTree, the distributed version of ArborX::BVH.
Because ArborX uses Kokkos, Kokkos needs to be initialized and finalized before using this class.

ArborXWrappers::DistributedTree::DistributedTree | ( | const MPI_Comm | comm, |
const std::vector< BoundingBox< dim, Number > > & | bounding_boxes ) |
Constructor. Use a vector of BoundingBox bounding_boxes
as primitives. The BoundingBox objects in bounding_boxes
are local to the MPI process.
Definition at line 83 of file distributed_tree.h.
ArborXWrappers::DistributedTree::DistributedTree | ( | const MPI_Comm | comm, |
const std::vector< Point< dim, Number > > & | points ) |
Constructor. Use a vector of points
as primitives. The Point objects in points
are local to the MPI process.
Definition at line 94 of file distributed_tree.h.
std::pair< std::vector< std::pair< int, int > >, std::vector< int > > ArborXWrappers::DistributedTree::query | ( | const QueryType & | queries | ) |
Return the indices and the MPI ranks of those BoundingBox objects that satisfy the queries
. Because queries
can contain multiple queries, the function returns a pair of indices and ranks and the associated offsets.
Valid QueryType
classes are ArborXWrappers::BoundingBoxIntersectPredicate, ArborXWrappers::BoundingBoxNearestPredicate, ArborXWrappers::PointIntersectPredicate, and ArborXWrappers::PointNearestPredicate,
