Field Documentation

ghost_trees

sc_array_t* t8_forest_ghost::ghost_trees

ghost tree data: global_id.

eclass. elements. In linear id order

global_tree_to_ghost_tree

sc_hash_t* t8_forest_ghost::global_tree_to_ghost_tree

Indexes into ghost_trees.

Given a global tree id I give the index i such that the tree is in ghost_trees[i]

remote_ghosts

sc_hash_array_t* t8_forest_ghost::remote_ghosts

array of local trees that have ghost elements for another process.

for each tree an array of t8_element_t * of the local ghost elements. Also an array of t8_locidx_t of the local indices of these elements within the tree. It is a hash table, hashed with the rank of a remote process. Sorted within each process by linear id.

remote_processes

sc_array_t* t8_forest_ghost::remote_processes

The ranks of the processes for which local elements are ghost.

Array of int's.
