Struct Documentation

struct t8_forest_ghost

This struct stores various information about a forest’s ghost elements and ghost trees.

Public Members

t8_refcount_t rc

The reference counter.

t8_locidx_t num_ghosts_elements

The count of non-local ghost leaf elements

t8_locidx_t num_remote_elements

The count of local leaf elements that are ghost to another process.

t8_ghost_type_t ghost_type

Describes which neighbors are considered ghosts.

sc_array_t *ghost_trees

ghost tree data: global_id. eclass. elements. In linear id order

sc_hash_t *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]

sc_hash_t *process_offsets

Given a process, return the first ghost tree and within it the first element of that process.

sc_hash_array_t *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.

sc_array_t *remote_processes

The ranks of the processes for which local elements are ghost. Array of int’s.

sc_mempool_t *glo_tree_mempool

The global tree memory pool.

sc_mempool_t *proc_offset_mempool

The process offset memory pool.
