• gtreeid – [in] The global tree in which element is in.

• eclass – [in] The element class of the tree.

• rank – [in] An mpi rank.

• element_is_desc – [in] This should be true, if element is its own first_descendant at the maximum level. Must be false otherwise.

Returns:

True if and only if rank is the (first) owner process of element.
