Function Documentation

int t8_offset_sendstree(int proc_send, int proc_to, t8_gloidx_t gtree, const t8_gloidx_t *offset_from, const t8_gloidx_t *offset_to)

Query whether in a repartitioning setting, a given process sends a given tree to a second process.

Parameters:

  • proc_send – [in] Mpi rank of the possible sending process.

  • proc_to – [in] Mpi rank of the possible receiver.

  • gtree – [in] A global tree id.

  • offset_from – [in] The partition table of the current partition.

  • offset_to – [in] The partition table of the next partition.

Returns:

nonzero if proc_send will send the tree gtree to proc_recv. 0 else. When calling, gtree must not be a local tree of proc_send in offset_from. In this case, 0 is always returned.
