Function t8_offset_sendsto

Function Documentation

int t8_offset_sendsto(int proca, int procb, const t8_gloidx_t *t8_offset_from, const t8_gloidx_t *t8_offset_to)

Query whether in a repartitioning setting, a given process sends local trees (and then possibly ghosts) to a given other process.

Parameters:

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

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

  • t8_offset_from – [in] The partition table of the current partition.

  • t8_offset_to – [in] The partition table of the next partition.

Returns:

nonzero if proca does send local trees to procb when we repartition from offset_from to offset_to. 0 else.
