int t8_offset_range_send(int start, int end, int mpirank, const t8_gloidx_t *offset_from, const t8_gloidx_t *offset_to)

Count the number of processes in a given range [a,b] that send to a given other process in a repartitioning setting.

Parameters:

• start – [in] The first mpi rank to be considered as sender.

• end – [in] The last mpi rank to be considered as sender.

• mpirank – [in] The mpirank to be considered as receiver.

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

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

Returns:

The number of processes p, such that start <= p <= end and p does send local trees (and possibly ghosts) to mpirank.
