Row/column and global all-to-all.

Communicator selection: Uses row and column communicators for row/column sends. Remaining sends are performed using the global communicator. Point-to-point isend/irecv are used if ptp is set, otherwise a alltoall collective call is issued.

Parameters:

[in]	mp_env	MP Environment
[in]	most_ptp	(optional) Use point-to-point for row/column; default is no
[in]	remainder_ptp	(optional) Use point-to-point for remaining; default is no
[in]	no_hybrid	(optional) Use regular global collective; default is no
