[1]	15	! Revision 1.2 2004/04/30 13:12:17 raasch
	16	! Switched from mpi_alltoallv to the simpler mpi_alltoall,
	17	! all former transpose-routine files collected in this file, enlarged
	18	! transposition arrays introduced
	19	!
	20	! Revision 1.1 2004/04/30 13:08:16 raasch
	21	! Initial revision (collection of former routines transpose_xy, transpose_xz,
	22	! transpose_yx, transpose_yz, transpose_zx, transpose_zy)

	31	! elements along x reside on the same PE, while after transposition, all
	32	! elements along y reside on the same PE.
