The words describing the tiling for the filetype in figure 10.1 only
mention the need for an MPI_LB to repeat the 1-unit hole at the beginning,
leaving me to wonder about how the 3-unit hole at the end is repeated.
(See page 216, the definition of view, in the May 8 text.)
In the example, with explicit MPI_LB and MPI_UB, I believe the extent of the
filetype is 6 units, and without, the extent is only 2 units. Thus to get
the tiling shown in the figure, I expect an MPI_UB would be needed.
Do others agree with this assessment? If not, can someone explain the
error in my reasoning?
