The formulas that generate the information found in Figures 5–9 and 5–10 can
be found in the High Performance Fortran Language Specification.
A visually-oriented technique for reproducing the results of these formulas for
two-dimensional distributions can be found in Section 5.5.6.9.
See Section 5.5.6.1 for a detailed explanation of the format of the figures found
in this chapter.
5.5.6.7 BLOCK, CYCLIC Distribution
BLOCK, CYCLIC distribution is analogous to CYCLIC, BLOCK, with the
opposite orientation. See Figures 5–11 and 5–12.
