In Figure 7.2 (part of example 7.9, in section 7.6, page 330, line 18),
the call to "MPI_DIMS_CREATE" is erroneous because the first parameter
is given as "comm" rather than "comm_size". To pass "comm_size", the
example would need an extra variable declaration and an extra line of
code (between lines 17 and 18) that calls the "MPI_COMM_SIZE" function.
Cheers,
Dan.
