The formula in the computation for the number of neighbors in
Conway's Game of Life has an error in it. The second term on the third line
should be u[i-1][j]. That is, the computation is

Section 8.2 (Pages 243ff.)
This is not exactly an errata, but
the section describes several of the
functions for working with MPI_Count, but omits one of the
most important, MPI_Get_elements_x, the
MPI_Count counterpart of MPI_Get_elements.
This routine is described on page 113 in the MPI 3.1 standard.
This is not exactly an errata, but the book was published before
the MPI_T_pvar_get_index and MPI_T_cvar_get_index routines were
officially adopted by the MPI Forum into MPI.
Until those routines become part of MPI, it is necessary to search through all
defined control or performance varibles by index to find the index that
matches a name. Code for that is available on the web site, in the
examples for the chapter ``Support for Performance and Correctness Debugging.''
Figure 10.2, on the right, has MPI_Int where it should have
MPI_Init (MPI_Init_thread would also be correct there).
The figure should be:
