[Daniel Holmes]

Hi all,

I have created an issue (#34) to correct a bug in example 7.9 and 
created a pull request (#16) for that change.

The issue can be found here:
https://github.com/mpi-forum/mpi-issues/issues/34

The pull request can be found here:
https://github.com/mpi-forum/mpi-standard/pull/16

The diff can be found here:
https://github.com/mpi-forum/mpi-standard/pull/16/files

I will bring this forward for a reading/vote/ticket-0-adjudication at 
the next meeting.

Cheers,
Dan.

> 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.
