Thanks for the suggestion. I have now replaced the previous message with your
suggested one.

The primary reason is because Fortran 2015 has features that support the
writing
of fault-tolerant parallel algorithms. GCC 7 supports these features using
OpenCoarrays,
which in turn uses features that are in MPICH 3.2. I don’t think there is
anything
comparable in an OpenMPI release yet, although I’m aware that OpenMPI
developers are
working on it.
Nonetheless, I would be glad to add a “—-with-mpi” flag that would enable users
to specify
the MPI of their choice. We could also allow for non-MPI options. For example,
OpenSHEM
has been tested as an alternative recently. Either way, I’m thinking I’ll hold
off on
investing any more time in this patch for now. It seems unlikely to be
approved for the
trunk until other work completes and it’s uncertain when the other work will
complete.
