It would be interesting to know what the issues with Open MPI are --
hopefully they would be easy to resolve. Since there were two
requests within a week for MPI_SUM/MPI_PROD and MPI_REAL*, I added
support for the functionality in our release branch. It is also
available in the 7.1.3a1 release I posted this afternoon.
