[Mpi3-subsetting] MPI subsetting: charting the way forward atatelecon next week?

[Richard Treumann]

Of course -

An assertion is a statement that the application does not require some MPI
standard feature or semantic guarantee.  It is not a directive to the MPI
implementation. The implementation is free to provide that feature or
guarantee even if the application says it is not needed.

The story is a bit different for a helper library because the library is
logically a more or less opaque part of the application. If the caller of
MPI_INIT_ASSERTED says the application does not require something and then
uses a library that does require that feature or guarantee - the library
must raise an error or adjust its behavior to live within the assertion.
