Hi,
This echoes in part the current subset proposal (see http://svn.mpi-forum.org/trac/mpi-forum-web/wiki/Subsets).
Best regards.

I have a "pre-proposal" for the Forum, meaning that I have an idea but want to see if others find it valuable before spending the time to turn it into a formal proposal.
The general idea is to create a flexible mechanism to both pass hints from the user application to the MPI implementation and to pass information from the MPI implementation back to the application. Some rough ideas:
- Allow hints to be passed from the app to the implementation on a per- handle basis (e.g., on a specific communicator) - Allow hints to be passed from the app to the implementation for all instances of a handle type (e.g., for all communicators) - Allow hints to be specified before MPI_INIT, or create another variant of MPI_INIT that allows passing hints - Create a mechanism for an MPI implementation to pass arbitrary information back to the user, perhaps in response to an arbitrary query (maybe something along the lines of an MPI_Info in and and MPI_Info out)
Comments?
