[Mpi-forum] MPI_Comm_create_group Meeting

I would like to form a group to review the MPI_Comm_create_group()
proposal (#286) for a formal reading at the next Forum meeting. If you
are interested in joining the discussion, could you please fill in your
availability for a one hour conference call next week:
We have a couple issues to discuss:
1.) The name of the function: MPI_Comm_create_group,
MPI_Group_comm_create, MPI_Comm_create_from_group, ...
2.) The tag argument: Should we use a tag or a "color" to establish a
safe communication conduit on the parent communicator. As discussed at
the Forum, using a tag could conflict with the use of MPI_ANY_TAG on the
parent communicator. A color would avoid this issue, however it could
complicate tag matching.
3.) Changes to the text.
PS- I've attached a copy of the current text with comments from the
formal reading at the last Forum meeting (in Acrobat: Comments ->
Comments View -> Show Comments List for the full list).
