[mpiwg-hybridpm] Hybrid WG telecon reminder: May 5th 11am central

[Jim Dinan]

Expanded agenda:

1. (Jim) Discussion of endpoints query function.  We decided not to pursue
this at this time for two reasons: (1) it's hard to define (is it relative
to another communicator?) and (2) because knowing the number of endpoints
is not helpful, you need the handles and a routine that returns the handles
breaks MPI convention.

2. (Dan) Discussion of communicator comparison routines in the presence of
endpoints.

3. (Pavan) Move toward resolution of MPI_Comm_free.  Currently, the leading
option is to leave MPI_Comm_free as a conventional collective
(MPI_THREAD_MULTIPLE mode is required to free an endpoints communicator).
 We could pursue a lesser-collective MPI_Comm_endpoints_free (i.e. for
lesser threading models) in a future proposal.

 ~Jim.
