[mpiwg-abi] meet next week to discuss predefined handle constants

[Koziol, Quincey]

Hui has a good suggestion to the predefined handle issue and he said that he’d post it when it’s ready for review.

I think talking again is a good idea also - I’m free from 9-1pm CT on Monday.

we need to have a meeting to discuss how to implement handles and predefined handle constants e.g. MPI_COMM_WORLD and MPI_INT.  i think we have consensus that we will do e.g. typedef struct MPI_ABI_Datatype * MPI_Datatype;  since that is the only option that provides type-safety.  there is an open question about using integer literal constants (MPICH-style) or addresses (OMPI-style).  there are merits to both.

i want to get consensus so that i can update the ABI proposal one way or the other.https://www.when2meet.com/?18843291-UxaiH is for scheduling.  i will set the meeting time on Monday morning.  i can host Teams or Google Meet.  if you prefer Zoom, you can agree to host it.
