[Mpi3-rma] RMA WG discussion

Hi,

I have a further question to MPI_NO_OP and MPI_{R}Get_accumulate.
I assume that origin_count is not significant for MPI_NO_OP
(such as origin_datatype)
Which count variable defines the number of basic elements to be returned ?

  (result_count, result_type) or (target_count, target_type) ?

Should an error code be returned if the other number is too small ?

Hubert

Subject: [Mpi3-rma] RMA WG discussion

We talked about different items that need to be addressed for (1) MPI-3
Errata (should only be bug fixes, not all small changes), and (2) MPI-3.1.

We still need to discuss the below items in a telecon; this is just a
basic separation we did based on the WG discussion.

MPI-3 Errata
============
1. Ticket #348 -- one of the examples has a bug in it, which should be
fixed.

2. Ticket #350 -- we should state that for MPI_ACCUMULATE with
MPI_NO_OP, the MPI implementation is not allowed to throw an error when
the origin buffer is NULL.

MPI-3.1
=======
1. Ticket #344 -- Shared memory attribute query.

2. Ticket #346 -- Info keys are not consistent across window creation
routines.

3. Ticket #347 -- Info keys are not listed in the appendix.

4. Ticket #349 -- Addition of MPI_Disp_to_aint and MPI_Aint_to_disp.

5. Addition of the MPI_MODE_NOLOAD assertion.  RMA slides have info on this.

6. Info argument addition for req_mem_model.  RMA slides have info on this.
