[Mpi-forum] Deadline Sep.21 -- Reviews for New Fortran bindings - Formal reading

Hi Rolf,
I found a few things in the collectives chapter:

Why not list sendtype and recvtype on same line?
  MPI_Gather
  MPI_Gatherv
  MPI_Scatter
  MPI_Scatterv
  MPI_Allgather
  MPI_Allgatherv
  MPI_Alltoall
  MPI_Alltoallv
  
At least the count, displacement, and datatype arrays on icollectives need to be marked as ASYNCHRONOUS due to page 202, line 2-5 of mpi-report-F2008-2011-09-08-reviewdoc.pdf

"Once initiated, all associated send buffers and buffers associated with input arguments (such
as arrays of counts, displacements, or datatypes in the vector versions of the collectives)
should not be modifed, and all associated receive buffers should not be accessed, until the
collective operation completes."

MPI_Igatherv
  recvcounts, displs
MPI_Iscatterv
  sendcounts, displs
MPI_Iallgatherv
  recvcounts, displs
MPI_Ialltoallv
  sendcounts, sdispls, recvcounts, rdispls
MPI_Ialltoallw
  sendcounts, sdispls, recvcounts, rdispls, sendtypes, recvtypes
MPI_Ireduce_scatter
  recvcounts

-Adam

Subject: [Mpi-forum] Deadline Sep.21 -- Reviews for New Fortran bindings - Formal reading

Dear all, especially,
dear owners of new MPI-3 tickets, and
dear chapter author,

If a review is missing, we need to execute a line-by-line
formal reading. I expect that nobody want this.

I hope, you all will return your reviews today (Sep. 21)
that I can prepare the ppt with the review-results
for the MPI Forum meeting (Sep. 22).

For most chapters, it is mainly to check the
argument lists of the new bindings.

Responsible:
Special Fortran reviewers:
  "Jeff Squyres" <jsquyres at cisco.com>;
  "Craig E Rasmussen" <rasmussn at lanl.gov>;  (IN SANTORINI)
  "Hubert Ritzdorf" <Hubert.Ritzdorf at EMEA.NEC.COM>;
  "Purushotham Bangalore" <puri at cis.uab.edu>;
  "Bill Gropp" <wgropp at uiuc.edu>;
  "Reinhold Bader" <Reinhold.Bader at lrz.de>

> C) For owners of MPI-3 tickets:
> Please take

> The interfaces are always two:
