Comments on Chapter 4 (Collective Communication) of MPI 2.1, draft
2008-02-23:
* This chapter is a merge without change of the original collective comm
chapter in MPI-1 and the chapter on extended collective ops in MPI-2. As a
result, it uses the terms MPI-1, MPI-2, MPI-1.2 all over the place. Are we
still retaining this distinction? If not, the text would need to be edited
carefully to remove those terms. (Not doing it here.)
* The introductory text from the original chapter in MPI-2.0 makes sense
when it is viewed as an extension (add-on) to the chapter in MPI-1. But that
text in its new location in Section 4.3 does not make sense as it is,
because it appears before any of the collective functions have been
introduced. Section 4.3 needs some careful editing to make it fit in its new
position. (Not doing it here.)
* pg 128, ln 5: Say "For intracommunicators, MPI_Barrier blocks the
caller..." and delete the first sentence on ln 7 "For MPI-2, comm may be an
intercomm or intracomm"
* The already officially approved errata, which appear under "MPI 2.0
Errata" at http://www.mpi-forum.org/mpi2_1/index.htm need to be incorporated
in this chapter.
* Chapter 5 on Intercommunication says: "An inter-communicator cannot be
used for collective communication." ln 48, pg 200. That needs to be deleted.

Some comments on chapter 7:
Chapter 7:
Page 247 line 34: MPI_VERSION should be 2
Page 250 lines 1-3: don't need to be red
Page 253 lines 1-2: don't need to be red
Page 253 line 14: Do we want to refer to MPI-2 specifically, or just as
extended error handling ?
Page 262: lines 1-11: Should MPI_ERR_KEYVAL be added to the list on page
261 ?
Page 264: lines 6-16, should this be changed to reflect NULL arguments to
MPI_Init() w/o backward reference to MPI 1.1 ?

Here is a first cut at comments on chapter 3. It looks good overall. Some
of these comments, I am sure, are relevant once the automated part is done,
as it involves text changes referring to the new document.
Rich
Chapter 3:
**********
What about signed char - it should also be in the basic data section. In
addition, this and wide char and unsigned long long should go into the data
type table.
Pate 34, line 1-6 - ok, but marked in red. They are from the original 1.1
document.
Page 39 is incorrect. Lines 36-38. there is a standard definition in
Fortran 2003 for fortran/C interoperability.
Page 53: lines 30-34, need to get the correct reference based on the new
document. (also, unmarked as moved text)
What happened to section 4.5/4.5.1 from the MPI 2.0 standard. 4.5.2 made it
over.
Page 69 line 7 incorrectly states that there are four ways to create
persistent communication request. The correct number is 5 - 4 send, 1
receive.
Page 72, lines 34-38 need to reference the correct pages in the combined 2.1
document.
Page 76 lines 1-4 should not be colored. They are from the 1.1 doc.
Page 76 line 39: Do we still want to keep the name New in the title ? This
also seems out of place.
Page 77 lines 1-12 should be merged with the text, with the MPI 1.1 versions
explicitly marked as deprecated.
Page 94: lines 42-46, reference the correct pages in the new combined
document.
Page 95: lines 2-4, do we need this explanation ?
Page 95: line 21-22, change to page reference in the new document.

Please can you print the MPI-2.1 Ballot 3 and 4 pdf-files for the March
meeting. This may help that you can check open questions during the
meeting together with your MPI 1.1 and MPI 2.0 standard (e.g. on your Laptop).
Ballot 4 slides can be found here: (slides)
http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/mpi_21…
Ballot 3: (latex based document)
http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/ballot…
This files are also linked at
http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/
At the March meeting, MPI-2.1 has 4 different topics:
- Ballot 3 (clarifications to MPI 1 and 2) first official vote
- Ballot 4 (clarifications to MPI 1 and 2) first official reading
- MPI-1.3 (combinded document: MPI-1.1 + 1.2) review
- MPI-2.1 (combinded document: MPI-1.3 + 2.0) review
Best regards

Rolf & others,
I have completed my review of Chapter 1 of the MPI 1 + 2 merging
document.
It looks pretty good.
I did notice two sentences on page 4, section 1.4, lines 13 and 14
that apply to MPT 1.2 but not to MPI 2. This seems wrong in an MPI 2.1
standard document. Can we delete the following two sentences from the
merged document?
"Although no explicit support for threads is provided, the
interface has been designed so as not to prejudice their use. With
this version of MPI no support is provided for dynamic spawning
of tasks."
If we do that, we could combine the sentence at line 11 about MIMD and
SPMD with the next paragraph that starts at line 15. This is the sentence
I'm referring to:
"The interface is suitable for use by fully general MIMD
programs, as well as those written in the more restricted style
of SPMD."
