Hello Torsten, Jeff and Rich, I'm sorry that I could not attend the discussion at last meeting. Jeff's minutes are not yet available, therefore my opinion may be in contrary to votes at the meeting - then please tell me. My opinion after looking at ticket 254, file chap-coll/coll.tex : I strongly disagree with the current state of the latex source. You reinvented all the old MPI-2.2 markups, i.e., you uncleaned the tex source of exactly one file: coll.tex. All MPI-2.2 markups are removed to allow the usage of Bills macros to mark all new MPI-3.0 changes. I could not find any \MPIupdate{3.0}... or similar markups in your new source. The 73 changes (found be grep'ing "htor") should be done into "current" coll.tex revision 253 and not into a very old revision. There is no chance to do the cleaning again on your current unclean coll.tex revision 254! All these 73 changes should be marked with Bill's macros as ticket {3.0}{109}. If the forum decided to step back to the uncleaned source then it should be done for all sources and not only for coll.tex. Rich and Jeff, I cannot see any comments on ticket #203, nor any review from you. Did you discussed it at the Jan 2010 meeting?

Hello Forum,

I finished my merger of NBC into MPI-3 as we discussed at the last meeting. I did the merge in the following order:

1) I merged all MPI-2.2 changes into NBC rev. 6 (the version that we voted into MPI-3, attached to #109). This was a relatively straightforward manual process.

2) I merged the combined document into the MPI-3 tree. This was much more complex than anticipated because the MPI-3 tree is "cleaned up" (i.e., many change-macros are gone) and after discussion with Jeff, we realized that the script could not be applied to separate chapters. This, I performed a manual cleanup and removed the change macros in this process. This was not as simple as 1) and seems more error-prone.

3) I re-read and compared the colored MPI-2.2 document and the MPI-3 document and committed it as rev. 524.

The ability to highlight the changes between the revisions (particularly the MPI-2.2 changes) were important for the merger. Bill did a great job making those extremely helpful for my review. I would suggest that we use the same or a similar mechanism for MPI-3. Right now, I left all my (b/w) change-macros (\htorchange, defined at the bottom of mpi-macs.tex) in the source so that we can see what changed after MPI-2.2. I would volunteer to transition them to a new mechanism based on whatever we decide.

Please review the document carefully, the changes that I made were not minor and much more intrusive then all MPI-2.2 changes to the collectives chapter. It would be good to have some designated careful reviewers, any volunteers?

I think we strived to have reviews at the March meeting and I was supposed to deliver a draft two weeks in advance. Now we have three weeks left. That is not very long imho, so we might consider to move the review deadline.

Here are some things that I added which we did not explicitly vote on (however, they are minor and straight-forward from our past votes):

1) fixed some typos (missing ")" and removed some spaces where appropriate (see svn diff)

2) added MPI_Reduce_scatter to various lists in the introduction of Chapter 5 (this is a bug in MPI-2.2)

3) added MPI_Ireduce_scatter_block to the listing of nonblocking collectives. Please review the function interface carefully! This was not voted on or reviewed yet.

4) added a \label{} in the p2p Chapter 3 to reference nonblocking progression semantics (they're referenced nowhere else ;-)).

I put two versions of the document online for easier reviewing. Both versions have the MPI-2.2 changes highlighted (purple for removals, red for additions plus the ticket number at the margin) and also the MPI-3 changes (striked out for removals, underlined for additions, limited to Chapter 5).

MPI-2.2: http://www.unixer.de/sec/mpi-2.2.pdf MPI-3.0: http://www.unixer.de/sec/mpi-3.0.pdf

It should be sufficient to review Chapter 5 only. Please let me know if you have any questions or find any problems.

All the Best, Torsten
