Re: [Mpi-forum] Feedback needed / Suggested Change to Chapter 8 (related to RMA)

This sounds good to me - deferring the discussion of the semantics to the RMA chapter makes the most sense.

Feedback needed / Suggested Change to Chapter 8 (related to RMA)
by Schulz, Martin 19 Jul '12

19 Jul '12

Hi all, during the final chapter reads, the following issue came up in the section "Memory Allocation" in Chapter 8, MPI Environmental Management. Here is the context > \section{Memory Allocation} > \label{sec:misc-memalloc} > > In some systems, message-passing and remote-memory-access (\RMA/) operations > run faster when accessing specially allocated memory (e.g., memory that is > shared by the other processes in the communicating group on an SMP). \MPI/ > provides a mechanism for allocating and freeing such special memory. The use > of such memory for message-passing or \RMA/ is not mandatory, and this memory > can be used without restrictions as any other dynamically allocated memory. This is followed by the following sentence: > However, implementations may restrict the use of the \mpifunc{MPI\_WIN\_LOCK} > and \mpifunc{MPI\_WIN\_UNLOCK} functions to windows allocated in such memory > (see Section~\ref{sec:1sided-lock}.) This covers the restrictions for 2.2, but not for the new RMA chapter. Therefore, the RMA group (or a subset thereof) suggested to change that sentence to: > However, implementations may restrict the use of some RMA functionality as defined > in Section~\ref{sec:1sided-lock}. and leave the definition of the semantics to the RMA chapter. Please reply to the group if there are any objections or concerns. Thanks, Martin ________________________________________________________________________ Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulzm CASC @ Lawrence Livermore National Laboratory, Livermore, USA

Hi Jeff, Thank you. Do you happen to have the marked-up version as well somewhere? Best regards. Alexander -----Original Message----- From: mpi-forum-bounces(a)lists.mpi-forum.org [mailto:[email protected]] On Behalf Of Jeff Squyres Sent: Thursday, July 19, 2012 2:25 PM To: MPI Forum list Subject: [Mpi-forum] Final document of the night Yesterday at the Forum, we utilized the power of having a few dozen people sitting together in a room and did a LOT of text/ticket/chapter reviews. This resulted in finding a LOT of little issues (and a few big ones). If chapter committee members were in the room, they fixed and committed the text. But for committees that had no representatives in the room, we made the executive decision to make the fixes ourselves, review them, and then commit them. This really helped keep the momentum going, and we made a TREMENDOUS amount of progress yesterday. I apologize if this caused some consternation to chapter authors/committees who were not in the room. ### Please review SVN commit logs and ensure that everything is ok in your chapter. ### Chapter committees *NEED* to do whole-chapter reviews to ensure that everything is a good, consistent state. As Bill mentioned, use the "cleandoc" build. *** To those who were in the room: Thank you thank you thank you for all the reviewing yesterday! I have uploaded a final cleandoc PDF from last night: http://www.open-mpi.org/~jsquyres/unofficial/mpi-report-cleandoc-r1455.pdf Here's the specific items I'm aware of that still need to be done (I'm sure there are other things, too): 1. The names and organizations in the front matter need to be updated (I sent Bill the info yesterday) 2. Change log is still being edited (there's still lots of issues with it; don't bother reviewing it until Rolf has committed a new version) 3. There's 1 last C++ type still showing up in the index; Rolf will fix it 4. Ticket #313 5.

I've updated the credits list - please check. There are a number of problems with the indices. In the example indices, removed functions such as MPI_Type_struct show up. In the MPI Function index, there are names in mixed case; this index is only for the language-independent functions. This usually means the C binding was used where the language-independent (all uppercase) was intended; sometimes it means that the wrong macro was used for a language-specific instance. These need to be corrected. There are still invalid references to C++, especially page 380, line 30. p 790, line 2 "where" should be "were" (in the change log, entry 5) William Gropp Director, Parallel Computing Institute Deputy Director for Research Institute for Advanced Computing Applications and Technologies Paul and Cynthia Saylor Professor of Computer Science University of Illinois Urbana-Champaign On Jul 19, 2012, at 7:24 AM, Jeff Squyres wrote: > Yesterday at the Forum, we utilized the power of having a few dozen people sitting together in a room and did a LOT of text/ticket/chapter reviews.
