Higher-level languages proposal
by unknown＠example.com 13 Oct '08

13 Oct '08

Doug Gregor did 98% of the work on this proposal, but it will likely be Torsten or I presenting this proposal next week in Chicago (5-7pm Monday). The short version of the attached text is that we propose the following: - add some extensions to MPI to allow higher-level languages to build their own MPI bindings - if all that works out nicely, deprecate and eventually remove the official MPI C++ bindings Don't let the proposal name fool you -- the features that we're proposing are inspired by letting higher-level language build their own bindings, but some of the issues (e.g., new MPI_BLOB datatype) are fairly wide-reaching. We haven't yet put a "2.2" or "3.0" label on this proposal (which is why I have not entered it in the MPI-2.2 ticket system); I can see valid arguments for both sides. More feedback is required from the Forum first. -- Jeff Squyres Cisco Systems *

Reminder to move items into tickets
by unknown＠example.com 08 Oct '08

08 Oct '08

This is a reminder to move MPI 2.2 items into the ticket system. See https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/mpi22/TicketWorkflow or the mail that Jeff sent on September 8th for more details. Only items that have tickets will be discussed at the next MPI Forum meeting.

Tracking MPI-2.2 progress
by unknown＠example.com 08 Sep '08

08 Sep '08

Note that there are two ways to track what is happening in the MPI-2.2 effort: 1. The Trac we are using has an RSS feed of all activity: https://svn.mpi-forum.org/trac/mpi-forum-web/timeline?ticket=on&milestone=o… (you can tweak that URL a bit if you only want to see specific kinds of events, etc.) 2. You can add your e-mail address to the CC field of any ticket. Whenever changes are made to a ticket, the system will automatically send e-mail to the submitter, owner, and any e-mail address that is explicitly listed in the CC field. -- Jeff Squyres Cisco Systems

Moving proposals to wiki "tickets"
by unknown＠example.com 08 Sep '08

08 Sep '08

Short version: ============== All MPI-2.2 proposal authors are responsible for moving their current wiki proposals to tickets. See this URL for instructions: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/mpi22/TicketWorkflow More details: ============= We have decided to move all the MPI-2.2 proposals to "tickets" (a la a tracking system, rather than continually editable web pages). This will allow us finer-grained searching capabilities, the ability to run reports (e.g., list tickets in a certain status), automatic e-mail updates when tickets are updated, fixed numbering, and so on. I have moved all of my proposals to tickets; the process is pretty straightforward. Most importantly, the wiki markup is exactly the same. Hence, it's mostly a copy-n-paste operation. All proposal authors are responsible for moving their proposals to tickets. Preserve any comments at the bottom of your current proposals as responses on the ticket. See this URL for information on how to create / edit tickets: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/mpi22/TicketWorkflow -- Jeff Squyres Cisco Systems

New proposal: Concurrent MPI_Init() and MPI_Init_thread()
by unknown＠example.com 07 Sep '08

07 Sep '08

Hi all, I've added a new proposal on the 2.2 wiki. Here's the gist of it: The MPI 2.1 standard does not explicitly mention whether it is permitted for one process in an application to initialize with a different thread-level than another. This needs to be clarified. Link to the proposal: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/mpi22/concurrent_init_ini… -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji

MPI 2.2 Summary
by unknown＠example.com 07 Sep '08

07 Sep '08

I'd like to thank everyone for a very productive MPI 2.2 session and especially Jeff Squyres for keeping records and updating the wiki with the results in real time - that was an enormous help. I encourage everyone to read the proposals very carefully and add comments directly to the wiki entries. We need more input from users of MPI as well; please involve any you know in these discussions. Thanks!
