Meetings web site updated
by Jeff Squyres 27 May '10

27 May '10

The logistics page for the June meeting has been updated -- note that we will be in 2 different Cisco buildings this time: http://meetings.mpi-forum.org/Jun_2010_logistics.php I also posted the backlog of slides and attendance lists that I had accumulated. Finally, I re-organized the at-a-glance page to put future meetings at the top and past meetings at the bottom. Please let me know if you find any problems or inaccuracies. -- Jeff Squyres jsquyres(a)cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/

Re: [Mpi-forum] Final version of cleaned up Chapter5 (CollectiveOperations) including NBC
by Graham, Richard L. 27 May '10

This ticket seems to be a small clarification, and I would say it falls within the bounds for very small changes as the chapter is finalized. Also, we all have to vote on this, so I am ok with including this in this round of changes. I know this can be a slippery slope, because small is undefined. rich On 5/27/10 11:37 AM, "Torsten Hoefler" <htor(a)illinois.edu> wrote: On Thu, May 27, 2010 at 09:31:54AM -0500, Rajeev Thakur wrote: > BTW, what is the status of the nonblocking version of > Reduce_scatter_block, which was introduced in 2.2?

This was added as part of the contract to pull all non-controversial things from MPI-2.2 into the NBC chapter. See Section 5.12.9 in the draft document. However, we have one more open thing that is not covered by this contract. This is captured in ticket #223 and I would like to include it in the draft asap, however, the Forum decides how to proceed with it. https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/223 Torsten -- bash$ :(){ :|:&};: --------------------- http://www.unixer.de/ ----- Torsten Hoefler | Research Associate Blue Waters Directorate | University of Illinois 1205 W Clark Street | Urbana, IL, 61801 NCSA Building | +01 (217) 244-7736 _______________________________________________ mpi-forum mailing list mpi-forum(a)lists.mpi-forum.org http://lists.mpi-forum.org/mailman/listinfo.cgi/mpi-forum

BTW, what is the status of the nonblocking version of Reduce_scatter_block, which was introduced in 2.2? It wasn't in the original nonblocking collectives chapter we voted on, but it needs to be added at some point for MPI 3.

This will be the formal reading. Ok, remember that #109 is voted into MPI-3. I was not aware that we also read chapters after we voted in all the parts. So we will then be reading every item twice and will vote on every item four times, correct? We should really have a writeup of those rules and for the directions we chose to go with the draft standards and MPI-3 in general. I am still convinced that we should call the current draft MPI-2.3 and release it. We can read it and vote on it as many times as we want, however, I fear that we have to read/vote chapter 5 again for MPI-3 even though the changes are probably trivial. > >From Rich's May 23rd email: > > "NOTE: We will have the formal reading of the mpi-3 version of the > nonblocking collective operations.

This is a formal reading of the draft Chapter 5 for inclusion in a draft MPI-3 standard.

Voting
by Jeff Squyres 27 May '10

27 May '10

Note that per Rich's May 23rd email, we will have a first formal reading of the non-blocking collectives stuff at the June 2010 meeting. Assuming that all goes well, we will be voting on this chapter in the September and October 2010 meetings. As Rich mentioned, if you want to vote, your organization must physically attend 2 out of the past 3 meetings (including the meeting where the vote is occurring). To be specific, if you want to vote in: * September: your organization must physically attend the September meeting and at least one of the May or June meetings. * October: your organization must physically attend the October meeting at least one of the June or September meetings. -- Jeff Squyres jsquyres(a)cisco.com For corporate legal information go to: http://www.cisco.com/web/about/doing_business/legal/cri/
