MPI-next
by Schulz, Martin 16 Dec '13

16 Dec '13

Hi all, During the last MPI forum meeting in Chicago we had a discussion on what MPI-next should be and by when we should have it out. We basically looked at five options: - Skip any MPI 3.x and go straight to MPI 4.0 - MPI 3.1 for minor additions and incl. errata, MPI 4.0 for major additions - MPI 3.1 only for errata, MPI 4.0 for anything else - MPI 3.1 for errata, MPI 3.2 for small enhancements, then MPI 4.0 - MPI 3.0.1 for errata, MPI 3.1 for small enhancements, then MPI 4.0 Out of those, the majority favored the second option - create an MPI 3.1 that includes errata and minor additions, followed by an MPI 4.0 later. We left what is minor and what is not out of the discussion for now, though, with the idea to look at the tickets that are ready one by one. Further, a majority favored a rather short timeline for MPI 3.1. In particular, we discussed shooting for making the March meeting the last one during which additions for MPI 3.1 could be read, which would get us to a standard by December. If someone feels this is too short of a timeline and would cause important things for MPI 3.1 to not be included, please speak up and we can continue the discussion over email. Thanks, Martin ________________________________________________________________________ Martin Schulz, schulzm(a)llnl.gov, http://people.llnl.gov/schulzm CASC @ Lawrence Livermore National Laboratory, Livermore, USA

New Logo for MPI
by Schulz, Martin 16 Dec '13

16 Dec '13

Hi all, For those of you who couldn't make it to the the last MPI forum meeting: we had a discussion on which logo should replace our current MPI-2 logo. I'll post the complete slides with all options that we looked at on the MPI forum page, but below are the three favorites after a few straw polls (before minor corrections). We decided to ask the three creators for gray scale and black/white versions and based on these final version have a vote on the new logo in March.

Hi all, I updated the agenda for tomorrow - the main change is the WG time in the morning, which is now for the P2P WG instead of RMA. We still start at 9am.

Re: [Mpi-forum] underground walkways in Chicago
by Jeff Squyres (jsquyres) 10 Dec '13

The Washington stop on the Blue line from ORD is building 14, and the Aon Center where we have the Forum meetings is building 61. Meaning: you can start in ORD, get on the blue line train, get off at Washington, and walk to the Aon Center -- all without going outside.

Re: [Mpi-forum] ABI
by Jeff Hammond 05 Dec '13

05 Dec '13

Todd Gamblin wrote a nice PMPI interposition generator that would partially automate such an implementation once the various object converters were written by people familiar with the various ABIs. I've used it for something related to ABI conversion, albeit much, much simpler, so I'm happy to contribute to this effort, but if and only if Intel resolves the patent issue. If there's another way to do this that doesn't use PMPI, I don't understand enough of how it would work to evaluate if I could contribute. Maybe Squyres can create https://github.com/open-mpi/goldenspike (in reference to http://en.wikipedia.org/wiki/Golden_spike) for people to fork and add the various x2y ABI conversion tools.

relative to discuss@mpich, devel@mpich is the more appropriate place for this. it is not a discussion most users care about. but i fail to see why it is MPICH-specific. even if the goal is not standardization, i think this should remain within the MPI Forum so that there is no appearance of bias w.r.t. which ABI is the best. jeff On Thu, Dec 5, 2013 at 11:42 AM, Jed Brown <jedbrown(a)mcs.anl.gov> wrote: > "Supalov, Alexander" <alexander.supalov(a)intel.com> writes: >> I am afraid I cannot comment on particular snippets of other people's >> email 5-6 year after the events.
