Hi all, Puri asked me to add the following, describing the context and purpose of today’s virtual meeting: There has been some discussion at the last forum meeting about a C11 interface for MPI. This virtual meeting is to get interested parties to see if there is an interest in such new language bindings. Talk to you later today, Martin — Prof. Dr. Martin Schulz, Chair of Computer Architecture and Parallel Systems Department of Informatics, TU-Munich, Boltzmannstraße 3, D-85748 Garching Email: schulzm(a)in.tum.de > On 30.

29 May '18

Hi folks, I just wanted to beg one more time for people to register for the June meeting, particularly if you have any sort of dietary restrictions. I'll be putting in the catering order very soon and I don't want people to be stuck with something they can't eat. Meeting Registration<https://www.eventbrite.com/e/mpi-forum-austin-tickets-45936583558> If you can't register for some reason right now, but you think you will be coming, just shoot me an email with any restrictions you may have and I can take them into account. Thanks, Wesley

Voting reminder/announcement for June 2018 - issue 25
by Skjellum, Anthony 28 May '18

28 May '18

Hi all, On behalf of the Persistence WG, we want to remind everyone of the upcoming vote on Issue #25. We want to give you a chance to refresh your memory on the successful reading we did in Portland, prior to the formal vote planned for Austin that is upcoming. Issue: <https://github.com/mpi-forum/mpi-issues/issues/> <https://github.com/mpi-forum/mpi-issues/issues/> https://github.com/mpi-forum/mpi-issues/issues/25 PR: https://github.com/mpi-forum/mpi-standard/pull/29 PDF: https://github.com/mpi-forum/mpi-standard/files/2044869/mpi32-report-ticket… There are no no no votes of which we are aware with regard to Issue 25. [Try stringing three "no's" together in any other standard other than MPI :-)]. This vote has been 22+ years in the making fyi. The first version of persistent collective operations was proposed in 1995/96 as part of MPI-2. Thank you, Tony Skjellum

Reading announcement for June 2018 - issue 82
by Skjellum, Anthony 28 May '18

28 May '18

Hi all, The Collective WG (with due respect to the RMA WG) would like to read issue 82 (PR 52), Issue: <https://github.com/mpi-forum/mpi-issues/issues/> https://github.com/mpi-forum/mpi-issues/issues/82 PR: https://github.com/mpi-forum/mpi-standard/pull/52 PDF: https://github.com/mpi-forum/mpi-standard/files/2044757/mpi32-report-ticket… There was some discussion on the issue once posted. But, fyi, I am not aware of any objections from the RMA working group folks since this ticket was launched months ago. This functionality is only about nonblocking variants of the constructors and a new destructor, not about communication operations. As with all nonblocking operations, you can't use the output arguments (in this case, windows) till the operation completes; so the implications on communication operations is also clear... none. What may be more "controversial" is an argument of what happens after a nonblocking destructor... so we need to look at both issues 78 and 82 together to get the same sort of semantics with nonblocking destructors in this regard between communicators, files, and windows. I hope this reasoning and approach makes sense to those reviewing. Issue 81 is also related too but focuses on DPM nonblocking constructors/destructor(s). Thank you, Tony Skjellum

Re: [Mpi-forum] Reading announcement for June 2018 - issue 81
by Skjellum, Anthony 28 May '18

28 May '18

Hi all, Sorry, resend! Cut and paste error. Please see this revised announcement. The Collective WG would like to read issue 81 (PR 49), Nonblocking functionality for the "Process Creation and Management" Chapter. Issue:https://github.com/mpi-forum/mpi-issues/issues/81 PR: https://github.com/mpi-forum/mpi-standard/pull/49 PDF: https://github.com/mpi-forum/mpi-standard/files/2044591/mpi32-report-ticket… This is related in concept to Issues #78 and #82. Our goal is orthogonalizing and completing standard with non-blocking operations to allow completely nonblocking MPI-Next programs. Thank you, Tony Skjellum

: Reading announcement for June 2018 - issue 90
by Skjellum, Anthony 27 May '18

27 May '18

Hi all, The Collective and Persistent WGs would like to read issue 90 (PR 51), Front matter material to address the addition of persistent collective communication operations; this impacts the Collective Chapter at present. (No new wording has been added to the Topology chapter or elsewhere in this set of changes as proposed.) Issue: <https://github.com/mpi-forum/mpi-issues/issues/> https://github.com/mpi-forum/mpi-issues/issues/90 PR: https://github.com/mpi-forum/mpi-standard/pull/51 PDF: https://github.com/mpi-forum/mpi-standard/files/2043453/mpi32-report-ticket… This is a consequence of Issue #25 being accepted to the standard. This is not needed if Issue #25 is not voted in successfully. Thank you, Tony Skjellum

Hi all, The Collective WG would like to read issue 78 (PR 48), Non-blocking communicator/file/win constructors/destructors/etc, respectively to "Groups, Contexts, Communicators, Caching," "Topology," and "I/O" chapters. We are pursuing the broadest possible support of completely nonblocking MPI programs and "orthogonalizing the design" of MPI-Next. Issue: <https://github.com/mpi-forum/mpi-issues/issues/> <https://github.com/mpi-forum/mpi-issues/issues/> https://github.com/mpi-forum/mpi-issues/issues/78 PR: <https://github.com/mpi-forum/mpi-standard/pull/> <https://github.com/mpi-forum/mpi-standard/pull/> https://github.com/mpi-forum/mpi-standard/pull/48 PDF: https://github.com/mpi-forum/mpi-standard/files/2043358/mpi32-report-ticket… Correlated tickets will also be read in concert with this ticket (#81, #82). Thank you, Tony Skjellum
